Hi Zbuigniew
TCH 3101 expiry will not be noted by user if it is less than MAXRET.After that,no RACH retry will take place & user have to redial(here is the problem).
The MS resends RACH each time T3101 expires till it reaches MAXRET(BTS parameter).
Regarding call drop,it is totally a vendor dependent issue.Some incorporate it in call drop,some doesn’t.
