2019 China Nyowani Dhizaini 16e1 Kuenda ku4ethernet Converter - Co-Directional 64K-RS232/422/485 Shandura JHA-CE1tD1/R1/Q1 - JHA

Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1

Overview  

G.703 (Co-Directional G.703) interface inokamura 64Kbps kutenderera kuita 4 unit intervals, inoshandisa "0101" inomiririra "0", "1100" inomiririra "1". Nekuchinjisa shanduko polarity yeiyo padhuze block, mabhanari masaini anoshandura matatu-level masaini. Muboka rega rega rechisere rakaparadza block yealternating polarity, nekudaro kuendesa 8KHz chiratidzo chenguva. Nekodha iri pamusoro, G.703 co-directional 64Kbps siginecha yaigona kufambisa chiratidzo chenguva che64KHz uye 8KHz uye 64KHz uye sigiyori yedata ye64Kbit/s munzira imwe chete ine mutsara wakaenzana.
64k-RS232/422 / 485 interface converter inopa ITU-T co-64K G.703 yakajairwa E1 interface uye yakajairwa RS232 / 422/485 shanduko pakati peiyo yemuviri layer. Network yekupa kutaurirana kwakachengeteka pakati pemidziyo yeakasiyana mainterfaces, iyo isina musono yekubatanidza. Inokodzera michina yekufambisa E1 chiteshi chikamu chinotsvedza chiripo, uye michina inodiwa kuendesa data uye chete RS232 / 422/485 yekubuda zviitiko.
