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 tsa li-unit, e sebelisa "0101" e emela "0", "1100" e emela "1".Ka ho fapanyetsana polarity ea phetoho ea sebaka se haufi, matšoao a binary a fetola matšoao a mararo.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 ka holimo, lets'oao la G.703 la co-directional 64Kbps le ka khona ho fetisetsa 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, le lisebelisoa tse hlokahalang ho fetisa data le liketsahalo tsa RS232/422/485 feela.
