Introduction

The E1 voice multiplexers provide an E1 access, 30-way telephone outputs, 1 RS232 / 422/485 or Ethernet optional. Equipment electrical part for the whole digital circuits, machine reliability, stability, low power consumption, high integration, small size, easy installation and maintenance. Many customers are telecommunications operators E1 leased lines used in computer networking, this equipment can be rented at the E1 line opened a few road phone, you can make free calls between headquarters and branch offices of this.

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;

◆ support FXO voice port FXS ports and ports, EM2 / 4 audio interface, FXO port and PBX docking port and the user is connected to FXS telephone;

◆ providing four expansion interface, can be extended from 1 to 4 asynchronous data, such as RS232 / RS485 / RS422 / Manchester codes; 

   or 1 to 8-way switch, 1 to 4-way voice, or two / four-wire audio, etc.;

◆ Ethernet interface 10M / 100M, full / half duplex fully adaptive, support VLAN division;

◆ Each Ethernet ports support Auto-MDIX (cross / straight cable adaptation);

◆ 1-30 road 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 function (PATT), to facilitate the opening line, which can be when one of E1 BERT to use;

◆ multiple power mode options: AC220V, DC-48V / DC24V, etc;
