Co-Directional 64K-FE Converter JHA-CE1tF1

Txheej txheem cej luam

Lub G.703 (Co-Directional G.703) interface faib 64Kbps voj voog mus rau 4 chav nyob ib ntus, nws siv "0101" sawv cev "0", "1100" sawv cev "1".Los ntawm alternating transformation polarity ntawm lub block uas nyob ib sab, binary signals hloov peb theem teeb liab.Hauv txhua pab pawg thib 8 tau rhuav tshem thaiv kev hloov pauv ntawm polarity, yog li xa 8KHz lub sijhawm teeb tsa.Los ntawm cov coding saum toj no, G.703 co-directional 64Kbps teeb liab tuaj yeem ua tiav lub sijhawm xa cov teeb liab ntawm 64KHz thiab 8KHz thiab 64KHz thiab cov ntaub ntawv teeb liab ntawm 64Kbit / s nyob rau tib txoj kev nrog ib khub sib npaug kab.
Qhov no interface converter muab ib co-directional G.703 interface thiab ib qho Ethernet interface kom ua tiav 10/100Base-T Ethernet cov ntaub ntawv xa mus rau G.703 channel.Nws yog kev ua haujlwm siab, kev kawm tus kheej Ethernet choj.Cov cuab yeej no yog cov cuab yeej txuas ntxiv ntawm Ethernet, siv lub network (PDH / SDH / Microwave) uas muab G.703 channel kom ua tiav hauv zos thiab thaj chaw deb Ethernet interconnecting nrog serial interfaces ntawm tus nqi qis.Cov cuab yeej muaj qhov ntsuas qhov ntsuas qhov sib txuam los pab txhawb qhov project launching thiab tu txhua hnub.
