kawa,
ok, so for your problem, i don’t think hopping is the issue. actually, i would suspect two possibilities :
1/ one trx is faulty, but the wrong TRX was locked –> the faulty trx carries more traffic, therefore, there is more call drops, etc.
2/ the faulty trx is locked, indeed, so the other trx’s are going to carry more traffic. It is a possibility that another trx is also faulty, so by locking one TRX, you actually reveal another faulty trx.
🙂
that sounds more probable than a wrong hopping management, but who knows…
