Uhlu Lwamanani Ashibhile lwe-2m Ukuguqulwa kwe-V24 - 16E1 kuya ku-4FE GFP isixhumi esibonakalayo Isiguquli se-JHA-CE16F4 – JHA

16E1 ukuze 4FE GFP isikhombimsebenzisi Converter I-JHA-CE16F4

Uhlolojikelele

Idivayisi esebenzisa ubuchwepheshe bokuphinda ibuyele emuva ukuze ihlanganise amasekhethi e-E1 amaningi ukuze idlulisele idatha ye-Ethernet ye-4Channel 100BASE-TX. Ingakwazi ukubona ukuguqulwa phakathi kwesiteshi esingu-1~16 se-E1 nesixhumi esibonakalayo se-Ethernet, ukuze yenze amashaneli e-E1 axhumeke nesixhumi esibonakalayo se-Ethernet. Usebenzisa i-GFP encapsulation, sekela i-LCS (isikimu sokulungiswa komthamo wesixhumanisi) kanye nephrothokholi ye-LAPS.

Lolu cingo lungasekela ukucushwa kwesiteshi se-1-16Channel E1, lukwazi ukubona ngokuzenzakalelayo inombolo ye-E1 bese lukhetha i-E1 etholakalayo. Ivumela i-E1 imigqa yokudlulisa isikhathi, 1channel/4channel/8channel/16channel Ethernet bandwidth is1984Kbit/s, 7936Kbit/s, 15872 Kbit/s,31744Kbit/s.
Idivayisi inikeza umsebenzi we-alamu. Umsebenzi unokwethenjelwa futhi uphansi ukusetshenziswa kwamandla, ukuhlanganiswa okuphezulu, usayizi omncane. Ukuphathwa Kwenethiwekhi Yokusekela , Umsebenzi oyinhloko wohlelo lokuphatha inethiwekhi ukugcwalisa uphenyo lwamadivayisi asendaweni nakude kanye nokuphathwa kokucushwa okuhlanganisa nombuzo wesimo se-alamu kulayini we-E1, isimo sokusebenza se-Ethernet, nokulawula i-loopback njll.

Izici

• Ukudluliswa okusobala kwedatha ye-Ethernet kumasekethe angu-1 kuya kwangu-16 E1;
• Ingafakwa isixhumi esibonakalayo sikagesi esishintshayo se-Ethernet ukuze umsebenzisi alondoloze iswishi ye-Ethernet;
• I-Ethernet 10/100M, i-duplex egcwele/uhhafu iguquguquka ngokugcwele, isekela iphrothokholi ye-VLAN;
• Ichweba ngalinye lisekela i-Ethernet i-AUTO-MDIX (ikhebula le-crossover kanye nokujwayela komugqa oqondile);
• Isixhumi esibonakalayo se-Ethernet futhi siyizixhumi ezibonakalayo ozikhethela ukuze kuzuzwe ukudluliswa kwedatha ye-Ethernet ngokuxhumanisa i-E1 kude;
• Imigqa engu-16-channel E1, umehluko omkhulu wokulibaziseka phakathi kwanoma yikuphi okubili ungafinyelela ku-220ms; lapho umehluko wokulibaziseka ungaphezu kuka-220ms, ukubambezeleka kuzoveza i-alamu engalungile, kuyilapho ukuphazamiseka kwebhizinisi;
• Uhlu lwamakheli we-Ethernet MAC olwakhiwe (4096), olunomsebenzi wokuhlunga uhlaka lwedatha yendawo;
• I-E1 interface ithobela i-ITU-T G.703, G.704 ne-G.823, ayisekeli ukusetshenziswa kwezikhala zokusayina;
• Imodi yesibali sikhathi, isikhathi esikhethwayo sendawo kanye nokulandelela isikhathi somugqa we-E1, umthombo wesikhathi womugqa we-E1 ungashintshwa ngokuzenzakalela ngokuya ngekhwalithi yesiginali. Njengesistimu yomthombo wesikhathi womugqa we-E1 womgwaqo wokuqala u-E1, lapho ukwehluleka kwe-E1 yokuqala (isixwayiso esibucayi i-LOS/AIS/LOF/CRC4 noma i-loopback ekhiqiza isignali) kanye nendlela yesibili engu-E1 isebenza kahle, isistimu izoshintshela ethrekhi ngokuzenzakalelayo. Umgwaqo wesibili E1; ukuqedwa kwephutha, uhlelo bese lubuyela ngokuzenzakalelayo kumgwaqo wokuqala we-E1;
• Ukuhambisana nephrothokholi evamile ye-ITU-T, isiphakamiso se-GFP-F encapsulation G.7041, VCAT concatenation virtual kanye LCAS Link Capacity Adjustment izincomo G.7042, Ethernet mapping kuya nxE1 isincomo G.7043, Ethernet ku-E1 isiphakamiso semephu eyodwa G. 8040;
