thank you for your assistance…
I was tried to change the KEEP_CODEC_HO with different values but nothing happen and also for EN_TFO_OPT. Is the TFO_OPT enabled increase the congestions because we use AMR_HR more than FR or EFR?
About the “FORCE TFO vs AMR=Disable” , may be this parameter there is no impact in B11.
In the ALU document for acceptance tests there is parameter “FORCED AMR vs TFO” which should be ENABLE, but I don’t find it in the OMC-R.
The AMR_HR bit rates for all BSCs are 7,4/5,9/5,15 and DTX(UL/DL) for AMR is active.
I’ll check it and give you feedback.
