How to turn the PCs you have
Simple. Just plug in the CXI 3270 PC connection. It's an add-in board with software. And it can turn your IBM®PC, XT, AT or compatible into a fullfledged coaxial- or modem-attached 3270 PC. Just like that. So you can access and "window" up to five host applications at the same time. On the same screen. There's also
a window for running a PC DOS application. Which can be programmed to talk with any host session-or all five at once. Not to mention two electronic notepads.
The coaxial connection attaches to a 3274 cluster controller. While the modem connection lets you work remotely without the need for a controller.
It gets better. Our 3270 PC connection lets you use
into the 3270 PCs you need.
inexpensive PC-attached printers in place of host-addressable IBM 3287s. And it can run all the software already written for the IBM PC. What's more, international keyboard mapping and file transfer come standard. For those who don't require full 3270 PC capability, we also offer the CXI 3278/79 PLUS PC connection. It lets you work with one host session,
one PC program and two notepads-concurrently.

EDITORIAL
DIGESIS EXPAND TO DATA COMMUNICATIONS
This , our first Communications Digest, is one of four special Mini-Micro Systems issues to be published this year. Like our Computer Digest, issued each June, the Communications Digest will be published annually in February. These two, along with our Peripherals Digests, published in April and November , make up our 1985 digest schedule.
We have chosen 1985 to introduce our first Communications Digest because it's a year in which most system integrators are expected to incorporate data communications features into their value-added products. Interconnectability · of computer systems has clearly risen from a desirable feature to a necessity. As we approach the 1990s, interconnectability will increasingly reshape the architectures of almost all computer systems. No longer can system integrators view their products as only standalone solutions.
This year , all computer system designers will have to be aware of the data communications standards now in place and the many that have yet to be specified . To learn about the standards, or lack of standards, in each of five product categories , turn to the staff-written articles that begin each Digest section. Then, to see which products are already on the market, turn to the product guide following each article .
Since the new Communications Digest is published in February, Mini-Micro Systems' regular data communications issue (traditionally scheduled for March) now moves to September. Continuing unchanged in our 1985 editorial calendar are two other special-emphasis issues-June's State of the Market Report and December's State of the Technology Report.
As noted in 1984's Fall Peripherals Digest, we have modified the product categories in our peripherals digests so that each category is covered once a year. The Spring Peripherals Digest will cover flexible , optical and rigid disk drives and subsystems with platter sizes of 8 to 14 inches; line printers and page printers ; 1/2-inch cartridge tape drives ; monitors; and graphics terminals. The Fall Peripherals Digest coverage will include flexible and rigid disk drives and subsystems with platter sizes up to 51/4 inches; matrix and solid-font character printers; 1/4-inch and smaller cassette/cartridge tape drives; and alphanumeric display terminals.
Our job is to provide timely and complete coverage of product developments in the value-added market. If you have suggestions for improving our product coverage , please send them to the Editor-in-Chief, Mini-Micro Systems, 221 Columbus Ave. , Boston , Mass. 02116.

THE NIU-180 LOWERS COST-PER-CONNECTION.
Announcing the NIU-180: the first of an extraordinary new family of Network Interface Units that represents a direction everyone's been waiting for in local area networking. Much higher performance. Much lower cost.
In terms of cost-per-connection, the eight-port NIU-180 is the lowest ever.
In areas where equipment is concentrated, the NIU-180's eight RS-232 ports bring per-connection local area network costs to anew low.
With 16-bit architecture and advanced VLSI, we've packed more memory, more functionality, and more flexibility than ever before into a single unit. At substantially reduced costs.
Because these are Net/One®NIUs, the connections can be with the medium of your choice. Broadband, baseband, optical fiber.
And because these NIUs®are Net/One products, they are a compatible extension of Net/One. The only difference is even higher performance than you've come to expect from what was already the high performance standard. More speed. More power. Less money.

THE NIU-130 LOWERS COST-PER-LOCATION.
Announcing the NIU-130: a two-port NIU that can follow you anywhere at a cost-perlocation so reasonable that network connection is feasible where it hasn't been beforeparticularly in broadband applications. A one-person station on the production floor. An isolated office. A surveillance site.
The NIU-130 unplugs and moves with you easily, and is, like all Net/One products, media-independent.
It takes full advantage of VLSI as well as 16-bit architecture to do more than a single NIU has ever been able to do before. More features. Higher performance. At a cost that keeps the total system cost way down, even when you have to make connections way out.

Lstalling a worldwide 2400bps dial line data network can save you thousands of dollars in international data communications costs. But before you put your John Hancock on a purchase order, check the facts. To be legally used in most foreign countries, today's 2400bps modems must not only comply with the V.22bis Recommendation, but must also meet dozens of additional design and performance requirements as outlined by each country. And the truth is, most don't. In fact, there is only one company whose family of V. 22bis modems has been approved and accepted by over thirty-five foreign nationsConcord Data Systems. Concord was the first company to install a V.22bis-compliant 2400bps modem . And, with over 20,000 units in place today, Concord Data is not only the most popular name in 2400bps modems, but is the benchmark for 2400bps modem performance.

BELL SYSTEM BREAKUP REDIRECTS MODEM MARKET
Dedicated phone line price increases, coupled with decreasing prices for dial-up service,
spurs use of higher speed DOD modems
Stephen J. Shaw, Washington Editor
One event has profoundly affected the modem market. The breakup of the Bell System has resulted in sharp price increases for dedicated phone lines and vigorous competition for dial-up service. This has created a market opportunity for the manufacturers of higher speed Direct Distance Dial (DDD) modems, especially those operating at 2,400 bits per second (bps).
The Bell breakup has also created a dearth of technical transmission standards for modems operating at 2,400 bps and higher. The venerable Bell standard specifications for 300- and 1,200bps, half- and full-duplex modems-103 , 113, 212 and 212A-still retain their hold within the U.S. modem market. However, AT&T Information Systems (ATTIS) has not moved to develop , or impose , standards for higher speed equipment.
Filling this void have been specifications formulated by the Comites' Consultatif Internationale Telephone et Telegraphique (CCITT) , the standards arm of the International Telecommunications Union. U .S. manufacturers are increasingly designing their equipment according to the CCITT specifications for both domestic and international applications.
"There's been a drift away from Bell standards with the breakup," explains Stephen Durham , vice president of product planning and applications for Cermetek Microelectronics Inc., Sunnyvale, Calif. "Even AT&T Information Systems is talking about CCITT-compatible products . "

Despite decreasing per-unit prices, rising demand for 1,200-bps, full-duplex modems are expected to push the dollar value of units shipped to $334 million in 1988.
The net result is to allow'. manufacturers to .cease what Durham characterizes as the "the insanity" of developing two separate productsone under a Bell standard and the other CCITTcompatible-for identical domestic and international applications.
Freed from having to develop U .S.-only versions, manufacturers can devote more resources to designing and marketing products for European , Asian and other countries that adhere to CCITT standards for domestic communications.
U.S. modems resemble foreign counterpart
At the same time as U.S.-made modems more closely resemble their non-U.S. counterparts, many foreign governments have begun to liberalize the procurement of modems and other telecommunications equipment that interconnect with state-owned telephone networks. And the telecommunications agencies of many countries have opened their network-interconnect markets to foreign equipment suppliers. This is partly in response to the AT&T breakup, but also to threats of tariff legislation from Capitol Hill and some diplomatic arm-twisting from the U.S. State Department and the U.S. Trade Representative's office of the Commerce Department. In addition, several countries, most recently Japan, have liberalized their policies toward the provision of value-added information networks, which is likely to spur modem demand in those countries as subscribers increase.
The Bell divestiture has also unleashed a host of potential new customers for modem manufacturers. No longer a captive market for Western Electric equipment, the former Bell operating companies are free to shop around. The inde-

