When the BTS is powered on, the system initialization fails, which leads to BTS startup
failure.
In this case, the RUN indicators of some board flash fast.

Remarks
BTS
configuration
data error
1. Check the data configuration of
MBPM.
2. Check the data configuration of
MTRB.
Reconfigure correct data.
Clock Failure
Check the following items:
1. Whether the BTS clock signal is
correct.
2. Whether the clock output of BBPM is
normal.
3. Whether the connection between
MBPM and GPS antenna is normal.
4. Whether more than 4 satellites are
locked.
The fault may be caused by
geographical factors. If less than 4
GPS satellites are captured, the
BTS may be unable to obtain
reliable clock signals.
Query the special status of MBPB
so as to query the clock signals of
the BTS. Execute the command
DSP
BTSBRDSPECSTAT:BRDTP=MB
PB, and then view the Clock state
part in the returned result.
After OML is successfully
established, BSC sends the
corresponding configuration
data. In this case, some BTS
boards cannot start normally
unless correct clock signal is
available.
BSC
configuration
data error
(The
corresponding
physical link is
unavailable)
Check the link configuration of BSC.
Configure correct data.
To successfully initialize the
BTS, an ATM link should have
been successfully established
between BTS MBPM and BSC
CXIE, MBPM should have
detected the link configuration
on CXIE of the BSC, and the
UNI link to the ATM link should
have been established.
OML Failure
