I-OEM/ODM Factory Rs232 Rs485 Converter-Co-Directional 64K-FE Converter JHA-CE1tF1 – JHA

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.
Lo mguquli we-interface ubonelela nge-co-directional ye-G.703 ujongano kunye nojongano olunye lwe-Ethernet ukufezekisa i-10/100Base-T Ethernet data transmission kwi-G.703 channel. Kukusebenza okuphezulu, ukuzifundela ibhulorho ye-Ethernet. Esi sixhobo sisixhobo sokwandiswa kwe-Ethernet, usebenzisa inethiwekhi (PDH / SDH / Microwave) ebonelela nge-G.703 ishaneli ukufezekisa i-Ethernet yendawo kunye ne-remote interconnecting kunye ne-serial interfaces ngexabiso eliphantsi. Isixhobo sinomsebenzi wokuvavanya i-loop ye-inter-set ukuququzelela ukuqaliswa kweprojekthi kunye nokugcinwa kwemihla ngemihla.
