Txheej txheem cej luam

Cov cuab yeej siv rov qab kev taw qhia multiplexing thev naus laus zis los ntim rau ntau E1 kom xa cov ntaub ntawv Ethernet ntawm 3Channel 1000BASE-TX thiab 2x1000Base-X. Nws tuaj yeem paub txog 1 ~ 16 E1 hloov pauv ntawm Ethernet kho qhov muag interface, ua rau E1 raws kev sib txuas nrog Ethernet optical interface. Siv GFP encapsulation, txhawb LCAS (txuas kev hloov kho lub peev xwm) thiab LAPS raws tu qauv. cov cuab yeej no tuaj yeem txhawb nqa 1-16Channel E1 channel teeb tsa, tuaj yeem ntes tus lej E1 thiab xaiv E1 muaj. Nws tso cai rau E1 kab sib kis lub sijhawm, ib kab tus nqi yog 1984Kbit / s, 4channe Ethernet bandwidth yog 7936Kbit / s, 8channel bandwidth yog 15872 Kbit / s, 16channel bandwidth tuaj yeem ncav cuag 31744Kbit / s.
Cov cuab yeej muab lub tswb muaj nuj nqi. Kev ua haujlwm yog txhim khu kev qha, ruaj khov, thiab kev siv hluav taws xob tsawg, kev sib koom ua ke siab, me me. Txhawb SNMP Network tswj.

• 16-channel E1 kab, qhov siab tshaj plaws ncua sij hawm sib txawv ntawm ib qho twg tuaj yeem ncav cuag 220ms; thaum qhov ncua sij hawm sib txawv tshaj 220ms, qhov ncua sij hawm yuav ua rau lub tswb tsis zoo, thaum kev lag luam cuam tshuam;
• Ua dynamic Ethernet MAC chaw nyob daim ntawv teev npe (4096), nrog rau cov ntaub ntawv hauv zos thav duab lim dej muaj nuj nqi;
• E1 interface ua raws li ITU-T G.703, G.704 thiab G.823, tsis txhawb kev siv cov teeb liab qhov chaw;
• Timer hom, xaiv lub sijhawm hauv zos thiab taug qab E1 kab sijhawm, E1 kab sijhawm tuaj yeem hloov pauv raws li lub teeb liab zoo. Xws li E1 kab lub sij hawm qhov system rau thawj Txoj Kev E1, thaum thawj E1 tsis ua hauj lwm (kev ceeb toom loj LOS / AIS / LOF / CRC4 los yog lub teeb liab generating loopback) thiab txoj kev thib ob E1 ua haujlwm zoo, lub kaw lus yuav hloov mus rau txoj kev khiav. Txoj kev thib ob E1; tshem tawm qhov txhaum, lub kaw lus cia li rov qab mus rau txoj kev thawj txoj kev E1;
• Ua raws li ITU-T tus qauv raws tu qauv, GFP-F encapsulation suggestion G.7041, VCAT virtual concatenation thiab LCAS Link Capacity Adjustment pom zoo G.7042, Ethernet mapping rau nxE1 kev pom zoo G.7043, Ethernet rau ib E1 daim ntawv qhia kev pom zoo G. 8040;
• Thaum kis tau tus mob bandwidth nce, yuav tsis ua rau cov ntaub ntawv Ethernet puas; Kev xa tawm bandwidth yog txo qis, nws kuj tuaj yeem ua tiav yam tsis muaj kev puas tsuaj rau Ethernet cov ntaub ntawv network;
• E1 tributary Ø kawg yuav tsis sib xws los ntawm kev sib txuas serial;
