Lub koob npe nrov Rs485 rau Ethernet - 8E1-1FE interface Converter JHA-CE8F1 - JHA

Txheej txheem cej luam

Qhov no interface converter yog raws li FPGA, siv rov qab kev taw qhia multiplexing thev naus laus zis los ntim rau ntau E1 circuits kom xa cov ntaub ntawv Ethernet ntawm 100BASE-TX. Nws tuaj yeem paub 1-8E1 channel los hloov ntawm Ethernet optical interface. Cov cuab yeej no tuaj yeem xa cov teeb liab transceiver taw tes rau Ethernet optical interface los ua E1 raws kev sib txuas nrog Ethernet optical interface. Sib txawv nrog cov chaw taws teeb network txuas ntxiv, cov cuab yeej no tuaj yeem txhawb nqa 1-8Channel E1 channel teeb tsa, tuaj yeem ntes tus lej E1 thiab xaiv E1 muaj. Nws tso cai rau E1 kab kis tau tus mob ncua sij hawm sib txawv. ncua qhov sib txawv.

• Txhawb txhua txheej ntawm Ethernet Ua Haujlwm Hom
• CRC lub tswb tsis siv neeg lub tswb tuaj yeem teeb tsa kom cais cov kab tsis zoo sib kis thiab txiav tawm ib qho kev taw qhia. Thaum 2M ceg Circuit Court ib qho kev coj ua yuam kev tshaj qhov pib, txiav tawm qhov kev taw qhia rau lwm qhov kev taw qhia tsis cuam tshuam; uas yog hais, ob qho tib si ntawm Ethernetdirection kis tau tus mob yuav asymmetric
• Cia 8Channel E1 kis tau tus mob ncua sij hawm sib txawv 100ms. Thaum cov paj laum tshaj qhov kev tso cai, lub kaw lus tuaj yeem nres ntawm E1 tias lub sijhawm ncua sijhawm loj dhau los xa cov ntaub ntawv
• E1 interface ua raws li ITU-T G.703, G.704 thiab G.823, tsis txhawb kev siv lub sijhawm teeb tsa
• E1 interface module nrog inter-set moos rov qab Circuit Court thiab HDB3 code Circuit Court
• Kev them nyiaj yug E1 channel hot-plug nyob rau hauv lub cuab yeej, thiab tau txais kev pom zoo
• channel thiab yuav tsis cuam tshuam cov ntaub ntawv xa mus
• Txhawb nqa 1-8Channel E1 channel teeb tsa, tuaj yeem ntes tus lej E1 thiab xaiv E1 muaj;
