Isiguquli soMgangatho oPhezulu oPhezulu we-Rs232 - Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1 – JHA

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

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-RS232/422 / 485 i-interface converter ibonelela nge-ITU-T co-64K G.703 ujongano oluqhelekileyo lwe-E1 kunye nomgangatho wokuguqulwa kwe-RS232 / 422/485 phakathi komgangatho womzimba. Inethiwekhi ukubonelela ngonxibelelwano olukhuselekileyo phakathi kwezixhobo zojongano ezahlukeneyo, unxibelelwano olungenamthungo. Ifanelekile kwisixhobo sothumelo lwe-E1 indawo yokubeka itshaneli ekhoyo, kunye nezixhobo ezifunekayo ukudlulisa idatha kunye nezihlandlo zokuphuma kuphela ze-RS232 / 422/485.
