OEM/ODM Kaiwhakarato Rs232 Ki Fiber Media Converter - Co-Directional 64K-FE Converter JHA-CE1tF1 – JHA

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.
Ko tenei kaitahuri atanga e whakarato ana i tetahi atanga G.703 hono-tahi me tetahi atanga Ethernet hei whakatutuki i te tuku raraunga 10/100Base-T Ethernet i runga i te hongere G.703. He tino mahi, he piriti Ethernet ako whaiaro. Ko tenei taputapu ko te taputapu toronga o Ethernet, ma te whakamahi i te whatunga (PDH/SDH/Microwave) e whakarato ana i te hongere G.703 ki te whakatutuki i te Itarangi rohe me te mamao e hono ana me nga atanga rangatū i te utu iti. Ko te taputapu he mahi whakamatautau i waenga i nga huinga hei whakahaere i te whakarewatanga o te kaupapa me te tiaki i ia ra.