pendent Bell companies, their subsidiaries, and other OEM customers represent an increasingly significant market, according to Kim Myhre , communications industry analyst at International Data Corp . (IDC) , Framingham, Mass.
Market shift spawns products at 2,400 bps
With private or dedicated line price increases , the 2,400-bps DOD modem has become very attractive. Modems operating at 2,400-bps have been used generally for business applications to carry data to and from "dumb" or low-speed , remote, batch terminals. The market has been dominated almost exclusively by modems requiring the four-wire connections used for privateline service almost exclusively, according to John Krayeski , ATTIS manager for modem products. However, numerous full-duplex modems have recently been announced that achieve the same 2,400 bps throughput over the two-wire channels used in the public dial-up telephone network.
The market for 2,400-bps, full-duplex modems had once been the exclusive domain of Concord Data Systems Inc., a small, Waltham, Mass., manufacturer . Earning $1 .5 million in revenues during 1982, Concord Data's first year in operation, the company recorded $14.9 million in revenues last year from its CDS 224 line of 2,400-bps full-duplex modems. " We had the
market to ourselves for almost two years," says C. Kenneth Miller, Concord Data's president , "but there's a lot of people coming into .the market now."
By late last year, only two other manufacturers, Codex C9rp., Mansfield, Mass., and Micom Systems Inc. , Chatsworth , Calif., were shipping 2,400-bps, full-duplex modems for dial-up applications. But that situation is about to change dramatically. Other vendors who have either announced similar modems recently , or are rumored to have a 2,400-bps full-duplex modem under development, include: ATTIS, Case/ Rixon Communications Inc. , Cermetek Microelectronics Inc., Gandalf Data Inc. , General Datacomm Industries Inc., Hayes Microcomputer Products Inc., Multi-Tech Systems Inc., Novation Inc., Penril/Datacomm Inc., Racal-Vadic Inc. and U.S. Robotics Inc.
The sudden appearance of so many vendors in what was once considered a specialized market niche can be explained by the convergence of three distinct industry trends, explains IDC's Myhre. First , users are nervous about privateline rate increases and are looking for dial-up alternatives that can satisfy their medium-speed , data communications requirements. Secondly, the growing use of personal computers in business is pushing users to demand more speed and

data throughput from dial-up modems. Finally, VLSI technology is allowing manufacturers to introduce 2,400-bps modems that are only roughly 50 percent more expensive than 1,200bps units, but deliver twice as much information in the same amount of time.
Prices, delays deter customers
"Private~line costs are going up while longdistance (dial-up) rates are dropping, " says Myhre. As a result , more businesses are looking at dial-up switched service as a cost-effective solution for their data communications needs. Full-duplex , dial-up modems are also finding applications as an interim measure for customers waiting to receive private-line service from AT&T. That has taken up to 160 days .
Manufacturers concur that development of these new modems for business applications has been driven by user demands for increased datatransfer rates. " We're reacting to user need, and users have been crying for more speed over the past year," comments Gary Betty, marketing and sales director for Hayes Microcomputer Products, Norcross, Ga. "Everybody else in the industry has seen the same trends and performed the same market analysis that we have."
It may not be too long before 2,400-bps, full-duplex modems show up in the home, predicts John Borden, a home computer analyst with The Yankee Group, Boston . He says that acceptance of the medium-speed modems for home-computer applications depends on two factors: reducing retail prices to below $700, the approximate level at which 300 to 1,200 bps began to attract home consumers two years ago , and increasing use of home information subscription services and communications software packages that offer graphics capabilities.
At 1,200 bps, Borden continues , a single frame of videotex takes 20 seconds to create. A 2,400-bps modem would, obviously , cut that time in half and could make graphic-based information services more attractive to home users . "I anticipate that by late 1985 we may see some 2,400-bps modems begin to be available in the home," Borden suggests. "But a lot depends on how well home information services are received. "
2,400-bps modems sold to Tymnet
Support of 2,400-bps, full-duplex data transmission by commercial information and network services is also deemed critical if the spate of new modems for dial-up applications is to become widely accepted . Concord Data Systems has already attracted Tymnet Inc., a value-added data network vendor, as a customer. Tymnet has

incorporated Concord's modems by selling them to network subscribers under the TymNet label, says Steve Puchkoff, Concord's vice president of sales.
However, only one other commercial information service, NewsNet, currently supports 2,400bps transmission speeds . Others, including Dialog , Lexis, Telenet, The Source and Uninet are reportedly looking at whether to support 2,400bps transmission rates in addition to existing 300and 1,200-bps connections.
Single-unit prices for the new modems range between $800 and $1,500, depending on additional, value-added features. Prices should remain relatively stable through 1985, says Cermetek 's Durham, but will drop during the following year by an estimated 10 percent to 15 percent. In ·the meantime , manufacturers are expected to compete on the basis of capabilities added to differentiate their products in the market. Such features as auto-dial , auto-answer and self-diagnostics are now considered almost mandatory with the new modems . But manufacturers are already starting to incorporate even more

advanced value-added ·features, including network diagnostics to pinpoint transmission problems along the telephone circuit, error detection and correction, and adaptive line equalization.
Growing sophistication
Two-wire dial-up options are available at 4,800 bps , but the price is relatively steep due to the increased capabilities needed in the modem. Running data through the switched telephone network, says Gunnar Thordarson, data communications product manager for Anderson Jacobson Inc., San Jose, Calif., mandates echo-cancelling techniques to reduce long-distance line noise, and makes error detection and correction capability advisable. Thordarson says Anderson Jacobson is the only manufacturer offering both features in its AJ 4048, full-duplex, 4,800-bps modem. The single-unit, list price of the 4048, $2,595, reflects the significant cost of adding those capabilities, especially when compared with the new 2,400-bps modems that can be purchased for almost one-third the price .
Other manufacturers question whether that
added development cost would be better spent on products operating at 9,600 bps. Lee Schank , president of Case/Rixon in Silver Spring, Md ., asserts "4,800 is an unnecessary stopping point ." Dial-up modems operating at 9,600 bps require both echo-cancelling techniques and equipment that is expensive to develop and manufacture . " The cost differential between 4,800 and 9,600 modems is insignificant. (That is,] if you're going to invest in the VLSI technology and software programs that automatically adjust the modem's data output according to the changing line conditions. "
Full-duplex modems operating at 9,600 bps for dial-up applications will make their first appearance by the end of the year, says Hank Morgan , product line manager at Gandalf, in Wheeling , Ill. He adds that international standards for 9,600-bps, full-duplex modems were adopted by the CCITT only in April 1984. " By the end of "85, somebody will be delivering 9,600 , fullduplex equipment."

was unfettered in 1982 to supply telecommunications hardware and computer equipment. According to the most recent IDC estimates, ATTIS captured, by the end of 1983, 16 percent of the market for modems operating at 0 to 600 bps. In this low-speed market, ATTIS ranked just 0.7 percent behind leader Hayes Microcomputer Products. ATTIS is the leader in the 1,200-bps, half-duplex segment, with 22.2 percent of the market. At 1,200 bps, full-duplex , ATTIS has an 11.7-percent market share , lagging behind Racal-Vadic, Sunnyvale , Calif , (31 percent) and Case/Rixon (22.3 percent).
Half-duplex, 1,200-bps market mature
The market for 1,200-bps, half-duplex mo-
dems has matured, with vendors scrambling to
remain price-competitive, according to Case/
Rixon's Schank. Increased use of very large-
scale integration (VLSI) manufacturing tech-
niques are expected to help reduce "plain
vanilla" 1,200-bps, half-duplex modems to prices
under $200 by the end of 1985, according to The
Yankee Group's estimates. Due to a sluggish 7.2-
percent predicted annual increase in demand,
combined with falling prices , the value of
modem shipments is expected to rise from $40.9
million in 1983 to $42.8 million in 1988, a paltry
$1. 9 million increase over five years.
The slack, in the half-duplex market segment ,
however , will be taken up by the 1,200-bps ,
full-duplex equipment. The full-duplex version
allows data to be simultaneously transmitted in
both directions on two- rather than four-wire
telephone circuits. With dial-up business tele-
phone and private-line charges going up, and
technological developments such as VLSI tech-
niques bringing costs down, full-duplex , 1,200-
bps modems are receiving an enthusiastic recep-
tion from users. IDC estimates that this segment
will grow at an annual rate of 25 .7 percent
through 1988. From 268,600 units shipped in
1983, 1200-bps, full-duplex modems are pro-
jected to jump to 845,000 units shipped in 1988.
Overall, industry analysts continue to see
healthy growth in most sectors of the modem
market during the next four years, in spite of the
increasing availability of digital-transmission
lines in local and wide-area data networks. Ac-
cording to IDC's market projections, growth in
unit shipments is expected to average 18.7 per-
cent annually through 1988.

What do you get when you cross 1200 baud, free on-line time, and extra features at a price Hayes can't match?
Shopping for a modem doesn't have to be a riddle . A tedious sifting through claims and counterclaims. A quest for the best that raises more questions than it answers.
The new MultiModem, from Multi-Tech Systems, gives you the right answers from the start. The answers to all your questions about what a first-rate intelligent modem should do for you.
MultiModem.
Data Transmission
Speed?
The MultiModem gives you a choice-either 1200 or
300 bits per second. 1200 for fast, efficient communications and lower long-distance
charges. Like when you 're downloading data from the corporate computer, or swapping files with a friend across the country. 300 bps for your less demanding applications, like checking out bulletin boards, playing games, or having on-line keyboard conversations .
Free On-Line Time?
With the MultiModem you get CompuServe's DemoPak -a free two-hour demonstration of their service, and up to seven more free hours of online time if you subscribe. You also get a $50 usage credit from NewsNet, a service which lets you tap into 150 different specialized business
Hayes-compatibility?
Yes, the MultiModem is Hayes-compatible. (Most software requires modems that are.) That means the MultiModem will run with popular communications programs like Crosstalk XVI , Data Capture, PC-Talk Ill , our own MultiCom PC , and dozens of others.
What About Price?
At $549, the MultiModem retails for $150 less than the Smartmodem ' ". You get Hayes-compatibility and so much more-for so much less.
newsletters.
Intelligence? Extra Features?
Of course, the MultiModem automatically dials, answers, and disconnects. But it does a few extra things too, things the Hayes Smartmodem 1200TMdoesn't. Like recognize dial tones and busy signals, so the MultiModem will automatically redial , or automatically try a different number. And it remembers phone numbers too, up to six of them , in its battery-backed memory.

