i see no problem with that reject. i think it makes sense to reject TSC,
if it does not match the TSC of first TRX. since trx manager interface
seems to be designed to handle each TRX individually (even might be
possible to run on different transceivers for one BTS), i would think it
is a good idea to set TSC for every TRX.
