Txheej txheem cej luam

Cov cuab yeej siv rov qab kev taw qhia multiplexing thev naus laus zis los ntim rau ntau E1 circuits kom xa cov ntaub ntawv Ethernet ntawm 4Channel 100BASE-TX. Nws tuaj yeem paub txog kev hloov pauv ntawm 1 ~ 8 channel E1 thiab Ethernet optical 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 1-8 Channel E1 channel teeb tsa, tuaj yeem ntes tus lej E1 thiab xaiv E1 muaj. Nws tso cai rau E1 kab sib kis lub sijhawm, 1channel / 4channel / 8channel Ethernet bandwidth is1984Kbit / s, 7936Kbit / s, 15872 Kbit / s.
Cov cuab yeej muab lub tswb muaj nuj nqi. Kev ua haujlwm yog txhim khu kev qha thiab kev siv hluav taws xob tsawg, kev sib koom ua ke siab, me me. Txhawb Kev Tswj Xyuas Network, Lub luag haujlwm tseem ceeb ntawm kev tswj hwm lub network yog ua kom tiav cov lus nug rau cov khoom siv hauv zos thiab cov chaw taws teeb thiab kev tswj xyuas kev teeb tsa nrog rau kev nug ntawm lub tswb xwm txheej ntawm E1 kab, Ethernet ua haujlwm raws li txoj cai, thiab kev tswj xyuas loopback thiab lwm yam.

Nta

• Transparent kis ntawm Ethernet cov ntaub ntawv hauv 1 txog 8 E1 circuits;
• Yuav nruab nrog plaub Ethernet hloov hluav taws xob interface rau cov neeg siv kom txuag tau Ethernet hloov;
• Ethernet 10/100M, tag nrho / ib nrab duplex siab hloov kho, txhawb VLAN raws tu qauv;
• Txhua qhov chaw nres nkoj txhawb Ethernet txhawb AUTO-MDIX (crossover cable thiab ncaj-kab adaptation);
• Ethernet interface kuj yog qhov kev xaiv kho qhov muag interfaces kom ua tiav cov ntaub ntawv kho qhov muag Ethernet kis tau los ntawm kev sib tshuam E1 deb;
• 8-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 hnyav LOS / AIS / LOF / CRC4 los yog 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 kawg yuav tsis sib xws los ntawm kev sib txuas serial;
• Thaum ib qho kev taw qhia E1 tsis ua haujlwm, lwm qhov kev taw qhia tseem tuaj yeem ua haujlwm;
• E1 teeb liab voj rov qab thiab txiav tawm qhov tsis siv neeg tshawb pom muaj nuj nqi: Thaum kuaj pom qhov tshwm sim ntawm txoj kev E1 teeb liab voj, lub kaw lus txiav tawm E1 no; loopback tso tawm, E1 tsis siv neeg rov qab siv txoj kev no;
• Ua tiav lub tswb ceeb toom, xaiv los tso saib lub tswb hauv zos / tej thaj chaw deb;
• Txhawb tej thaj chaw deb E1 kab sab loopback muaj nuj nqi los pab rau kev ntsuam xyuas ntawm E1 kab;
• Txhawb nqa hauv zos rau qhov chaw taws teeb rov pib dua;
