ATTO & MKT,
The timeslot configuration is done per cell. For isntance, timeslot 3 of TRX2 is configured as SDCCH Dynamic, for one cell.
And then some other were not configured with sdcch dynamic… etc.
The feature itself is an OMC-R feature, which allows the cells within the OMCR to be configured with SDCCH Dyn.
The BSC supports it, obviously, but it is not part of the configuration or the activation process.
