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

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.

● 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.
