Nchịkọta

The G.703 (Co-Directional G.703) interface kewara 64Kbps okirikiri n'ime 4 unit etiti oge, ọ na-eji"0101" na-anọchi anya "0", "1100" na-anọchi anya "1" . Site n'ịgbanwe polarity mgbanwe nke ngọngọ dị nso, akara ọnụọgụ abụọ na-atụgharị akara ọkwa atọ. N'ime otu 8th ọ bụla mebiri ngọngọ nke polarity ọzọ, si otú a na-ebufe akara oge 8KHz. Site na nzuzo nke dị n'elu, G.703 co-directional 64Kbps mgbaàmà nwere ike nweta na-ebufe oge mgbaàmà nke 64KHz na 8KHz na 64KHz na data mgbaàmà nke 64Kbit / s n'otu ụzọ na a ụzọ ziri ezi akara.
