Framed E1-V.35 interface Converter

    This interface converter provides one E1 interface and one V.35 interface to achieve framed E1 interface transferring to V.35 interface. The data channel rate is 2.048Mbps. The device has an inter-set loop test function to facilitate the project launching and daily maintenance.

● Based on self-copyright IC 
● Have indicator  when the device is power-off or E1 line is broken or lose signal;
● The local device can force the remote device rate to follow it(valid when framed ) 
● The hardware realizes any one of 31-time slot any time slot optional (valid when framed)
● Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
● After strict testing and a practical verification system, completely comply with protocol ITU-T V.35, G.703, G.704
● Have three Loop Back Mode: E1 interface Loop Back (ANA)、V.35 interface Loop Back(DIG)、Command the remote V.35 interface Loop Back(REM)
● Have pseudo-random code test function, easily line opened, can be used as a 2M BER Tester
● AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
