100% Original E1 Interface Converter - Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1 – JHA

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

Uhlolojikelele  

Isixhumi esibonakalayo se-G.703 (Co-Directional G.703) sihlukanisa umjikelezo ongu-64Kbps ube yizikhawu zamayunithi angu-4, sisebenzisa okuthi “0101” simele u-“0”, “1100” simele “1″. Ngokushintshanisa i-polarity yebhulokhi eseduze, amasignali kanambambili aguqula amasignali anamazinga amathathu. Kulelo nalelo qembu lesi-8 libhubhise ibhulokhi ye-polarity eshintshanayo, ngaleyo ndlela ukudlulisa isignali yesikhathi engu-8KHz. Ngombhalo wekhodi ongenhla, isignali ye-G.703 ye-co-directional 64Kbps ingafinyelela ukudlulisa isignali yesikhathi engu-64KHz no-8KHz kanye no-64KHz kanye nesignali yedatha engu-64Kbit/s ohlangothini olufanayo nolayini olinganiselayo.
64k-RS232/422 / 485 isikhombimsebenzisi esibonakalayo sihlinzeka nge-ITU-T co-64K G.703 isixhumi esibonakalayo se-E1 esijwayelekile kanye nesixhumi esibonakalayo sokuguqulwa se-RS232 / 422/485 phakathi kwesendlalelo esibonakalayo. Inethiwekhi yokuhlinzeka ngokuxhumana okuvikelekile phakathi kwamadivayisi ezindawo zokusebenzela ezahlukahlukene, ukuxhumana okungenamthungo. Ifanele imishini yokudlulisela izikhala zezingxenye zesiteshi E1 ezitholakalayo, kanye nezinto zokusebenza ezidingekayo ukuze kudluliswe idatha kanye nezikhathi zokuphuma ezingu-RS232/422/485 kuphela.
