IV.
Cell is blocked
If we can see from the OMC console that the logic configuration
for the cell has been completed, but the MS still can not connect to
the network, we can then check whether this cell has been blocked.
When a cell is blocked, the BTS will turn off the transmitting
signal of the BTRM, to which the carrier of this cell corresponds,
which will result in the MS network connection failure.
We can use command "DSP BTSBRDSTAT" to query the BTRM
status on the OMC console and find out if the BTRM to which this
cell corresponds is blocked.
If the cell is blocked, the mobile station will not be able to
connect to the network until the user unblock the cell.
