• Ukusekela Inombolo Yocingo umsebenzi ofanayo wesayithi ngayinye;
• Ichweba le-FXO ne-FXS lokusekela izimbobo zezwi, imbobo ye-FXO kanye ne-PBX yokudokha, imbobo ye-FXS ixhunywe kufoni yomsebenzisi;
• Isixhumi esibonakalayo se-E1 sithobela i-G.703 encoma ukusebenzisa ukutholwa kwewashi ledijithali kanye nobuchwepheshe obushelelezi bokukhiywa kwesigaba;
• Ingakwazi ukubona lapho isignali yokubona ilahleka kudivayisi yokugcina enikwe amandla phansi noma i-fiber barrier, futhi nge-LED ibonisa i-alamu;
• Ngalesi siphetho ekuboniseni isimo somsebenzi idivayisi ekude;
• Nikeza isikhombimsebenzisi se-loopback yesilawuli kude, kulula ukukulungisa umugqa;
• Ibanga lokudlulisa elingaphindiwe elifika ku-2 kuya ku-120 km;
• Izinketho zemodi yamandla amaningi: AC220V, DC-48V / DC24V, njll;
• I-DC-48V / DC24V yamandla kagesi enomsebenzi wokuthola i-polarity othomathikhi, uma ifakiwe ngaphandle kokuhlukanisa phakathi kokuhle nokubi;
• Isixhumi esibonakalayo socingo esinokuvikelwa kombani, umbani ufinyelele ku-IEC61000-4-5 Igagasi elifushane lesekethe yamanje engu-8 / 20μs, amazinga we-voltage evulekile-peak 6KV.
