I-SAToP Emulation ku-T1 kanye ne-E1 Interfaces Overview
I-Structure-Agnostic time-division multiplexing (TDM) phezu kwePhakethi (SAToP), njengoba kuchazwe ku-RFC 4553, Structure-Agnostic TDM over Packet (SAToP) isekelwa kumarutha e-ACX Series Universal Metro anezixhumi ezibonakalayo ze-T1 ne-E1 eyakhelwe ngaphakathi. I-SAToP isetshenziselwa i-pseudowire encapsulation yamabhithi e-TDM (T1, E1). I-encapsulation ishaya indiva noma isiphi isakhiwo esibekwe ekusakazweni kwe-T1 ne-E1, ikakhulukazi isakhiwo esibekwe uhlaka olujwayelekile lwe-TDM. I-SAToP isetshenziswa phezu kwamanethiwekhi ashintshiwe ephaketheni, lapho amarutha onqenqema lomhlinzeki (PE) engadingi ukutolika idatha ye-TDM noma abambe iqhaza ekusayineni kwe-TDM.
QAPHELA: Amarutha e-ACX5048 kanye ne-ACX5096 awawasekeli i-SAToP.

Umfanekiso wesi-5 ekhasini lama-41 ukhombisa inethiwekhi eshintshwa ngephakethe (PSN) lapho amarutha amabili e-PE (PE1 kanye ne-PE2) ehlinzeka nge-pseudowires eyodwa noma ngaphezulu kumarutha onqenqema lwamakhasimende (CE) (CE1 kanye ne-CE2), asungula umhubhe we-PSN wokuhlinzeka ngedatha. indlela ye-pseudowire.

Ukuhlukaniswa kwesikhathi kwesakhiwo okuqaphelayo i-multiplexed (TDM) Isevisi Yokulingisa Yesifunda nge-Packet-Switched Network (CESoPSN) iyindlela yokuhlanganisa amasiginali e-TDM emaphaketheni e-CESoPSN, futhi ngokubuyela emuva, kunqanyulwa amaphakethe e-CESoPSN abuyele kumasiginali we-TDM. Le ndlela ibizwa nangokuthi i-Interworking Function (IWF). Izici ezilandelayo ze-CESoPSN zisekelwa kuJuniper Networks ACX Series Universal Metro Routers:
Ukwenziwa kwesiteshi kuze kufike ezingeni le-DS0
Izinombolo ezilandelayo zama-pseudowires e-NxDS0 zisekelwe kumachweba akhelwe ngaphakathi angu-16 T1 kanye ne-E1 kanye nezimbobo ezakhelwe ngaphakathi ezingu-8 T1 kanye ne-E1, lapho i-N imele izikhala zesikhathi ezimbobeni ezakhelwe ngaphakathi i-T1 ne-E1. I-16 T1 kanye ne-E1 eyakhelwe ngaphakathi isekela inombolo elandelayo yama-pseudowires: · Imbobo ngayinye ye-T1 ingaba nama-pseudowires angu-24 e-NxDS0, ahlanganisa isamba esingafika ku-384 NxDS0
ama-pseudowires. · Imbobo ngayinye ye-E1 ingaba nama-pseudowires angu-31 e-NxDS0, ahlanganisa isamba esingafika ku-496 NxDS0
ama-pseudowires. Izimbobo ze-8 T1 kanye ne-E1 ezakhelwe ngaphakathi zisekela inombolo elandelayo yama-pseudowires: · Imbobo ngayinye ye-T1 ingaba nama-pseudowires angu-24 e-NxDS0, ahlanganisa isamba esingafika ku-192 NxDS0
ama-pseudowires.

· Imbobo ngayinye ye-E1 ingaba nama-pseudowires angu-31 e-NxDS0, ahlanganisa isamba esingafika ku-248 NxDS0 pseudowires.
Ukusekela Iphrothokholi Zonke izimiso eziyisisekelo ezisekela i-Structure-Agnostic TDM over Packet (SAToP) zisekela i-CESoPSN NxDS0 interface.
Ukubambezeleka Kwephakethe Isikhathi esidingekayo ukuze udale amaphakethe (kusuka ku-1000 kuya ku-8000 microsecond).
CESoPSN Encapsulation Lezi zitatimende ezilandelayo zisekelwa ezingeni [edit interfaces interface-igama] isigaba: · ct1-x/y/z partition partition-number timeslots timeslots interface-type ds · ds-x/y/z:n encapsulation cesopsn
Izinketho ze-CESoPSN Izitatimende ezilandelayo zisekelwa ezingeni [edit interfaces interface-name cesopsn-options] isigaba sokulandelana: · overive-packet-loss-rate (s)ampi-le-period millisecond) · iphethini ye-idle-pattern · i-jitter-buffer-latency millisecond · amaphakethe we-jitter-buffer-packets · ama-packetization-latency microseconds
khombisa Imiyalo I-interface yombukiso-igama umyalo obanzi usekelwa i-t1, i-e1, kanye nezindawo zokusebenzelana.
I-CESoPSN Pseudowires CESoPSN pseudowires imisiwe ku-interface enengqondo, hhayi esibonakalayo esibonakalayo. Ngakho isitatimende seyunithi enengqondo-yeyunithi-yenombolo kufanele sifakwe ekucushweni ezingeni [hlela i-interfaces-igama] izinga lokulandelana. Uma uhlanganisa isitatimende seyunithi yeyunithi enengqondo, i-circuit cross-connect (CCC) yesixhumi esibonakalayo esinengqondo sidalwa ngokuzenzakalelayo.

Ukuze uxoxisane phakathi kwendawo yokuthunga kanye namaphoyinti okugcina wesifunda, udinga ukulungisa izinketho ezilandelayo.
· Izinga-lokulahlekelwa-iphakethe-setha izinketho zokulahlekelwa kwephakethe. Izinketho ziyi-sample-period kanye nomkhawulo. · sampi-le-period–Isikhathi esidingekayo ukuze kubalwe izinga lokulahlekelwa kwephakethe elidlulele (kusuka ku-1000 kuya ku-65,535 millisecond). · i-threshold–Percentile echaza umkhawulo wezinga lokulahlekelwa kwephakethe elidlulele (amaphesenti angu-1).
· i-idle-pattern–Iphethini engu-8-bit hexadecimal yokushintsha idatha ye-TDM ephaketheni elilahlekile (kusuka ku-0 kuye ku-255).
· I-jitter-buffer-latency–Isikhathi sokubambezeleka kubhafa ye-jitter (kusuka ku-1 ukuya ku-1000 millisecond). · jitter-buffer-packets–Inani lamaphakethe kubhafa ye-jitter (kusuka kuphakethe eli-1 kuye ku-64). · i-packetization-latency–Isikhathi esidingekayo ukuze udale amaphakethe (kusuka ku-1000 kuya ku-8000 microsecond). · Usayizi womthwalo okhokhelwayo–Usayizi wokukhokha wamasekhethi abonakalayo aphela ku-Layer 2 interworking (iw) okunengqondo
