We always have the same problem and we also hear some bip,have one way communication and drop calls.
We have reset the BSC-no result-,then switched the IEM-no result- and also resEt the TCU-no result-.
Areal nightmare.
Moreover the other operator and a part of the neighbor island that have another PLMN has the same problem.
Should we reset the MSC???
What do you think about this problem?
