4Voice + FE + 4*RS232/485/422 over E1 PCM Mux

View : 849
Type : E1 PCM Multiplexer
Description :

The device can provide 4 telephone outputs, 1 Ethernet interface with a bandwidth of 2M, and 2 RS232/422/485/dry contact(or 4 RS232/422/485).

Overview

The device can provide 4 telephone outputs, 1 Ethernet interface with a bandwidth of 2M, and 2 RS232/422/485/dry contact (or 4 RS232/422/485). The device uses a fully digital circuit, which has high reliability and stability, low power consumption, high integration, small size, and is easy to install and maintain.

Features

The device can monitor the alarm status of the remote end

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

Voice interface supports FXO and FXS ports, EM2/4 audio interfaces, FXO port is connected to the PBX, and FXS port is connected to the user’s phone.

The device provides 4 expansion interfaces, which can expand 1 Ethernet interface (bandwidth 2M), 1-4 asynchronous data such as RS232/RS485/RS422/Manchester code, etc.

Ethernet interface rate is 10/100M, duplex/half duplex adaptive, and supports VLAN.

It supports caller ID display and reverse polarity billing functions.

It supports mutual dialing function among different sites.

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

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

It provides 3 loopback functions: E1 interface Loopback (ANA), Ethernet interface Loopback (DIG), Remote Ethernet interface Loopback (REM).

The device 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.

E1 can support N * 64k (N = 1-32) rate, which means the rate is adjustable from 64K-2048K.

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

Telephone interface with lightning protection, lightning reached IEC61000-4-5,Short circuit current wave 8/20μs,open-peak output voltage 6KV standards.
