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 n'akụkụ, 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.
Nke a interface Ntụgharị na-enye otu ngalaba-directional G.703 interface na otu Ethernet interface iji nweta 10/100Base-T Ethernet data nnyefe na G.703 ọwa. Ọ bụ akwa arụmọrụ dị elu, akwa Ethernet nke mmụta onwe ya. Ngwaọrụ a bụ ngwaọrụ ndọtị nke Ethernet, na-eji netwọk (PDH/SDH/Microwave) nke na-enye ọwa G.703 iji nweta njikọ Ethernet mpaghara na nke dịpụrụ adịpụ na oghere serial na ọnụ ala. Ngwaọrụ ahụ nwere ọrụ nnwale nke etinyere n'etiti iji kwado mmalite ọrụ na mmezi kwa ụbọchị.
