UGuqulelo oluLungileyo lweNdibaniselwano yoMgangatho-I-Co-Directional 64K Converter JHA-CE1tV1 – JHA

Co-Directional 64K-V.35 ConverterJHA-CE1tV1

Isishwankathelo

I-G.703 (Co-Directional G.703) i-interface yahlula umjikelezo we-64Kbps kwiiyunithi ezi-4, isebenzisa "0101" imele "0", "1100" imele "1". Ngokutshintshisa i-polarity yenguqu yebhloko ekufutshane, imiqondiso yokubini iguqula imiqondiso yemigangatho emithathu. Kwiqela ngalinye lesi-8 litshabalalise ibhloko ye-polarity etshintshanayo, ngaloo ndlela ukuhambisa uphawu lwexesha lwe-8KHz. Ngekhowudi engentla, i-G.703 i-co-directional ye-64Kbps isignali inokufezekisa ukuhambisa uphawu lwexesha le-64KHz kunye ne-8KHz kunye ne-64KHz kunye nedatha yedatha ye-64Kbit / s kwicala elifanayo kunye nomgca we-balanced.
I-64k-V.35 / V.24 i-interface converter ibonelela nge-ITU-T co-64K G.703 ujongano oluqhelekileyo lwe-E1 kunye ne-V.35 yokuguqula ujongano phakathi komgangatho womzimba / V.24. Inethiwekhi ukubonelela ngonxibelelwano olukhuselekileyo phakathi kwezixhobo zojongano ezahlukeneyo, unxibelelwano olungenamthungo. Isixhobo icandelo letshaneli ye-E1 lisebenza kwiindawo zokubeka izixhobo zothumelo ezikhoyo, kunye nesidingo sokudlulisa idatha kunye ne-V35 / V24 kuphela yokuthumela ngaphandle kweso sihlandlo, imowudi yojongano lwedatha yi-DCE, kunye ne-DTE okanye i-DCE yokufaka isixhobo.
