Idumela eliphakeme i-Rs485 Ku-Ethernet - Isixhumi esibonakalayo E1-RS530 Engafakwanga Uhlaka JHA-CE1R530 - JHA

Isiguquli esibonakalayo se-E1-RS530 esingazimeleI-JHA-CE1R530

Uhlolojikelele

Le divayisi ihlinzeka ngesixazululo esinomnotho sokufinyelela kwedijithali kumasevisi enethiwekhi ye-E1 kanye ne-Fractional E1. Ngekhebula le-adaptha, idivayisi ingaxhuma kwenye idivayisi ye-DTE, njengerutha, ngamanani edatha angu-64Kbps kuya ku-2048Kbps. Idatha yomsebenzisi ifakwa kuhlaka lwe-E1, kusetshenziswa inombolo edingekayo kuphela yezindawo zesikhathi, isabelo sesikhathi sifezwa ngokuya nge- isivinini sembobo yedatha nokusetha okwenziwa ngesandla kwamaswishi e-DIP. I-GVE isetshenziswa kabanzi kunethiwekhi yokuxhumana, kokubili ku-WAN kanye nenkundla yokuxhumana ye-LAN.

Izici

• Ngokusekelwe ku-IC ye-self-copyright.
• Ungakwazi ukuhlukanisa lapho kuphelelwa umoya noma ikhefu lapho isignali ephakathi yokudlulisela i-E1 E1 ilahleka
• Ngenkathi isekela i-120Ω / ibhalansi eguquguqukayo kanye ne-75Ω / Imbalance impedance, asikho isidingo sokwenza izilungiselelo
• Uhlelo ngokuhlolwa okuqinile nokuqinisekisa okungokoqobo, okuhambisana ngokugcwele ne-EIA-530, ITU-T G.703, G.704 nezinye izincomo; inikeza imisebenzi emithathu ye-loopback: I-E1 loopback yendawo (ANA), i-RS530 loopback (DIG) yenza kontanga RS530 loopback (REM);
• Umsebenzi wokuhlola ikhodi okungahleliwe, okungukuthi ukwenza lula ukuvulwa komugqa, lapho umuntu engeza ne-2M BERT
• I-DTE noma i-DCE ukusekelwa kanye nokuxhumana; I-RS530 interface isekela ukushintshashintsha okushisayo
• Umsebenzi wewashi le-RS530 usekela iwashi langaphakathi, iwashi langaphandle kanye newashi lomugqa;
• Ukunikezwa kwamandla kwe-AC 220V, DC -48V, DC + 24V, DC awekho amaphuzu amahle noma amabi;
