1 Function
     BD-E1-MUX16 provides conversion between ITU-T G.703 standard E1 framed interface and4ethernet+1~16channels voice  interface, can through E1 channel provide 1-16 voice, realize the long-distance extend of telephone line through E1 channel. It also provides one RS232 data channel.

      The voice and data multiplexer can automatically connected to the LAN with its uninterrupted learning the MAC address and the address as another purpose of the frame relay LAN. The 16voice and ethernet to E1 interface converters widely used for LAN and Wan networking, control, and so on, and particularly applicable to the network users to the network users with a single E1 channel access data and voice at the same time.

2 Features

 realizes long-distance monitoring of local device to the remote device ;

 provides 1~16 channels Ethernet ports,10M/100M,full half duplex self adapt, support VLAN；

The Ethernet interface supports AUTO-MDIX( cross over and straight through self adapt)；

4Ethernet interfaces support channel separate function, can set VLAN based on TAG

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

provides 3 kinds of loop-return function, namely E1 self-looping at local end, Ethernet self-looping at local end, ordered to self-loop at remote end;

 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;
