TD-E1-8*FXO-FXS-MUX offer 8 POTS (FXO/FXS) over E1 transmission also can with 1-4 Ethernet and 1RS232 together

Product Characteristics

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

• provides 1-4 channels Ethernet connectors, 10M/100M, full /half duplex self adapt, support VLAN.  supports AUTQ-MDIX (cross over and straight through self adapt)

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

• provides two clocktpes 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

• El supports 750 unbalanced and 1200 balanced impedance at the same time;

• Provide Ethernet auto reset function, run more stably.

• Various Ethernet data indicate functions, which indicate data transmission status timely;

• Provides 1-8 voice channels, support calling indication

• Voice port supports O port and S port, O port connects switch and S port connects user’s phone; also  support 2&4 wire E&M for your option

• PS232 channel can transfer asynchronous serial data with self-adaptable baud rate of 300 to 115.200;
