Product Details

E1 PCM 4POTS over coaxial cable

 

Product Overview

This device provides one E1 interface,4Channel telephoneoutput,2Channel RS232/422/485and4Channel Ethernetoptional. The device circuit is the digital circuit. The working isreliable, 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 computer networking, can use this device in the E1 leased line opened on a few channel telephone. Then between Headquarters and the branch can callfor free.