MULTIPLEXERS
MULTIPLEXERS KEEP PACE WITH DATACOMM NEEDS
As communications networks increase in size and complexity, multiplexers are meeting the challenges
of proliferating terminals, rising datacomm costs arid T1 , X.25 and satellite links
Jesse Victor, Associate Editor
As the proverbial terminal begins to appear on every proverbial desktop , spiraling data-transmission costs threaten the proverbial bottom line of every company, laboratory , factory or university faced with growing communications needs. Terminals and PCs have to be connected to host computers in the next building, another city or on another coast. Installing cabling for each device or leasing multiple dedicated telephone lines can be expensive for five terminals and prohibitive for 500.
Multiplexers' key role in reducing datacomrn line costs has thus assumed added importance in today's complex communications networks. Technologically , too , they have kept pace with users' needs by adding functionality- integrating functions previously performed by other types of datacomm equipment. Low-end and mid-range units are providing data-switching and control capabilities, diagnostics, integrated modems and are performing rudimentary network managment. High-end devices are beginning to take over some of the functions of communications processors and meeting the demands for greater bandwidth and higher transmission speeds by furnishing packet assembly/disassembly (PAD) for X.25 packet-switching systems and by interfacing with satellite links.
Communications planners and system integrators are increasingly turning to multiplexers capable of interfacing with AT&T Communications' Tl digital lines as a cost-effective means of integrating large numbers of remote terminals

Multiplexers adding capabllitles
"Multiplexers and modems are starting to be commodity products ," asserts ,Richard Amster, director of data communications research at The Yankee Group, Boston. " Vendors are trying to

"The normal interval we quote customers is a nine-to12-month delay for installing a T1 line'
differentiate their products by integrating functions, increasing capabilities and putting in some network-management features."
"Smaller vendors, particularly, are adding more features at the same product price," adds Laura Schlafly, product line manager for multiplexers at Racal-Milgo, Fort Lauderdale, Fla. . " Data-communications functions are merging," agrees Pat Jordan, senior consultant at Datapro Research Corp., Delran, N.J. "They all now have their niche but are starting to overlap. High-end multiplexers, for example, are merging into front-end processors."
The greater capabilities of today's multiplexers and upward integration of functions is good news for end users and system integrators who need datacomm systems that perform a greater variety of services at lower cost. "The (multiplexer] buyer has a much greater variety of very sophisticated equipment at reasonable prices than ever before," emphasizes Ken Bosomworth, president of market research firm International Resource Development (IRD), Norwalk, Conn.
Typical of the greater functionality of low-end and mid-range units is the data-switching ability of multiplexers from Comdesign Inc., Gandalf Data Inc., Teltone Corp. and other manufacturers. Combining the functions of a port-contention unit and a digital matrix switch, they allow selection of ports under program control and on a demand basis, and provide limited network management.
Gandalfs .Switchmux statistical time-division multiplexer (STDM), for example, concentrates synchronous data transmitted at rates to 4,800 bits per second (bps) from as many as four users, and asynchronous data to 19.2K bps from as many as 16 users. All this data is concentrated into one or two 64K-bps synchronous composite links. Dynamic contention switches local and remote users , selectable by service name, among free ports. The dual links permit loadsharing and automatic switchover in the event of failure, and data integrity is ensured by 16-bit cyclic redundancy check (CRC) error detection with automatic request for repeat (ARQ) of transmitted data. Passwords protect access to the system console and user ports. System-management functions include usage and error statistics and diagnostics.
Offering even higher capacity, Teltone's M-861 handles as many as 32 full-duplex, 9,600bps asynchronous channels or eight 9,600-bps synchronous data streams at composite-link speeds to 76.8K bps. Two to 18 composite links can be supported.
SIX MANUFACTmERS CONTROL NEARLY HALF OF THE

For widely dispersed terminals, multidrop STDMs, such as the 670 Series from Codex Corp., permit dumb asynchronous terminals to share one four-wire, 4,800-bps leased line to the host-computer site. With the master unit at the host computer and slave units in as many as eight remote sites, the master polls the slaves for activity, allowing as many 16 terminals to operate as if each had a dedicated line to the host. STDMs take over
Indeed, most analysts see intelligent statistical multiplexers, such as the Codex, Gandalf or Teltone units as supplanting time-division multiplexers (TDMs), and particularly data concentrators, in most datacomm applications. STDMs constitute one of the fastest growing areas of the multiplexer market, asserts Bosomworth: "STDMs are taking over. Stat muxes are going way beyond statistical techniques. They are using other techniques such as data compression to get more effective utilization of the data line. TDMs are a fading market." Another market researcher, Frost & Sullivan Inc., New York, forecasts a " dramatic switch" by users from the older timedivision .multiplexers to "more advanced" statistical multiplexers.
Other analysts, however, don't see such a quick demise for TDMs. These units sequentially gather data from connected terminals, assign each a fixed number of time slots, then transmit the data sequentially in blocks over the highspeed line for separation by the receiving multiplexer. TDMs are generally most efficient when
40
MINI-MICRO SYSTEMS/February 15, 1985
MULTIPLEXERS
all terminals transmit at or ne'ar their maximum rate ; bandwidth is wasted when fill bits are transmitted in place of data. The generally more expensive STDMs , in contrast , assign bandwidth (and time slots) dynamically according to the amount of terminal activity, not according to a fixed pattern , thus maximizing bandwidth utilization .
" STDMs generally offer more effective utilization of the line ," explains Datapro's Jordan, " but there are applications where the TDM is still most effective. In an IBM Corp. 3270 SNA environment, for example , you are better off with a TDM because SNA does what a stat mux does and fills the line. It's not cost-effective to use a stat mux in this environment." System integrators and end users should select the most cost effective , not necessarily the most technologically advanced , device for their application, Jordan emphasizes. " Saving money is the bottom line in the multiplexer market."
"STDMs do not work very well at high speeds," says Kevin O'Connor, account manager for multiplexers at Timplex Inc. , Woodcliff Lake , N.J. "There is no delay with TDMs on a wideband pipe. " O'Connor is skeptical of exaggerated claims for STDMs , which he says are sometimes propagated by multiplexer vendors who don't offer a broad line of devices. "The TDM market is still very strong," he claims, "and it's going to increase , [even] if not to the level to which the STDM market is going to grow . "
Predicting strong market growth
Despite disagreement on technology , most analysts concur that the overall multiplexer market will enjoy solid growth. Bosomworth predicts 15- to 20-percent "steady" annual growth through the end of the decade . Racal-Milgo's Schlafly sees the market as growing 35 percent to 40 percent "depending ori the market segment." Frost & Sullivan is equally optimistic, forecasting greater than 35-percent annual growth in dollar value of shipments through 1988, with the fastest market growth toward the end of the period. Over the same period, unit shipments
will increase annually at a greater-than-31-percent rate, the company says.
Data compression, combined with statistical multiplexing, is another technique multiplexer manufacturers are using to boost their products' effective data throughput . " If you can't go to a higher-cost line," stresses Datapro's Jordan , "data compression is one way to squeeze more information onto the line." Chung Communica-

tions' Turbo-MUX-2, for example, employs a proprietary compression technique to support two 2,400-bps, full-duplex channels over one 212A data link. Providing automatic error detection and correction , it supports built-in diagnostics and switchable X-on/X-off flow control.
Compressing text, graphics , facsimile and other data at a 2:1 ratio , the Datamizer from Simplex Communications Corp. doubles the net throughput of a 9.6K-bps line to 19.2K bps, allowing four asynchronous or synchronous devices to share the line. The statistical multiplexer supports both bit-oriented (X.25, SDLC, HDLC) or byte-oriented (binary synchronous 2780, 3780, 3270) protocols.
As traffic densities increase and datacomm networks expand across national boundaries, multiplexers are expanding their capabilities to interface with satellite links, X.25 packet-switching systems and digital T.1 lines , as well as the standard dedicated, private or direct dial system (DDS) lines.
Satellite hookups, however , can present special problems for multiplexers , especially for STDMs using the common GO-BACK-N ARQ error-protection scheme. The transmitting multiplexer stores N frames of data , typically seven, for retransmission should an error occur. However, in satellite links, the round-trip delay frequently exceeds the time it takes to send and acknowledge the seven frames . Multiplexers must therefore be able to handle a sufficient number of unacknowledged frames before considering the transmission to be in error. Codex's

