Airbridge BTS3612A CDMA Base Station
Note:
Performance class A: BTS can withstand the test without any damage and it can run normally in the
specified range. There is not any change in the software or data (all data in the storage or the data being
processed) related to the tested switching equipment. Equipment performance is not lowered.
Performance class B: BTS can withstand the test without any damage. There is no change in the
software or the data in storage. Communication performance is lowered a little, but in the tolerance (as
defined for different products). The existing communication link is not interrupted. After the test, the
equipment can recover to the normal status before the test automatically without any interference of the
operator.
Performance class C: Some functions of BTS are lost temporarily during the test, but they will recover to
normal performance in a specific period after the test (normally the shortest time needed for system
reboot). There is no physical damage or system software deterioration.
Performance class R: After the test, there is no physical damage or fault (including software corruption)
with BTS. Protection equipment damage caused by external interference signal is acceptable. When the
protection equipment is replaced and the running parameters are re-configured, the equipment can
operate normally.
