Description

we need to make sure we can make efficient use of the second TRX.

This means
  • a second RSL link has to be established
  • the routing of messages has to be to the correct TRX, which should already work right now, since we use lchan->ts->trx
  • the channel allocator needs to make sure we actually assign channels from both TRX's. For testing, TRX1 could be given preference, or implement a round-robin scheme.
  • The E1 configuration needs to be extended to reflect the new TRAU timeslots
  • The apropriate "CONNECT TERRESTRIAL TRAFIC" has to be sent
Optionally
  • find a way to auto-detect if the second TRX is present, and
    only enable it if it is present.

it seems to work for timeslots 1..7, but there are some issues when timeslot 0 of TRX1 is to be used.

if timeslot 0 of TRX1 is configured as SDCCH/8, it seems to work fine.
