Product Description
  The E1 voice reuse device is to provide two E1 access 1 +1 backup protection 30 phone output the device part of the whole digital circuit the whole work is reliable stable low power consumption high integration small size Easy to install and maintain. Many telecom operators are customers rent E1 line you can use the device in the E1 leased line to open 30 telephone so that the headquarters and the branch can be free between the call.
Functional Properties
◆ based on independent intellectual property rights of integrated circuits;
◆ E1 interface in line with G.703 recommendations the use of all-digital clock recovery and smooth phase-locked technology;
◆ Provide two 1 + 1 backup E1 interface the main backup function the main E1 disconnect spare E1 work to ensure that the business is not interrupted;
◆ Voice port to support FXO / FXS / two four-line EM / two-wire audio / magnet phone interface FXO port and program-controlled switches docking FXS port and the user's telephone connected;
◆ 1-30 voice access support caller ID / reverse polarity billing / fax function;
◆ Telephone interface to support the two sides of the site of the number of features;
◆ Can detect E1 signal is lost when the end of the device shutdown or E1 unreasonable;
◆ Two clock modes are available: E1 master clock E1 line clock;
◆ (EA) Ethernet interface to remote loopback (DIG) and command the remote interface to the local loopback (REM) of the Ethernet interface.
◆ Pseudo random code test function (PATT) easy to open the line that can be used as an E1 error meter to use;
◆ A variety of power supply options: AC220V DC-48V / DC24V etc .; support AC + DC; AC + AC; DC + DC and other dual power backup mode;
