2019 Ikhwalithi ephezulu Rs232 Kuya ku-Rs485 - I-Co-Directional 64K Converter JHA-CE1tV1 - JHA

I-Co-Directional 64K-V.35 ConverterI-JHA-CE1tV1

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.
I-64k-V.35 / V.24 isiguquli esibonakalayo sihlinzeka nge-ITU-T co-64K G.703 isixhumi esibonakalayo se-E1 esijwayelekile kanye nesixhumi esibonakalayo esivamile sokuguqula i-V.35 phakathi kwesendlalelo esibonakalayo / V.24. Inethiwekhi yokuhlinzeka ngokuxhumana okuvikelekile phakathi kwamadivayisi ezindawo zokusebenzela ezahlukahlukene, ukuxhumana okungenamthungo. Isigaba sesiteshi se-E1 sisebenza ezikhaleni zemishini yokudlulisa ezitholakalayo, kanye nesidingo sokudlulisa idatha kanye nokuthekelisa kuphela kwe-V35 / V24 yalesi senzakalo, imodi yokusebenzelana kwedatha yi-DCE, enedocking ye-DTE noma ye-DCE.
