Awọn ẹya ara ẹrọ
* Da lori ara-copyright IC
* Oluwari opitika ti o ni agbara jakejado
* Nlo tẹlifoonu waya boṣewa 2 (awọn imudani ti kii ṣe tẹlifoonu) ti a ṣeto bi oju opo wẹẹbu aṣẹ-ẹrọ (iyan)
* E1 ni wiwo ni ibamu pẹlu G.703, gba imularada aago oni-nọmba ati imọ-ẹrọ titii pata dan
* Nigbati ifihan opiti ba sọnu, o le rii ẹrọ jijin ti wa ni pipa tabi ti ge asopọ okun, ati tọkasi itaniji nipasẹ LED
* Ẹrọ agbegbe le wo ipo iṣẹ ẹrọ latọna jijin
* Pese pipaṣẹ ni wiwo latọna jijin Loop Back, itọju laini irọrun
* Ijinna gbigbe jẹ to 2-120Km laisi idilọwọ
* AC 220V, DC-48V, DC + 24V le jẹ iyan
* DC-48V/DC + 24V ipese agbara pẹlu iṣẹ wiwa polarity laifọwọyi, nigba ti fi sori ẹrọ laisi iyatọ laarin rere ati odi
