30Voice + FE over E1 PCM Multiplexer

View : 769
Type : E1 PCM Multiplexer
Description :

The device provides one E1 interface, 30 telephone outputs, and an optional 64K Ethernet interface (or 29 telephone outputs + one 128K Ethernet interface or other combinations).

Overview

The device provides one E1 interface, 30 telephone outputs, and an optional 64K Ethernet interface (or 29 telephone outputs + one 128K Ethernet interface or other combinations). The device is fully digital and has reliable and stable operation, low power consumption, high integration, small size, and easy installation and maintenance.

Features

E1 interface complies with the G.703 recommendation and adopts all-digital clock recovery and smooth phase-locked loop technology.

Voice port supports FXO/FXS/2&4-wire EM/2&4-wire audio/magnetic telephone interfaces. The FXO port is connected to the PBX, and the FXS port is connected to the user’s telephone.

It provides one expansion interface that can expand one asynchronous data such as RS232/RS485/RS422/Manchester code, etc.

Ethernet interface rate is 10/100M, full/half duplex adaptive.

It supports caller ID display, reverse polarity charging, and fax function.

It supports the mutual dialing function of both sides.

It can detect whether the remote device is powered off or the E1 is not connected when the E1 signal is lost.

It supports 3 configurations: 30*telephone + 1 64K Ethernet, 30*telephone + 1 serial port, 29*telephone + 1 128K Ethernet, 29*telephone + 1 64K Ethernet + 1 serial port.

It provides 2 clock types: E1 master clock and E1 line clock;

It provides 3 loopback functions: ANA (local loopback), DIG (Ethernet interface loopback to the remote end), and REM (remote Ethernet interface loopback to the local end).

It has a pseudo-random code testing function (PATT), which is convenient for line commissioning and can be used as a single E1-bit error tester.

Multiple power mode options: AC220V, DC-48V/DC24V and so on.

The telephone interface is equipped with lightning protection, which can withstand short-circuit current wave 10/700μs and open-circuit peak output voltage 6KV, in accordance with the GB/T17626.5 (IEC61000-4-5) standard.