6001 Intelligent Network Processor, for exam_ple, offers variable-length ARQ, where N can be as large as 127. It supports as many as eight asynchronous devices at speeds to 9,600 bps and a synchronous trunk rate to 14.4K bps. Optional integral modems operate at 4,800 or 9,600 bps.
X.25 market expands
Links to X.25 packet-switched communications networks are offered by an increasing number of vendors. "X.25 nets are a growing market area ," comments The Yankee Group's Amster. "According to our data, 70 percent of all people with DECnets [from Digital Equipment Corp.) intend to have X.25 capability by early this year. "
Typical of these multiplexers is Digital Communications Associates Inc. 's INA Terminal Interface Processor. Connecting as many as 32 asynchronous devices and operating to 9.6K bps with a public data network , it supports the three levels of the X.25 protocol. Its X.3 PAD facility interfaces to the network according to Comite Consultatif Internationale Telephone et Telegraphique (CCITT} X.29 standards. Interfacing to character-mode terminals and hosts follows X.28 recommendations. It also provides automatic baud-rate detection, local Echoplex, firmware-based diagnostics and network-management functions .
The X.25 Link Module for the lnfotron Systems Corp. 's 990NP/992NP Network Processor handles as many as 255 channels over a link running at speeds to 72K bps. Either NRZ or NRZl bit-transmission format can be selected. Other X.25-compatible multiplexers include Micom Systems Inc.'s M 800/X.25 PAD, Databit Corp. 's ANP 2520 Advanced Network Processor and General Datacomm Industries Inc.'s 1261.
Satellite links and X.25 interfaces notwithstanding, most of the excitement in the multiplexer arena is focused on links to AT&T Communications' Tl l.544M-bps leased digital line. "Tl multiplexers are a hot market item ," emphasizes Datapro's Jordan. "For a very large firm, they can multiplex a large number of terminals cost-effectively. "
T1 lines slash datacomm costs
"The hottest development in the marketplace today is that all big users are looking at Tl transmission to lower their costs," agrees Timeplex's O'Connor. "Tl gives users the ability to crank both voice and data over the wideband network, eliminating the cost of multiple 9,600or 56,000-bps lines."
"Companies are replacing a multitude of private lines with one Tl circuit," says P. Christensen, president of Tl multiplexer vendor, Aydin Monitor Systems Division, Fort Washington, Pa. "They are less concerned about the cost of the equipment and more worried about the monthly line charges, which cari be rather astronomical. Any money you save on the telephone bill goes right to the bottom line . The incentive is there, the payback is very short, and the cost savings can be dramatic. One large company's [Rockwell International) reduced telephone bill alone will pay for the equipment in only six months. "
Christensen points to users' needs for higher capacity and flexibility as driving forces in the Tl multiplexer market. "The Tl leased line rate was set to be slightly less than the equivalent cost of 24 private circuits," he notes. "Obviously, if you can put more than 24 channels on the line, you

'Stat muxes are going way beyond statistical techniques'
get a large savings." In addition, large firms want the flexibility to be able to run several types of services over wideband lines , Christensen says , including facsimile transm1ss10ns via modem (" very important to large corporations"), efficient hook-ups for computer data circuits , live-action TV conferencing (" without paying the price the phone company charges") and toll-line-quality voice communications.
Good voice quality is crucial
Christensen particularly stresses the importance of quality digitized-voice transmission. " It's crucial not to degrade voice quality as you add services," he says . " In a large corporation , the senior people get rather sensitive when they can't recognize the voice at the other end." The voice quality of acoustic-modem data transfer , for example , is extremely difficult to control. And the complexity of today's large networks can cause further problems when users have to go through a PBX, get a second dial tone and dial again. "A poor modulation scheme will produce distortion ," he warns. " On the other hand , with good modulation , you can modulate/ demodulate five or six times and still have good voice quality."
Not all voice digitization schemes are created equal, Christensen says , and he is particularly critical of the voice quality produced' by multiplexers using continuous variable slope delta (CVSO) modulation schemes. "The technique does not produce a toll-grade voice circuit," he asserts. "You can recognize a man with a rather deep voice . But if you put a woman on , you 've got problems. " This type of equipment, Christensen claims , can only transmit facsimile at 1,200 or 1,400 bps. This contrasts , he says, to the 9,600 bps of Aydin's Model 6296 Tl multiplexer , which uses a variable quantum level (VQL) , 32K-bit , pul se-code-modulation (PCM), voice-digitization technique and supports 48 aggregate channels .
Racal-Milgo 's Omnimux T-1 multiplexer also consolidates multiple voice and data circuits over one high-speed facility . Supporting 48 asynchronous channels to 19.2K bps and as many as 96 synchronous channels to 460.8K bps , it accommodates voice-channel rates to 64 kHz and furnishes centralized network-management and diagnostic capabilites. Channel parameters can be down-line loaded, and the unit is software-configurable from ASCII terminals. The multiplexer also supports synchronous composite transmission at the 2.048M-bps rate available for Tl-type services in European networks.
Another TOM product, Timeplex's LINK/1 Facilities Management System , also offers a composite link to 2.048M bps as well as trafficbalancing capability , automatic alternate routing, dynamic bandwidth contention with programmable port priorities and single-point network control. It handles as many as 200 data ports with data rates to 576K bps.
TOMs, such as the Omnimux or LINK/1 , are superior to statistical TOMs in Tl applications combining voice and data on the digital line , asserts The Yankee Group's Amster. " STDMs are not very good for voice communications," he says , because the STOM is a store-and-forward device that accepts data and puts it on the line in the next available time slot. But the slot might be delayed , and average delays with a heavy traffic load can run to 150 or 250 msec.
" You start getting unacceptable degradation of voice communications with 150-msec delays," Amster says. " Furthermore , if you want to transmit video using an STOM for Tl , you 'll have the same kind of problem. You can't have these random delays." For this reason , in the Tl range at least , " the TOM is coming back in ," he maint a ins .
T1 delay decreasing
Clouding the Tl picture for system integrators and end users is the delay in getting Tl lines, which has been pegged at 24 to 28 months by some analysts. This assessment , however , is con sidered overly pessimistic by sources at AT&T Communications, who say that the situation is finally coming back to normal after the impact of deregulation.
"The normal interval we quote customers is a nine-to-12-month delay for installing a Tl line," stresses Jim Shannon , staff manager of new services development , AT&T Communications, Bedminster , N.J., " and we have been meeting that. As the phone network becomes more digital , and we get all our fiber-optic links in place, the digital service interval should shrink. " Service managers would like to see the wait reduced to six months , Shannon adds, but he doesn't anticipate that happening for a few years.
Definitely in the cards for Tl service, though , is a future American National Standards Institute (ANSI) standard and eventual compliance with international CCITT recommendations. " AT&T is represented on the ANSI Tl Committee ," says Shannon. " We've taken the position that whatever standards come out of that committee , we will adopt as the interim North American standard until our network has clear-chan-

Now up to 128 asynchronous serial communication devices, from as far away as 1,000 feet, can communicate with DEC's* VAX, Q-bus and Unibus* computers.
MDB's new DMF Series Multiplexor was developed because we know systems designers need more efficient ways to control statistical multiplexors, LAN's, dynamic asynchronous terminal line switches and interprocessor links, in the new data communications world.
So from configuration to operation and installation, we've thought of everything to make it possible. Featuring a spacesaving quad sized format, our DMF series is comprised of a host processor board, one or more asynchronous channel boards (A32), and a selection of connector panels.
It means true 128 line capability because terminals can be placed in up to 16 separate clusters anywhere along the 1,000 foot bus and each channel board can control up to a maximum of 32 RS32 terminals running up to 19.2 K baud (38.4 K baud optional).
The host board uses the 29116 ultrahigh performance 16-bit, 100 nanosecond microprocessor, 104 bit wide micro-word, and special logic structures, for the fastest DMF emulation available.
User versatility counts too. The DMF Multiplexor offers such unequalled through-put advantages as the capability to select silo or DMA transfers automatically; and with 16, 18 or 22 bit addressing, the designer can choose the best configuration for the DEC system used . Also , it has its own optimized software drivers for those who have DEC's RSTS/E and RSXll-M+" operating systems.
Now that you can finally use all 128 lines, you may find that you like the bottom line best. All of those technological advances make it the lowest per line cost possible .
Extending the capability of DEC systems is what we're all about. That's why you should contact us immediately with your questions on our new DMF Series Multiplexor or our complete line of DEC compatible system enhancers.

