wheketere rarawe Serial Ki E1 Converter - Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1 – JHA Taipitopito:
Kaihuri 64K-RS232/422/485 Takitahi JHA-CE1tD1/R1/Q1
Tirohanga
Ko te atanga G.703 (Co-Directional G.703) e wehewehe ana i te huringa 64Kbps ki nga waahanga e 4, ka whakamahia te "0101" hei tohu "0", "1100" hei tohu "1". Ma te huri i te polarity huringa o te poraka tata, ka huri nga tohu-rua i nga tohu taumata-toru. I ia roopu 8 i pakaru te poraka o te polarity rereke, na reira ki te tuku tohu tohu 8KHz. Ma te tohu o runga ake nei, ka taea e te tohu tohu 64Kbps te mahi tahi a G.703 ki te tuku i te tohu wa o te 64KHz me te 8KHz me te 64KHz me te tohu raraunga o 64Kbit/s i te huarahi kotahi me te raina taurite takirua.
64k-RS232/422 / 485 kaitahuri atanga whakarato ITU-T tahi-64K G.703 atanga E1 paerewa me RS232 / 422/485 atanga faafariuraa paerewa i waenganui i te paparanga tinana. Whatunga ki te whakarato i nga whakawhitiwhitinga haumaru i waenga i nga taputapu o nga atanga rereke, te hononga korekore. E tika ana mo nga taputapu tuku E1 mokamoka wahanga hongere e waatea ana, me nga taputapu e hiahiatia ana hei whakawhiti raraunga me te RS232 / 422/485 anake nga waahi putanga.
