2019 Zoo siab Rs232 rau Rs485 - Co-Directional 64K Converter JHA-CE1tV1 - JHA

Co-Directional 64K-V.35 ConverterJHA-CE1tV1

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.
64k-V.35 / V.24 interface converter muab ITU-T co-64K G.703 tus qauv E1 interface thiab tus qauv V.35 hloov dua siab tshiab interface ntawm lub cev txheej / V.24. Network muab kev sib txuas lus ruaj ntseg ntawm cov khoom siv sib txawv interfaces, kev sib txuas seamless. Cov khoom siv E1 channel siv rau cov khoom siv kis tau tus mob muaj, thiab qhov yuav tsum tau hloov cov ntaub ntawv mus rau thiab tsuas yog V35 / V24 export ntawm lub ntees, cov ntaub ntawv interface hom yog DCE, nrog DTE lossis DCE ntaus ntawv docking.
