Calix E7-2 AXOS GE-24 r2

As next-generation Ethernet services gain momentum in the marketplace and begin to extend out from the metropolitan area networks, they will drive demand for versatile, cost-effective aggregation out at the network edge. Aggregation solutions increase services scalability and improve time to market. As North America’s most widely deployed access system, the Calix AXOS E7-2 Intelligent Modular System is a breakthrough evolutionary system that provides a transformational path to next-generation networks, fiber technologies, and Software Defined Access. The E7-2 is the industry’s benchmark for a modular, small form factor, environmentally hardened access solution for service providers. By adding the AXOS platform, the E7-2 is now even more of a disruptive and compelling enabler to next-generation networks that connect the world. The AXOS E7-2 leads a rapidly expanding family of AXOS E-Series systems capable of supporting both centralized and decentralized network architectures that range from the data center edge, central office, or headend, to the remote cabinet, or MDU.

Functional Description

POINT-TO-POINT ETHERNET

Point-to-point Ethernet, or Active Ethernet (AE), is a complementary network design to point-to-multipoint GPON access networks. With point-to-point Ethernet, network operators can provide individual subscribers with very high-bandwidth, dedicated symmetric services utilizing a fiber network that is flexible and simple to design.

Key Features and Capabilities

The Calix E7-2 AXOS GE-24 r2 card provides multiservice capability over IP/Ethernet-based networks. Each GE-24 r2 card provides 24 GE ports and can be paired to aggregate up to 48 point-to-point Ethernet ONT subscribers per 1RU E7-2 chassis. The E7-2's modular chassis design allows equipping the system with twenty GE-24 r2 cards, to aggregate up to 480 Calix 700GX/700GE ONTs or Calix 844GE ONTs. GE interfaces on the GE-24 r2 card can also be used to provide point-to-point and ring-protected aggregation of GE-capable network devices. The GE-24 r2 is compatible with other E7-2 AXOS line cards.

IP Services Delivery

In conjunction with the Calix family of Active Ethernet ONTs, the E7-2 GE-24 r2 card delivers a full spectrum of access services over point-to-point Ethernet networks.

• IPTV – broadcast and Video on Demand (VoD)
• MEF compliant business services
• High-Speed Internet (HSI) access
• Voice – Native SIP/VoIP and TDM Gateway support
• T1 business services and Mobile Backhaul access

Integrated High-Capacity Transport

Built on a core Layer 2 and Layer 3 switch, the E7-2 AXOS GE-24 r2 line card is capable of full-duplex, line-rate forwarding at all frame sizes and traffic types across all interfaces. Each PON port has a dedicated 10 Gbps switch interface. Two 10 GE XFP and two 10GE SFP+ uplinks provide support for backhaul of all traffic.

Network Resiliency

The Calix E7-2 AXOS GE-24 r2 line card supports a flexible set of standards-based network topology protocols for use in point-to-point or ring-based transport.

Supported protocols include:

• ITU G.8032v2 Ethernet Ring Protection Switching (ERPS)
• IEEE 802.1w Rapid Spanning Tree Protocol (RSTP)
• IEEE 802.3ad/802.1AX Link Aggregation

Double-Density Optics Modules

Industry-standard pluggable modules are used for all E7-2 service and network interfaces. The GE-24 r2 supports CSFP (Compact SFP) modules that are mechanically compatible with the industry-ubiquitous SFP module. Each CSFP module supports two independent bidirectional transceivers (1490nm Tx / 1310nm Rx), each capable of operating at a 1 Gbps bi-directional rate.

The E7-2 GE-24 r2 card is compatible with CSFP Option 2 modules. Option 2 of the CSFP Multisource Agreement (MSA) was released in October 2009 and provides backward compatibility to the SFP MSA. As a result, the GE-24 R2 can operate with single-port SFP modules in any of the 12 CSFP module sockets to reach more distant locations. High-density, dual-port CSFP modules have a maximum range of 40km, while single-port SFPs can be used to reach AE ONTs and Ethernet Service Access Nodes up to 60 km distant.

The GE-24 r2's 10GE SFP+ ports support all GE SFP modules, extending the versatility of the SFP+ ports to provide additional GE services or GE transport flexibility.

Scalable IPTV Support

The Calix E7-2 AXOS GE-24 r2 card supports IGMP Snooping for multicast video transport between the set-top box and multicast router, providing efficient, scalable, high-quality IPTV distribution on all Ethernet interfaces.
