30 Voice POTS(FXO\FXS) over E1\G.703 multiplexer

bargain

Function

30 Voice POTS (FXO/ FXS) over E1/ G. 703 multiplexer (also called voice to E1 converter) realize 30vice (FXS/ FXO) and ethernet over G. 703 standard E1 transmission, realizing the long-distance extend of telephone line through E1 network. 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 75| ¸ unbalanced and 120| ¸ balanced impedance at the same time;
Provides 30 voice channels, support calling indication
Provide one port ethernet (optional)
Voice port supports O port and S port, O port connects switch and S port connects user phone;
