Features

E1 interface complies with the G.703 recommendation, using fully digital clock recovery and smooth phase-locked loop technology.

Voice port supports FXO and FXS, where the FXO port is connected to the PBX and the FXS port is connected to the user’s telephone.

It supports caller ID display and reverse polarity billing functions.

It supports mutual dialing between different sites.

It’s able to detect when the E1 signal is lost due to power outage or E1 failure on the remote device, and indicate the alarm through indicator lights.

It provide two types of clock: E1 master clock, E1 line clock;

Multiple power supply options are available: AC220V, DC-48V/DC24V, etc.

The DC-48V/DC24V power supply has an automatic polarity detection function, and there is no need to distinguish between positive and negative poles during installation.
