Base Station Initialization Failure
2.3.1 Fault Description
When the base station is powered on, the system initialization
aborts, which leads to the BTS start-up failure.
If such problem occurs, the RUN indicators on some boards will
flash rapidly.
2.3.2 Troubleshooting
There are many causes to the BTS initialization failure, and they
can be summarized into the following aspects to help us locate them:
I.
Link failure
The precondition of successful BTS initialization is the
successful establishment of ATM link between the BCIM in the BTS
and the XIE board in the BSC, i.e. the BCIM in the BTS should be
able to intercept the link configuration of the XIE board in the BSC
and establish the corresponding IMA/UNI. If the data configuration in
the BSC is incorrect (or relevant physical link is not configured), the
BCIM will not be able to intercept the link configuration and thus lead
to the link establishment failure.
What’s more, the BOOTP process failure and OML
establishment failure will also lead to the BTS initialization failure.
Please refer to “2.4 OML Failure” for details.
