30 channel voice POTS over E1 pcm multiplexer

30 channel voice POTS over E1 pcm multiplexer
Product Detailed
1.Realize long-distance monitoring of local device to the remote device 2.30 channels voice, support caller ID and anti-polarit
GQ4030 30 channel voice POTS over E1 PCM multiplexer
Introduction

       GQ4030 Voice over E1 PCM Mux can provide 1-30channels voice signal(FXO,FXS) and 1channel 10/100M Fast Ethernet, which realized phone lines and Ethernet signal distance extensions through E1 channel. It is a point-to-point transmission equipment developed based on FPGA Chips.

      

      GQ4030 use TDM (Time Division multiplexing)DBA technology to multiple variety of service signals to E1 channels, to realize multi-service access function, more suitable for users with many types of service , the device offers a variety of service interfaces to support voice,Ethernet,RS232 etc.

      GQ4030 is perfect monitoring and alarm, high integration rate ,low power consumption, steady performance, convenient used. It is extensively used in the dedicated networks for power, finance,transportation and police to implement integrated access of voice and data.
