Features

Based on proprietary integrated circuits;

alarm status can be monitored on the end;

E1 interface complies with G.703, all-digital clock recovery, and smooth phase-locked technology;

Voice port supports FXO and FXS port, EM2/4 wire interface, Magnet phone, FXO port docking with program-controlled switchboard, FXS port connected to the user’s telephone

1-16*voice access, support caller ID function and reverse polarity billing functions;

Support Telephone Number mutual function of each site;

E1 signal can be detected as a barrier to the end device is lost or shut E1;

provide two kinds of clock ways: E1 master clock, E1 line clock;

provides three kinds of loopback: E1 local loopback (ANA), the Ethernet interface to the remote loopback (DIG), command peer Ethernet interface to the local loop (REM);

There are pseudo-random code test functions (PATT), to facilitate the opening line, which can be when one of E1 BERT to use;
