Change subject: osmo-bts-trx/l1_if.c: use channel combination III for TCH/H ...................................................................... osmo-bts-trx/l1_if.c: use channel combination III for TCH/H Currently the channel combination II is used for TCH/H, which allows only one lchan to be allocated. The reason is that it saves a bit of CPU by disabling UL burst detection on lchan 1. There is also the channel combination III, which allows to increase channel capacity, providing two lchans on a single TCH/H timeslot. Ideally we should implement some dynamic II <-> III switching depending on the network load level. But for now this change replaces the channel combination of TCH/H by III, until dynamic switching is implemented.
