Liistada Qiimaha ee Rs485 422 Beddelka - Wada-jihaynta 64K-FE Beddelka JHA-CE1tF1 - JHA

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.
Beddelaha interface wuxuu bixiyaa hal-jiheeyaha G.703 interface iyo hal Ethernet interface si loo gaaro 10/100Base-T Ethernet xogta gudbinta ee kanaalka G.703. Waa buundada Ethernet is-wax-barashada. Qalabkani waa qalabka fidinta ee Ethernet, iyadoo la isticmaalayo shabakad (PDH/SDH/Microwave) oo bixisa kanaalka G.703 si loo gaaro isku xirka Ethernet-ka gudaha iyo kan fog ee is-dhexgalka ee qiimaha jaban. Qalabku wuxuu leeyahay shaqo tijaabo wareeg ah oo isku xidhan si loo fududeeyo bilaabista mashruuca iyo dayactirka maalinlaha ah.
