Uhlolojikelele

Idivayisi esebenzisa ubuchwepheshe bokuphindaphinda kwesiqondisindlela ukuze inqwabelane kumasekhethi amaningi e-E1 ukuze idlulisele idatha ye-Ethernet ye-4Channel 100BASE-TX.Ingabona ukuguqulwa phakathi kwesiteshi esingu-1~8 se-E1 nesixhumi esibonakalayo se-Ethernet, ukwenza iziteshi ze-E1 zixhunywe ne-Ethernet optical interface.Usebenzisa i-GFP encapsulation, sekela i-LCS (isikimu sokulungiswa komthamo wesixhumanisi) kanye nephrothokholi ye-LAPS.

Le divayisi ingakwazi ukusekela ukumiswa kwesiteshi se-1-8 Channel E1, ingathola ngokuzenzakalelayo inombolo ye-E1 bese ikhetha i-E1 etholakalayo.Ivumela i-E1 imigqa yokudlulisa isikhathi, 1channel/4channel/8channel Ethernet bandwidth is1984Kbit/s, 7936Kbit/s, 15872 Kbit/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.

• Ukudluliswa okusobala kwedatha ye-Ethernet kumasekethe angu-1 kuya kwangu-8 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-8-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 ejwayelekile 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;
• Lapho umkhawulokudonsa wokudlulisela ukhuphuka, ngeke kulimaze idatha ye-Ethernet;umkhawulokudonsa wokudlulisela uncishisiwe ngokwenziwa, futhi ungabonakala ngaphandle kokulimaza inethiwekhi yedatha ye-Ethernet;
• I-E1 tributary ends ingase ingahambelani nokuxhumeka kwe-serial;
• Uma i-slip direction E1 ihluleka, enye indlela isengasebenza;
• Iluphu yesignali ye-E1 ibuyele emuva futhi inqamule umsebenzi wokuthola okuzenzakalelayo: Lapho ithola ukwenzeka kweluphu yesiginali ye-E1 yomgwaqo, isistimu inqamule le E1;i-loopback ikhishiwe, i-E1 yokutakula okuzenzakalelayo sebenzisa lo mgwaqo;
• Gcwalisa inkomba ye-alamu, khetha ukubonisa i-alamu yendawo / ekude;
• Isekela umugqa we-loopback ohlangothini lwe-E1 ukuze kube lula ukuhlolwa kwemigqa ye-E1;
• Sekela isistimu yendawo yokusetha kabusha isistimu yesilawuli kude;
• hlinzeka ngomyalo we-loopback esibonakalayo esikude, ukugcinwa kalula komugqa;
