Descriptions : -
Telephone Multiplexer is a kind of point-to-point fiber transmission multiplexer that developed based on special large scale integrated circuits. It is with perfect alarm function, and has an alternative of 8/16/30/60 channels phones and 1~4 98M linear Ethernet ports, 1~4 serial data.
It can realize SNMP management on stand-alone device via built-in SNMP module. The electric parts are all digital with small volume, high reliability, convenient for maintenance.
