Ntụgharị ntụzịaka 64K-RS232/422/485 JHA-CE1tD1/R1/Q1

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.
64k-RS232/422/485 interface Ntụgharị na-enye ITU-T ngalaba-64K G.703 ọkọlọtọ E1 interface na ọkọlọtọ RS232 / 422/485 ntughari interface n'etiti anụ ahụ oyi akwa. Netwọk iji nye nzikọrịta ozi echekwara n'etiti ngwaọrụ nke oghere dị iche iche, njikọ enweghị nkebi. Kwesịrị ekwesị maka akụrụngwa nnyefe E1 ọwa akụkụ oghere dị, yana akụrụngwa achọrọ iji nyefee data yana naanị oge RS232/422/485.
