China Cheap theko Protocol Converter - Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1 – JHA

Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1

Kakaretso  

Khokahano ea G.703 (Co-Directional G.703) e arola potoloho ea 64Kbps ka linako tse 4, e sebelisa "0101" e emela "0", "1100" e emela "1". Ka ho fapanyetsana polarity ea phetoho ea block e haufi, matšoao a binary a fetola matšoao a mekhahlelo e meraro. Sehlopheng se seng le se seng sa bo8 se sentse boloko ba polarity e fapanyetsanang, kahoo ho fetisa lets'oao la nako la 8KHz. Ka likhoutu tse kaholimo, lets'oao la G.703 la 64Kbps le ka fihlella ho fetisa lets'oao la nako la 64KHz le 8KHz le 64KHz le lets'oao la data la 64Kbit/s ka nqa e ts'oanang ka mohala o leka-lekaneng.
64k-RS232/422 / 485 interface converter e fana ka ITU-T co-64K G.703 segokanyimmediamentsi sa sebolokigolo E1 le maemo RS232 / 422/485 segokanyimmediamentsi sa sebolokigolo pakeng tsa lera 'meleng. Marang-rang ho fana ka likhokahano tse sireletsehileng lipakeng tsa lisebelisoa tsa li-interfaces tse fapaneng, khokahano e se nang moeli. E loketse lisebelisoa tsa phetisetso ea li-slots tsa E1 tse fumanehang, le lisebelisoa tse hlokahalang ho fetisa data le liketsahalo tsa RS232/422/485 feela.
