Voice Over E1

E1-16PCM Multiplexer

This equipment is to provide an E1 access 16 channel voice outputs 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.
◆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 2/4 wire audio interface Magnet phoneFXO 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 function (PATT) to facilitate the opening line which can be when one of E1 BERT to use;
◆E1 can support N * 64k (N = 1-32) rate that rate is adjustable from 64K-2048K;
◆Telephone interface with lightning protection lightning reached IEC61000-4-5Short circuit current wave 8 / 20μs open-peak output voltage 6KV standards;
◆multiple power mode options: AC220V DC-48V / DC24V etc.
