dear,
pleas explain to me the reason; the TCH traffic is zero (no any call on the cell or site totally):
1. TCH availability= 100%.
2. no any fault on the TBS.
3. no cell bering.
4. no blocking TRX.
5. in some cells no ICMB, but in some I have.
6. layar 1 for 1800 band and and 2 for 900.
7. there is many subscribers around site.
I can ask my question by another way:
why there is call some time buy in another day
on the same cell there is no any call?
thanks for co-operation
