Umgangatho ogqwesileyo we-Usb Ukuya kwi-Rs485 422 Isiguquli-Isiguquli se-E1-FE esakhiwe ngefreyimu ye-Fremed JHA-CE1fF1-JHA

I-Fremed E1-FE interface Converter JHA-CE1fF1

Isishwankathelo

Lo mguquli we-interface usekelwe kwi-FPGA, ukubonelela nge-framered interface ye-E1 kunye ne-interface enye ye-Ethernet ukufezekisa i-10/100Base-T yokuhanjiswa kwedatha ye-Ethernet kwitshaneli ye-E1. Kukusebenza okuphezulu, ukuzifundela ibhulorho ye-Ethernet. Esi sixhobo sisixhobo sokwandiswa kwe-Ethernet, sisebenzisa inethiwekhi (PDH / SDH / Microwave) ebonelela ngeshaneli ye-E1 ukufezekisa ukudibanisa kwe-Ethernet yendawo kunye ne-remote kunye ne-serial interfaces ngexabiso eliphantsi. Isixhobo sinomsebenzi wokuvavanya i-loop ye-inter-set ukuququzelela ukuqaliswa kweprojekthi kunye nokugcinwa kwemihla ngemihla.
