OEM Manufacturer Rs485 Ki Itarangi Converter - Co-Directional 64K Converter JHA-CE1tV1 – JHA

Kaihuri 64K-V.35 TakitahiJHA-CE1tV1

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-V.35 / V.24 atanga converter whakarato ITU-T tahi-64K G.703 paerewa E1 atanga me te paerewa V.35 atanga faafariuraa i waenganui i te paparanga tinana / V.24. Whatunga ki te whakarato i nga whakawhitiwhitinga haumaru i waenga i nga taputapu o nga atanga rereke, te hononga korekore. Ko nga taputapu E1 te waahanga hongere e pa ana ki nga mokamoka taputapu tuku e waatea ana, me te hiahia ki te whakawhiti raraunga ki a V35 / V24 anake te kaweake o te waa, ko te aratau atanga raraunga ko DCE, me te DTE, DCE ranei te taputapu u.
