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.
Sesebelisoa sena sa ho fetola sebopeho se fana ka sebopeho se le seng sa G.703 le sebopeho se le seng sa Ethernet ho finyella phetiso ea data ea 10/100Base-T Ethernet ho mocha oa G.703. Ke ts'ebetso e phahameng, borokho ba ho ithuta ba Ethernet. Sesebelisoa sena ke sesebelisoa sa katoloso sa Ethernet, se sebelisang marang-rang (PDH/SDH/Microwave) se fanang ka mocha oa G.703 ho finyella Ethernet ea sebaka le e hōle e hokahanyang le li-interface tsa serial ka theko e tlaase. Sesebelisoa se na le ts'ebetso ea tlhahlobo ea li-loop tsa inter-set ho thusa ho qala projeke le tlhokomelo ea letsatsi le letsatsi.
