30FXO/FXS PCM Voice Multiplexer Over Optical Fiber

This model 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 30 channels phones and 1~4 98M linear Ethernet ports (optional), 1~4 serial data (optional).The four ports provides witching interfaces, support VLAN，10M/100M self-adapting completely.    It can realize SNMP management on stand-alone device via built-in SNMP module (optional). The electric parts are all digital with small volume, high reliability, convenient for maintenance.
Description
This model is the point-to-point optical transport equipment based on self copyright IC. It is single board structure and provided with complete alarming function. It offers 1~30 voice (FXS/FXO) channels. It can realize SNMP management on stand-alone device via built-in SNMP module. The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.