nel capability, at which time we will adopt CCITT standards." Clear-channel capability, Shannon says, permits 64K-bps traffic to be transmitted as 64K bps and not as 56K bps to allow for control bits and other overhead.
Further down the road for Tl multiplexer vendors is the challenge of the proposed worldwide integrated services digital network (ISON). CCITT objectives for ISON include the integration of voice , data , Telex, X .25 and X.21 interfaces , videotex, electronic mail and electronic funds transfer.
A look at tomorrow's products
Whatever the future impact of the ISON on product specifications, multiplexers will continue to offer a wider range of functions, analysts say. Racal-Milgo's Schlafly, for example, sees further progress in network control and diagnostics as well as an extension of the access-control features of high-end products . "Access control is becoming available on modems," she observes. "Perhaps we will see secure multiplexers with encryption features on the aggregate links."
"You are going to see the box containing more
and .more," predicts Amster. "It's going to start
containing protocol conversion and gateway
software as well as a modem. And it's probably
going to have hooks back into network manage-
ment capability ." As multiplexers continue to
integrate functions, Amster says, high-end units
will be increasingly pressured by digital private
branch exchanges (PBXes), which will encroach
on multiplexer functions. "PBXes are starting to
absorb multiplexers and modems and use them
in a shared environment. "
Microprocessors and very large-scale integra-
tion (VLSI) technology will continue to have a
significant impact on multiplexer development ,
Amster says. " We are seeing chip sets for things
that used to take boxes ," he observes. "Multi-
plexers are getting smaller and easier to make.
(Tomorrow's units] will do more features fo r
less ."

UNIX is a registered trademark of AT&T Bell Laboratories.
I I and adds four slots and 20 amps to your host computer. You can daisy-chain two, three, four or more of these units to over 128 channels without using any host power or backplane space!
FREEDOM FOR QBUSTMUSERS.
For LSI-11 systems, the OPTIMUX/64DH exceeds all the capabilities of DEC's DHll.
Occupying just one baGkplane slot on the QBUS, this single, quad-height board expands up to 64 asynchronous communications channels in 16-channel increments.
To prevent loss of received data during high traffic conditions, the 64DH features a switch-selectable 64 or 128character FIFO buffer.
The 64DH is compatible with the standard DHll and DMll drivers contained in the RSX-ll;M RSTS/E®and UNIX®operating systems.
Still another new product for QBUS is the OPTIMUX/8DZ. It multiplexes eight RS232 data channels on a single, dualheight board and is software compatible to the DZll driver.
Isn't it time you proclaimed freedom for y9ur DEC computer systems? For more information on OPTIMUX controllers, call (714) 937-5700. Or write DILOG,

LOCAL AREA NETWORKS
EMERGING STANDARDS TRIGGER $38 LAN MARKET
Finally the software is here that allows LANs to fulfill the promise of shared data
Carl Warren, Western Editor and Rick Dalrymple, Senior Editor
The first flurry of publicity on local area networks (LANs) appeared in 1980. Now, in 1985, LAN sales may actually begin their promised rise to a multibillion dollar market. Early in 1984 , Future Computing of Richardson , Texas, predicted that by 1988 personal computer-LAN sales alone would reach $1.5 billion . But in September, when major developments in networking software were being announced , the market research company revised its forecast for the personal computer segment of the LAN market to predict sales of $3 billion by 1987.
Prior to last year, to paraphrase the old real estate adage, the LAN market lacked three things : standards, standards and standards. This year, the long-awaited standards are finally emerging. Among the "standards" that are losing their quotation marks and becoming officially recognized are Ethernet (IEEE 802.3), tokenpassing bus (IEEE 802.4), token-passing ring (IEEE 802.5) and, in software for PC-LANs, Networks 1.0 from Microsoft Corp., Bellevue, Wash .
"Businesses want to be able to plug any computer into any local area network, like you can plug any lamp into any wall socket without anything blowing up ," points out Amy Wohl , president of Advance Office Concepts, Bala Cynwyd, Pa. Toward that end , LAN vendors are beginning to deliver on their early promises that their products wou ld be a magic link connecting all types and brands of computers .
In 1984, several Ethernet vendors announced networking software that connects the network

user to the operating system of most popular minicomputers and the IBM Corp. PC. With these software packages, an Ethernet user with an IBM PC can communicate with a Digital Equipment Corp. (DEC) VAX as though he were connected directly to that computer with a DEC VTI 00 terminal. The reverse is also possible : A user with a VTI 00 terminal connected to the VAX can access the network and communicate with the IBM PC. The caveat , of course , is that the user must be conversant in the language of the addressed computer and be proficient in operating all those software programs he chooses to call up on the addressed computer.
The new software is a significant step toward linking different computer systems together. For many users ; however, the need for competence in several different operating systems made the

arrangement too complicated. Those users will have to wait until application software developers take advantage of these Ethernet software packages by building application-specific utilities on top of the networking software.
Networking software unlocks the market
Prior to networking software, LAN vendors were trying to sell networking hardware as a solution in itself. During this period only two

kinds of overlapping customers purchased LANs: those who desperately needed the new technology and those who could afford to experiment- hardly the mainstream of potential LAN customers. Now that networking software is beginning to make sharing data and resources practical, market analysts are seeing a bright future for those LAN vendors nimble enough to leverage the emerging standards to their advantage .
Probably none of the recently adopted IEEE network standards will totally dominate the LAN market . So far, the favored standard in scientific and engineering applications is Ethernet-IEEE 802.3. Already compatible with almost all minicomputers, Ethernet's IOMbit- per-second (bps) transmission speed is well suited to the heavy data traffic typically found in scientific and engineering environments.
Early on, Ethernet enjoyed the support of three large corporate backers-DEC, Intel Corp. and Xerox Corp. These corporate backers were joined by the early Ethernet vendors: Advanced Computer Communications, lnterlan Inc. , 3Com Corp. and Ungermann-Bass. Together these firms pioneered the development of Ethernet hardware interfaces. Today many of
the functions these firms first implemented on printed circuit boards are now integrated on a set of silicon chips.
As Ethernet hardware has evolved, network vendors have been able to cut interface costs. Prices for Ethernet interfaces are continuing to fall. According to a forecast from Strategic Inc ., Cupertino, Calif., network interface units will fall in price from around $900 today to less than $400 by 1989. These lower prices , along with an increasing number of application-specific network software utilities, should make Ethernet the network of choice in high-volume data environments.
Token bus automates the factory
Attendees at the June 1984 National Computer Conference (NCC) in Las Vegas saw a demonstration of what probably will be the LAN of the factory-IEEE 802.4 token bus. Six factory automation vendors used the token bus to communicate with automated equipment in a booth sponsored by General Motors Corp. GM is working closely with all token bus network vendors and those firms planning to use the network in factory automation applications, and is clearly· promoting the standard.
Two major features make the token bus more attractive than Ethernet in factory-automation applications. First, the broadband token bus can transmit television signals, allowing the user to see how the robot is responding to instructions sent over the network . This is done over closedcircuit TV cameras and monitors. Second, Ethernet is only able to transmit signals over a distance of about 21/2 kilometers. The token bus is able to transmit signals over much greater distances.
As Ethernet and the token bus were evolving into IEEE standards, a group of people became interested in developing a third standard. This led to the specifications for the token ringIEEE 802.5. The token ring is associated with last year's now-famous IBM LAN nonintroduction . IBM announced that it would not introduce its token-passing ring LAN for at least two years. IBM publicly demonstrated the token-passing baseband ring technology at Telecom '83 in Geneva , Switzerland (MMS, January 1984 , Page 31 ).
According to David Potter , Interlan·s vicepresident of research and development at Westford, Mass., and an Ethernet advocate , " IBM appears to be attempting to differentiate itself from Xerox by the adoption of the token ring... While an IEEE standard does exist , the characteristics and marketplace for the token

