1.Realize long-distance monitoring of local device to the remote device 2.8 channels voice, support caller ID and anti-polarit
GQ4008M  mini 8 channel voice POTS over E1 PCM multiplexer
Introduction

       GQ4008M Voice over E1 PCM Mux can provide 1-8 channels 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.

      

      GQ4008M 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.

      GQ4008M  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.
