Pan, help very much appreciated 🙂
I’m still confused about layer 2… no T200 in BTS..?
LapDm is on air interface, LapD on Abis interface… each of those protocols use their own T200 timers, aren’t they ? And BTS is indeed having a role.
well, i’m actually quite sure of this, because the BTS monitors the Abis/LapD availability based on T200 timer. (quite sure = almost sure, i’m not stubborn and i’m always glad to be proven wrong)
If BTS detects N200 x T200 expiries, then it will restart its communication board.
