30 Voice (POTS/FXS/FXO) over E1 Converter | 30*voice MUX

Description

Function

30 voice (anolag phone) over E1 Converter provides conversion between ITU-T G.703 standard E1 and 1-30 voice, realize the long-distance extend of telephone line through E1 channel. BD-E1-MUX30 is a high-performance, multi-type long-range Ethernet bridge. Its small size, low cost and very appropriate to the cost-sensitive bridging applications.

Features

●   realizes long-distance monitoring of local device to the remote device based on self-copyright IC;

●   provides two clock types: E1 master clock, E1 line clock;

●   realize the automatically rate set of local device to remote device

●   has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;

●   E1 supports 75Ω unbalanced and 120Ω balanced impedance at the same time;

●   Provides 30 voice channels, support calling indication

●   Voice port supports O port and S port, O port connects switch and S port connects user’s phone;

●   Support one ethernet port(option),realize 1*ethernet and 30channel phone over E1 multiplexer transmission;
