OEM Maƙerin Rs485 Zuwa Canjin Ethernet - Co-directional 64K-FE Converter JHA-CE1tF1 - JHA

Dubawa

The G.703 (Co-Directional G.703) dubawa raba 64Kbps sake zagayowar zuwa 4 raka'a tazara, shi yana amfani da"0101" wakiltar "0", "1100" wakiltar "1" . Ta hanyar musanya polarity na canji na toshe kusa, siginonin binary suna canza sigina mai mataki uku. A cikin kowane rukuni na 8th an lalata shingen madaidaicin polarity, ta haka don watsa siginar lokacin 8KHz. Ta hanyar coding na sama, G.703 co-directional 64Kbps siginar zai iya cimma nasarar watsa siginar lokaci na 64KHz da 8KHz da 64KHz da siginar bayanai na 64Kbit/s a cikin hanya guda tare da madaidaicin layi guda biyu.
Wannan mai canzawa yana ba da haɗin gwiwar G.703 mai haɗin gwiwa guda ɗaya da kuma haɗin Ethernet guda ɗaya don cimma nasarar watsa bayanan 10/100Base-T Ethernet akan tashar G.703. Babban aiki ne, gadar Ethernet mai koyon kai. Wannan na'urar ita ce na'urar faɗaɗawa ta Ethernet, ta amfani da hanyar sadarwa (PDH/SDH/Microwave) wanda ke samar da tashar G.703 don cimma haɗin haɗin gida da na nesa na Ethernet tare da musaya na serial a farashi mai rahusa. Na'urar tana da aikin gwajin madauki na tsaka-tsaki don sauƙaƙe ƙaddamar da aikin da kiyayewa yau da kullun.
