Depending the kind of traffic, different tests can be performed:
• RadioPRBS TEST: an internal PRBS generator can be used to transmit and detect a signal into the
radio link aggregate frame

wards the other...if the MEPs (Maintenance end point) are situated one in loc unit and the other in
the remote one, the ethernet transmission (ports, setting and radio link) can be tested
• LOOP Test: local Base Band and RF Loop to verify the equipment working
11.9.1 Radio BER TEST to check Hardware Failure
• Set Local Radio Timeout=0
• Enable RF Loop or Baseband Loop in Local Radio
• Enable Local Radio BER TEST(step a,b,c)
