Co-Directional 64K-V.35 ConverterJHA-CE1tV1

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-V.35 / V.24 segokanyimmediamentsi sa sebolokigolo e fana ka ITU-T co-64K G.703 segokanyimmediamentsi sa sebolokigolo E1 le maemo a V.35 ho fetola segokanyimmediamentsi sa sebolokigolo pakeng tsa lera 'meleng / V.24. Marang-rang ho fana ka likhokahano tse sireletsehileng lipakeng tsa lisebelisoa tsa li-interfaces tse fapaneng, khokahano e se nang moeli. Equipment E1 channel karolo e sebetsa ho lisebelisoa tsa phetisetso tse fumanehang, le tlhoko ea ho fetisetsa data ho V35 / V24 feela ea ketsahalo, mokhoa oa data interface ke DCE, o nang le DTE kapa DCE docking device.