ring is presently unclear. What is clear is that any time IBM adopts a standard it generally has a significant impact on the marketplace .
IBM boosts PC-LAN market
Whether by design or accident, IBM has given PC-LAN vendors a much-needed shot in the arm. As with many other computer products, LANs for personal computers need IBM's blessing. With the announcement that the introduction of the IBM token-ring LAN was two years away and that, in the interim, the company would be marketing its PC Network (MMS, October 1984, Page 37), LAN customers were given a better understanding of their networking options.
IBM's PC Network is designed to offer peerto-peer communications in offices and small businesses by joining together combinations of the PC, PC/XT, Portable .Personal Computer and PC-AT . The network links as many as 72 personal computers, enabling them to share information , programs, messages , printers and mass-storage devices. For LAN vendors, however, the most exciting aspect of the PC Network is the software-the PC Network Program which runs under IBM PC-DOS 3.1.
IBM PC-DOS 3.1 is IBM's implementation of Microsoft's MS-DOS 3.1. When IBM an-
nounced its PC Network, Microsoft's Networks 1.0, which runs under MS-DOS 3.1, became an instant industry standard, supported by approximately two dozen computer manufacturers and LAN vendors (MMS, February, Page 47). Microsoft claims that any program written for MS-DOS 3.1 can run under IBM's PC-DOS 3.1 . Microsoft has also announced its own LAN, MS-NET, based on MS-DOS 3.1, but according to 3Com president Bill Krause , " MS-DOS 3.1 is the only significant part of MS-NET because that is the part that IBM is using. "
The key development that excites IBM's competitors is that they do not need to use IBM's LAN hardware because , according to Microsoft , Networks 1.0 is hardware-independent. This means that LAN vendors can substitute their own network board in place of IBM 's and use all the multiuser application software being written for the PC Network operating system. For example, a customer could use one of the network interface boards manufactured by an Ethernet vendor for the IBM PC and link not only IBM PCs (and PC-compatibles) via Ethernet, but also PCs from DEC, Texas Instru ments Inc. or Hewlett-Packard Co., as well as several popular minicomputers. In addition, an Ethernet network could transfer data at speeds up to !OM bits per second (bps) versus the 2M-bps transfer rate
PAD· ····-- wltll · · ......
No longer can the programmable automatic branch exchange (PABX) be dismissed as a fancy telephone switch. Todays PABXes offer all of the telephone functions previously associated with these systems plus some significant new capabilities that make them attractive alternatives to LANs.
One example of the versatility available in the newer PABXes is found in lntecom lnc.'s IBX LANmark. lntecom, Allen, Texas, has been a pioneer in developing high-speed internal packet switching, as opposed to the usual telephone-circuit switching, to transfer data between nodes in a network. lntecom claims its Integrated Business Exchange (IBX) Ethernet LAN can achieve speeds up to 1OM bits per second (bps) over standard twisted-pair telephone wire, thus eliminating the need to install more-expensive coaxial cable.
LANmark Ethernet may be used to extend existing Ethernet systems, to connect many different Ethernets together or to serve as the entire Ethernet connection infrastructure for the different workstations within a system.
The IBX LANmark system provides the capability
for all IBX electronic telephone instruments to attach to Ethernet devices via the 15-pin Ethernet "D" subminiature connector. The electronic telephone instrument routes the information in packets through the IBX to the receiving device, which may be another electronic telephone instrument or a connection to another Ethernet segment. With this scheme, Ethernet workstations may be moved to any location where an IBX telephone jack is installed.
According to Dave Potter, vice-president of research and development at lnterlan Inc., Westford, Mass., a coaxial-based Ethernet vendor, "PABXes make sense for office automation functions such as word processing, electronic mail and electronic calendars, and should coexist peacefully with coaxial-based engineering and scientific-oriented LANs." Most LAN industry observers hold the opinion that the PABX has won a place in the office of the future by virtue of its capabilities alone. By adding data transmission, a PABX can be configured to handle almost any office automation application by exploiting the reach and flexibility of standard telephone wire.

LAN vendors can achieve compatibility for
their network cabling and interface boards
provided their interface and driver software are
implemented up to Layer 4, the transport layer
of the Open Systems Interconnection (OSI) net-
work standard model defined by the Internation-
al Standards Organization (ISO). Microsoft's
group manager for systems product marketing,
Leo Nikora, says LAN vendors may follow
IBM's lead and implement some of the Net-
works 1.0 functions in firmware for faster perfor-
mance.
According to International Data Corp. , Fram-
ingham, Mass., only 15 ,800 PC-LANs were
shipped in 1983, and an estimated 25 ,000 in
1984. These are not impressive numbers consid-
ering the millions of installed PCs but, 1985 may
prove to be the year in which the LAN market-
place finally lives up to its potential.

Now that the local area network (LAN) industry is hooming, some pretty hig names in the computer husiness are jumping on the handwagon. Their goal is simple: get a LAN on the market and let all those who pay homage to The Name run out and huy it.
At Novell, we don't have a hig name to drop when selling etWare, our high-performance LAN operating
system. So we let our technology do the talking. And the network critics are not only listening, they are taking notice.
Performance. No LAN operating
software outperforms NetWare.With speed, Hexibility, security and hundreds of multiuser applications, NetWare sets a standard for the entire LAN industry.
Versatility. NetWare is more than a LAN operating system.
Currently, NetWare software is available for 24 LAN hardware systems. Plus , four complete LAN systems are sold and serviced by Novell.
Compatibility. Because NetWare is compatihle with DOS 3.1, it can
run any application written for the IBM PC Network Program. And NetWare greatly increases IBM PC Network performance and applications software useability.
lnternetworks. Using bridges, etWare can connect separate LAN
systems into one large internetwork. In fact, every LAN Novell supports can be interconnected-any number, in any of the various topologies.
Remember the name. The one LAN system making a big impression on the
network critics is the one with the not-so-hig name: NetWare, from Novell. Remember it when you want a high-performance LAN instead of a high-powered name.

If you 've looked at other data switches then you already know how big and bulky they can be. Some require racks as high as six feet and weigh as much as 600 pounds. And almost all of them need a forklift just to move them about.
But with Emulex's CommXchange you have a lean , compact design. One that can easily be moved around and weighs one sixth as much as those other bulky models.
In fact, the only time other data switches look light-weight next to CommXchange is when you start comparing features and benefits. That's when the CommXchange becomes a heavyweight.
*DEC and VAXcluster are registered trademarks of Digital Equipment Corporation .
NOW, VIRTUALLY ANY nRMINAl CAN ACCESS ANY CPU, PARTICUWLY DEC'S* MINI· COMPUTERS AND VAXCLUmR SYSTEMS. The CommXchange is an advanced , microprocessor-based data switching system designed to let you effortlessly tie together large groups of terminals
to one or more computers. It allows essentially any asynchronous terminal to selectively communicate with a
variety of host computers. This means you can now build on the investment you have already made on existing equipment. You 'll also improve effi-
ciency, since users no longer have to take turns at terminals or waste time going from one office to another to use a terminal dedicated to a particular computer.
REALIZE OPTIMUM TERMINAL SWITCHING FLEllBILITT. A basic CommXchange is capable of routing 360 terminals and computer port lines. Thanks to a port contention feature, there can actually be a larger number of terminals attached to the system than computer ports. This allows the ports to be shared by a number of part-time terminal users, reducing the need to add costly multiplexers as a user's terminal requirements expand .You can add expansion units for an additional 960 lines. And all lines can run simultaneously at speed s up to 9600 bps.

compatible terminal
fit and form.
Our WY-85 gives you complete DEC VT-22ff" software compatibility in function and fit, plus a form that beats all, for a price that beats all.
Like all our terminals, the WY-85 packs all the ergonomic features you want into an unusually small footprint. The generous 14'' non-glare screen tilts, swivels, and handles a full 132-column format. Even the sculpted, low-profile keyboard adjusts for perfect fit and easier function.
So you get not just emulation, but the full operational compatibility you're looking for, including keyboard layout. For a lot less money, in a lot less space, with a lot more style.
No wonder Wyse terminals are now on more than 150,000 desktops worldwide. For more information about our full line of computer display products, call the regional office nearest you.

18 Reasons We're Uniquely
1There's our position on the bottom line. Simply put: No one c:an match our emulations, editing and ergonomics for $549.
Can anyone better this price?
2Only at the expense of features. Often it's obvious where they've cut corners:
With a pug-ugly box. But as you can see, the Ampex 210 is sleekly ergonomic.
3We human-engineered the Ampex 210 with a full 14" screen that tilts and swivels to just the angle you need. So it's comfortable to use, no matter how you're positioned.
7AB well as the local editing and block mode transfer capacities you need to speed work flow.
8Plus 16 resident emulations you can switch at the touch of a key. Including the TeleVideo 910, 910+, 912, 920 or 925~..
9The Lear Siegler ADM 3, ADM 3A, 3A+ or ADM 5~..
13 What's more, we'll add more. In OEM quantities, we'll c:ustomize our 210's appearance, personality and programming so it's perfectly suited to your needs.
14 And if you need a more powerful terminal with even more features, consider the next step up in our family of terminals: the Ampex 230.
15 We back every Ampex terminal with a six month warranty and a worldwide service network.
"TeleVideo, Lea r Siegler, Esprit and Qume are trademarks of TeleVideo Systems Inc; Lea r Siegler Inc; Esprit Systems Inc; and Qume Corporation respecti vely.
Positioned to Meet Your Needs.
4We also equipped it with a low-profile, Selectric-style, adjustable-slope keyboard for easy typing.
5And With a soothing, flicker-free amber screen for easy reading. (If you prefer, you can have the option of green at no extra cost.)
6But ergonomics are just the beginning. The Ampex 210 is as beautifully engineered inside as outside. With line graphics and a bidirectional printer port as standard features.
10 The Esprit (Hazeltine) 1400, 1410 or 1500:..
11 ADDS Regent 20, 25 and Viewpoint.~.
12 And Qume's QVT 102:
16 How can we pack all that into the Ampex 210 for just $549? We're in a position to be competitive. We can take advantage of over 25 years of video, computer peripheral and
offshore manufacturing experience.
17 So if you need a well-designed, full-featured terminal, call us
at 800 621-0292. Or 800 821-9473 in California. We'll show you how you can be very comfortably situated for just $549.

