As we have just seen in #4008 and #4009, there are subtle details that need to be handled correctly when performing RSL CHAN ACT in the following different cases:

• Immediate Assignment
  • nothing really special here
• Assignment (on same cell, different channel)
  • ensure that TA must be specified here (TA of old lchan)
• Async / Sync Handover
  • Make sure we don't specify MS Power / TA to ensure SACCH is only transmitted after the Access Burst was received

We should have good test coverage for OsmoBSC in this area.
