siap bang, makasih pencerahannya.
Artinya tidak bisa menempati traffic channels untuk melakukan panggilan/SMS,bisa jadi kapasitas system sudah full dan ini menyangkut RF/optim.
Reasons for TCH Blocking:
Some of them are-
High Utilization of TCH
Time slot faulty.
Lock TRXs.
HW Problem.
Solutions for removal of TCH Blocking:
Implement half rate or Dual rate.
Check FRL & FRU.
Add another TRX. If TRX addition not possible, try to share the traffic of that cell with the neighboring cell by changing tilt or orientation.

bang, newbie mau tanya soal alarm TCH block di bts 2G Huawei itu apa ya artinya? dan cara clearing alarm nya gmana ya? thx
kalau ds3 apa kepanjangannya??????
Exceptional post but I was wanting to know if you could write a
litte more on this subject? I’d be very grateful if you could elaborate a little bit more. Many thanks!
Thanks ya…
good