---Never Again Choose .Between
Price and Quality.
The competition says you must sacrifice one for the other. What they're really saying is they can't give you both. Introducing the TeleVideo®921. Proof that low price and high quality do go together.
But don't let its low price fool you. The 921 is years ahead with features taken from our most expensive terminals. Like selectable embedded or non~ embedded field attributes. 32 nonvolatile function keys. 6 fast edit keys. And something we're famous for: in depth support. Including technical assistance, service training and award winning documentation.
One glance at its nonglare amber or green screen with true tilt and swivel. One pass over its low profile, sculptured keyboard. And you know this terminal is built right. In fact, the 921 is built to the highest quality standards in the industry- our own. We use modular subassemblies. All components are pretested and prestressed. Boards are mounted vertically to run cooler, last longer. There's even room to plug in upgrade options. Like our low cost, Tektronix® compatible graphics board.
The point is this. Don't sacrifice either price or qual~ ity. Get both. Get the new TeleVideo 921.

Many manufacturers of networking software
are coming up with "standard" interfaces.
Among these are Novell Inc. , with its Netware software; Applied Intelligence Inc. , with PC-NOS, and Network Research Corp., with Fusion. The Fusion network software works with a number of LANs and operating systems including MS-DOS , UNIX and Digital Equipment Corp. 's VMS. Digital Research Inc. (ORI) has developed a standard Concurrent PC-DOS interface.
Although there may be no true standard interface, most companies planning on implementing networks are excited about the prospect of having device-independent application software.

Networking software has moved up the International Standards Organization model to cover the fourth through the seventh layers . Because of that, application developers can concentrate on the operation of the software rather than on the guts of the network. Industry consultants agree that the application layer will push the acceptance of networks.
Nissan Motor Corp. is developing a sharedresource network based on IBM Corp. PCs. According to a company spokesman, one of the inhibiting factors has been the lack of a consistent way to create applications. Nissan wants to create a series of applications that would be transportable across a range of networks, and they are looking forward to having a common interface from which to work.
File security is important
The use of a network implies a multiuser system and file sharing and therefore the necessity for file security . One difficulty facing software developers is the need to cobble their own methods of file locking and file sharing. " Everyone had their own way of doing things, and that resulted in confusion," says Jean Yates, chairwoman of marketing research firm Yates Ventures, Palo Alto , Calif. Hardware vendors such as AST Research Inc., Corvus Systems Inc. and Western Digital Corp. agree that having a single, common approach to solving interface and filesecurity problems is an important step forward for networks.
Virtually all vendors of network hardware and software agree that very few applications are network-oriented . In most cases, applications are input/output bound-they sit and wait for data input from somewhere, usually a keyboard . This represents a bottleneck because data has to be put into the applications manually , typically moving the data from a remote storage device to the local desktop computer. Flags are set to advise other members of the network that the file is in use and can't be updated until released.
Open system a must
Ian Wallace , director of product support for Applied ComputerTechniques (ACT) Pie., Birmingham, England, contends that having an open software architecture is a must for networking systems. " We are using the Corvus Omninet chipset on a board of our design as the physical layer of our network. We could have used anything since it has to be transparent. What we wanted , and got, was a transportable operating network system from Microsoft with Networks 1.0. It gave us the level of integration we wanted and makes it easy for our value-added resellers (VARs) to add value to our Point 32 system with specialized network applications."
The Microsoft Networks 1.0 is an extension of Microsoft's operating system MS-DOS . The software permits multiple microcomputer systems to share resources . Currently 26 vendors of networking systems, including IBM , have implemented Networks . Some industry observers are

NETWORK SOFTWARE
.._............_.........
With local area networks (LANs) appearing to provide sharing of resources such as disk storage , system integrators face a new problem: how to find the data.
Many of the systems now available, such as Appl ied Compute r Techniques' Apricot Point 32, can support multiple file servers. What's needed in such systems is a conscious effort to manage the data store . Microsoft Corp .'s Leo Nikora says that what is at issue is not technology but rather deciding how to line up the data.
Since most networking software provides some form of device-naming convention (Microsoft's MS-DOS uses full English names) , each file server can be given a specific name. For example, .the file server where word-processing documents will be stored would be called "Document," the one for spreadsheet data, "Financial," and so on . One method of finding a specific piece of data would be asking for a directory of each file server .
Another approach would use a standard device name . Under that approach, /DOCUMENTfTHANKYOU .LTR , would retrieve the "Thankyou .ltr" file from the file server designated " Document. " The slashes (/) denote typical
network convention under MS-DOS or UNIX to define a specific path.
Because most of the newer operating systems, such as IBM Corp.'s PC-DOS and MS-DOS, provide UNIX-like sub-directories in a tree structure under parent directories, the file management problem can become more difficult. But an approach similar to one used to locate a flat file can be executed to find files in hierarchy-based operating systems like PC-DOS or UNIX.
/ DOCUMENT / LETTER / SPECIAL / THANKYOU .LTR , would first find the file server called "Document," then the parent directory " Letter," the sub-directory "Special " and finally the specific file "Thankyou .ltr." The system integrator must decide how to relate the sub-directories to the total system and how to develop a road map for the network users.
The next generation of networking software should provide a better solution to the problem. Network operating systems that automatically locate files by using virtual objects as pointers are expected by late this year. Thus , a user can find any file on any server in any network simply by asking for it.
betting that Microsoft , in co ncert with IBM , has established a de facto standard not only for the overall network operation but also for the integration interface.
The Networks concept is totally hardwareindependent , but the software is dependent on MS-DOS 3. 1. It provides the integration level at the ISO transport interface layer. Networks is designed to establish virtual ci rcuits to the hardware network . Thus, readi ng, writing and error correction are taken care of without intervention on the part of the user or application software.
ACT's Apricot Point 32 system takes advantage of the network ing software. The system permits as many as 10 fi le servers to reside on the system. " We can't limit the network , or the cleverness of the soft ware deve loper. The open architecture means that software can be written that recognizes all the devices on the network and maximizes their usefulness ," says Wallace.
Moving to a higher level
Removing the application programmer fro m the primitives of the hardware and operating system is clearly a benefit . This has been a much-sought-after goal by most system designers , as evidenced by the major industry trends toward standard software interfaces. But Microsoft's Nikora says that providing a common interface just moves the application developer to a higher level and doesn't inhibit his designs.
Strategic's Geddes says that the transport , session and presentation layers are the most
MINI-M ICRO SYSTEMS/Feb ruary 15, 1985
important leve ls of the ISO model. The move to the higher levels of the model are making it easier to handle fi le sharing and security problems. " That's going to have a strong impact on the viabi lity of networks in general," says Geddes . Q uadram's Brown agrees , but he isn' t convi nced that the VAR , user or softwa re developer should be completely restricted fro m the basic operating system altogether. " We don't know exactly what someone will want to do. We should n't inhibit creativity . So we can't hide everything; just make it easier. "
DRI 's president and chief executive officer, John Rowley, says integrators require a consistent architecture, as well as portability of the application. "UN IX and UN IX-like operating system approaches appear to offer a viable solutio n. The key, however, isn 't necessarily the actual operating system , but rather a consistent interface approach."
Nikora and Brown warn that licensing may be a problem. Typically, single-user application software is licensed to one machine. If it is put on a fi le server for use by many users, it can violate the license. To get around this , companies such as Ashton-Tate , and Probase Group , are offering network versions of their database products that provide the required license, as
well as file lockouts and sharing semaphores. D

