💫Ø Integrated circuit based on independent intellectual property rights;
꧑Ø It can be detected that when the optical signal is interrupted, it is the fault of the optical fiber line or the remote device, and is indicated by the indicator light;
♍Ø Support both adaptive 120Ω( balanced )and 75Ω( unbalanced )two kinds of impedance, no longer need to make settings;
🌄Ø System through rigorous testing and practical verification, in full compliance with the ITU-T G.703, G.704 and other recommendations;
ℱØ Hardware to achieve the choice of any one of 31 time slots (framing effective);
💯Ø Provides three kinds of loopback functions: optical port local self-loop (ANA), E1 local self-loop (DIG), the command to the client E1 back to the local loopback;
💮Ø Provide pseudo-random code test function (PATT), equivalent to built-in bit error detector, easy to open circuit test;
ꦍØ Optional AC 220V, DC -48V, DC +24 V, DC power supply without positive and negative points;
