8 channel telephone multiplexer over E1 cable
Overview
E1-8Voice+4RS232 Multiplexerprovides oneE1 interface,8 Channel telephoneoutput, 4
ChannelRS232/422/485 and 4Channel Ethernet optional. The device
circuit is the digital circuit. The working is reliable, stable,
and low power consumption, high integration, small size, ease of
installation and maintenance.Many customers are leased from telecom
operators E1 line used in computernetworking, can use this device
in the E1 leased line opened on a few channel telephone. Then
between Headquarters and the branchcan call for free.
Wide industry application . to expand special function according to
different industries