VOICE-DATA COMPUTERS/TERMINALS
VOICE-DATA INTEGRATION ENTERS WAR FOR DESKTOPS
Telephone, computer and terminal manufacturers try a new mix of product capabilities to secure larger shares
of the office-automation marketplace
Jerry Borrell, Senior Western Editor
The desktop represents the battleground for vendors seeking a share of the office-automation marketplace. Until recently, firms within the computer and telephone industries competed separately. However, as each industry reached for the technology of the other, rivalry between them increased dramatically. In addition, this merging of communication and computer technology has created a new product market. The result? Integrated voice-data (IVD) products are now appearing as fierce competitors to dedicated terminals and personal computers.
Greg Carlsted , industry analyst for Dataquest Inc., San Jose , Calif. , contends that IVD shipments will expand from 100,000 units in 1984 to around one million units in 1988.
As expected, each industry brings its own approach to the integration of voice and data. However, all manufacturers seek to unite telephone features (auto-dialing, electronic messaging and voice communication) and terminal functions (alphanumeric display, database access) with personal computer operations (word processing, spreadsheets) . Consequently four categories for the IVD market have emerged: integrated voice-data terminals, voice-data terminals with local processing, additions to existing computers and private branch exchange (PBX) products. Although each category has its
MINI-MICRO SYSTEMS/February 15, 1985

SOURCE: DATAQUEST
champions, industry analysts suggest that the acquisition of Rolm Corp. by IBM Corp. has positioned IBM to move into any or all of the categories . Major market targeted
Each of the categories has a market niche, but it is difficult for system integrators to choose which features to build into their IVD products when the market is still largely undefined. Jack Conroy, chief executive officer at Santa Barbara Laboratories Inc., Santa Barbara, Calif., says

VOICE-DATA COMPUTERS/TERMINALS
Add-on products represent the market with the greatest potential for fast, near-term growth.
300,000 office executives represent one target audience for IVD products. Another is the "knowledge worker," estimated to include 60 percent of all employed people in the United States. Specific job categories in this market include clerical workers who use terminals for data entry, airline employees who require programmable functions, professionals in medicine and law and specialists in finance and brokerage who require local processing as well as terminal functions.
Phone features desired
Some IVD manufacturers enjoy a market among users desiring access to a database, or among those who use an electronic calendar or electronic mail. These applications suit real estate, finance, banking and brokerage markets.
IVD vendors, then, offer such electronic telephone features as auto-dialing, memory, conferencing and a wide range of ASCII terminal emulation. Phone manufacturers dominate this market segment, but terminal manufacturers, notably Liberty Electronics USA, San Francisco, Calif., and TeleVideo Systems Inc., Sunnyvale, Calif., have established a presence.
Eventually, every phone owner will be offered IVD capabilities. The more-than-100-million phones installed in the United States represent a lucrative IVD market for voice-data technology .
Richard Larson, vice president for sales at Matra Communications Inc., Cupertino, Calif., thinks that, " IVD terminals are not suited for commodity-market competition because they require some software adaptation for specific users. " Matra focuses on value-added-resale markets in areas such as real estate, finance, banking, brokerage and electronic mail.
Laura J. Peck , senior analyst at L.F. Rothschild, Unterberg, Towbin and Co., San Francisco, is less than sanguine about the IVD market. She points out the likelihood of "price erosion, particularly for terminal products, occurring as functionality increases." The result is likely to be the cutthroat pricing practices that affect terminal markets.
Save money with add-on products
According to industry analysts, add-on products represent the market with the greatest potential for fast, near-term growth. Manufacturers cite the large installed base of IBM PCs as having lucrative potential for add-on telephony and data-function units.
The strength of the add-on market is found, according to Charles Foskett, president of Natural MicroSystems Corp., Natick , Mass., "in the knowledge-based industries that are communications-intensive. As much as 50 percent of the small businesses in the United States fit this

Of the five companies currently selling com- There are advantages and disadvantages to this

approach. Rolm's Harr summarizes the benefits to buyers. "The first advantage is speed. With proprietary software, we can transmit data over twisted pair at rates to 19.2K baud. When corporate users want to access a central database , the advantage of a high transmission rate is obvious .
The second advantage relates to the mainframe . When 20 users want to access five ports on the mainframe, the PBX can handle all the queuing. Finally , by using proprietary software , we can use one twisted pair and offer not only voice and data but also PBX functions such as call parking, hold , transfer and speedcall. "
The PBX functions can be sufficient reason for purchasing a vendor-proprietary system. The cost of installing two telephone lines to allow simultaneous voice and data on terminal-based products might be more expensive than the cost of PBX systems for large-user environments.
Amy Smith of The Yankee Group is bullish on system integrators competing in this segment. "At some point , all the IYO products are associated with the PBX, and the most functionality is offered when these two share a common interface. Manufacturers such as Zaisan , which have generic products, will have to make OEM deals with PBX vendors to compete in the long run. This is true because of the need for performance features tied to the PBX."
Caution advised
Nevertheless, OEMs and large-volume end users must consider this option carefully. By integrating IYO equipment tied to a PBX, they are constrained to use only those IYO products compatible with the PBX's software. Also , system integrators tie their fortunes to the fortunes of a chosen PBX vendor.
Although Honeywell Inc ., Minneapolis , Minn ., and Rolm have an early lead in developing IYO devices for proprietary PBXes, two other companies, Davox Corp., Billerica , Mass. , and Sydis Inc., San Jose, Calif. , are the first companies to supply multiuser IYO systems. Davox chose to provide IYO for the IBM 3270 marketplace . Deirdre Searles , director of marketing for Davox, divides the IYO market into two classes: " ... one for high-speed synchronous products , such as those from IBM , and one for asynchronous environments , which must use protocol converters. The asynchronous market is more appropriate for executive workstations , such as those from Zaisan. "
Davox expects to have more than one million units in the synchronous 3270 market by 1988 with its IYO terminal and its multiuser , minicomputer network facility called DavoxNet. It is
in large-user networks, says Searles , " that Davox offers the greatest advantage. The new Cedar product from Rolm , for example, costs about $5 ,000 , whereas our system in a multiuser environment can bring the individual terminal cost down to $2 ,500." Davox also allows the system to be configured over existing twisted-

pair phone connections.
Sydis has chosen a proprietary multiuser co m-
puter system for its voice-data products . Accord-
ing to Ken Gilbert, director of product market-
ing , Sydis sells multiuser computers to the
management information systems market . Part
of the impetus for this market , says G ilbert ,
" was given by the IBM PC. As they went into
office environments , users began to connect the
PC to the IBM mainframe , demanding CPU
time and forcing the MIS group to find indepen-
dent supporting computers to offload the host ."
The Sydis product performs this work in additio n
to offering the user IYO capability.
The Sydis multiuser computer works with the
customer's existing analog PBX. Gilbert explains
that, " 85 to 90 percent of existing PBX equip-
ment is analog . Sydis offers an advantage to all
PBX owners , allowing them to retain their cur-
rent systems for five to seven more years , rather
than forcing them to add digital PBX equipment
to obtain an IYO- system ."

Row To Delight Your Lotus
With Mainframe Data
Another Smart Solution From AVATAR
The idea is simple. Make yo ur PC spreadsheet even more powerful by giving it mainframe data. But getting that data out of your mainframe, into your PC and onto yo ur spreadsheet isn 't that simple.
Until now, you've had three choices. Transfer entire fi les from the host and risk choking your PC with data. Not very efficient. Or find the information in printed reports, then reenter and reformat it. Very tedious. And the alternative of asking your DP department to write special host software ... well, they're overburdened already: Three choices , no real solution.
Now there's TURBO, the newest micro-to-mainframe link from AVATAR.
TURBO 's Data Capture lets
yo u select just the information you need from the mainframe. And use it immediately in any of your PC applications- Lotus, dBASE , you name it. Without rekeying, reformatting , re-anything.
And you can use TURBO's host-assisted File Transfer the way file transfer was meant to be used- for sharing data with other PC users on the 3270 netwo rk.
If that isn't enough , TURBO 's exclusive Macro Language adds a whole new dimension to your micro-to-mainframe link. Use Macros to automate file transfer and data capture. Better yet , massage host data even before feeding it to your spreadsheet.
So give your PC a TURBO from AVATAR. And delight your Lotus with mainframe data.

How To Triple The Speed OfYour 3270 Printer
A nother Smart Solution From AVATAR
It's a sad sight. Seeing your IBM 3270 printer falling further behind every day. Outpaced by ASCII printers that deliver far greater performance at a much lower cost. ASCII printers that, until now, didn't link to your 3270 system.
Enter AVATAR's PA1500 protocol converter. It lets you attach virtually any ASCII printer directly to your 3270 network with a simple coax connection including printers that are three times as fast as your IBM printer and cost half as much. ·
Now you can select the printer that matches your system needs. For greater speed, letter quality printing, better performance. Fast dot matrix or line printers. Bar code or graphics printers. Even the newest ink jet or laser printers can be a part of your 3270 network.
Together, the PA1500 and the printer of your choice give you all the capabilities of your IBM printer... and more.
So get yourself an AVATAR PA1500. And bring your 3270 printer up to speed.
