This device provides one optical interface and one V.35 interface to achieve interface conversion, rate conversion, and timeslot extraction from fiber to V.35 interface. When framed mode, the users can extract timeslot n*64K (n ≤ 31) data channel; When unframed mode, the data channel rate is 2.048Mbps. The device has an inter-set loop test function to facilitate the project launching and daily maintenance.

Description :
This device provides one optical interface and one V.35 interface to achieve interface conversion, rate conversion and timeslot extraction from fiber to V.35 interface.
Overview
Features
● Based on self-copyright IC
● Can detect the reason for optical signal loss is that the device power-off or transmission fiber broken
● The local device can force the remote device rate to follow it(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)、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
● 35 interface supports hot-plug, supports DTE or DCE device interconnection
● Provide 3 clock types: Internal clock, External clock, E1 line clock;
● AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
