2019 Tayo sare leh Rs232 ilaa Rs485 - Isku-Tilmaamaya 64K Beddelka JHA-CE1tV1 - JHA

Isku-dubarid 64K-V.35 BeddelkaJHA-CE1tV1

Dulmar

Interface-ka G.703 (Co-Directional G.703) wuxuu u qaybiyaa wareegga 64Kbps ee 4 unug, wuxuu isticmaalaa"0101" wuxuu u taagan yahay "0", "1100" waxay u taagan tahay "1" . Iyada oo beddeleysa polarity isbeddelka ee block ku xiga, calaamadaha binary waxay beddelaan calaamadaha saddex-heer ah. Koox kasta oo 8-aad ah waxay burburisay block of polarity beddelka ah, si ay u gudbiyaan signalka waqtiga 8KHz. Codaynta kor ku xusan, G.703 wada-jihada 64Kbps waxay gaari kartaa gudbinta signalka waqtiga ee 64KHz iyo 8KHz iyo 64KHz iyo calaamada xogta 64Kbit/s isla jihada oo leh xariiq dheeli tiran.
64k-V.35 / V.24 Converter interface bixisaa ITU-T co-64K G.703 interface E1 caadiga ah iyo heerka V.35 interface beddelka dhexeeya lakabka jirka / V.24. Shabakadda si ay u bixiso isgaarsiin aamin ah oo ka dhexeeya aaladaha is-dhexgalyada kala duwan, isku xirka aan fiicneyn. Qalabka E1 kanaalka qaybta waxay quseysaa boosaska qalabka gudbinta ee la heli karo, iyo baahida loo qabo in lagu wareejiyo xogta iyo kaliya V35 / V24 dhoofinta munaasabadda, qaabka interface interface waa DCE, oo leh qalabka DTE ama DCE.
