6) judgement is started to control the degree of depth and whether is equaled 0, up-downgoing decay interlock if the judgment is Yes, and up pad value, downstream attenuation value respectively increase 1dB; Up-downgoing decay interlock if the judgment is No, up pad value, the downstream attenuation value 1dB that respectively decays;

7) judge whether start to control the degree of depth equals 0, continue if the judgment is Yes to judge that whether power output is less than rated output power, performs step 8 if the judgment is Yes);

8) judge that whether power output becomes greatly, if the judgment is No, performs step 9), perform step 10 if the judgment is Yes);

9) judge whether power output diminishes, up-downgoing decay interlock if the judgment is No, up pad value, the downstream attenuation value 1dB that respectively decays; Perform step 10 if the judgment is Yes);

10) judge whether down link pad value is greater than 0, up-downgoing decay interlock if the judgment is Yes, up pad value, downstream attenuation value respectively increase 1dB, by starting numerical control decay, on original basis, increase 1dB decay if the judgment is No, be up to down link pad value=0dB, up link pad value=5dB.

Compared with prior art, the present invention has the following advantages:

1, can avoid because isolator is defective, damaging repeater in engineering application, can also reduce O&M cost.

When 2, anxious, find and automatically terminate isolation problem, avoided negative effect that communication system is brought, increase customer satisfaction degree.

3, in equipment, increase isolation alarm function, make to design humanized.
