Reply To: alcatel TCH assign fail radio



good to see you have probably troubleshoot any possible HW failure. Now is the time to investigate radio problems.

Are you using frequency hopping ?
Let’s take one cell. How many TRXs ?
Can you give the TCH alloc efficiency rate @ BH and average during the day
and the TCH Traffic Erlang @ BH and average during the day
PER TRX. (the TCH efficiency is a TRX indicator, I forgot the exact name… should be in the family “RTCH Assignment > Execution”)

If only one TRX is impacted, try to reduce the TRX PREF MARK on this TRX, and increase the TRX PREF MARK on another TRX.
If problem still here, try with another TRX and so on.

Waiting for your reply,
