you need to trigger the repeated SACCH feature earlier.
try to reduce RADIOLINK_REP_DL_ SACCH to 10 for example, or even lower.
can you check the value of mc992 ? are there a lot of activation, compared to the number of tch calls ?
then what’s the ratio of mc993/(mc993+mc994) ?
finally, can you deactivate RSACCH feature, see if the behaviour is better after that ?
EN_REP_SACCH = 0
