the signalling between bts & bsc is on LAPD. I would say that for every TRX(voice channels) u also need to reserve a channel for signalling.
type of lapd – concentration, multiplexing.

e.g of lapd concentration on a PCM ts0 – sync, ts-1 will e for trxc signalling and subsequent 2 ts for traffic channels 1-8
