The primitives received from the DSP in the sysmoBTS products are not
any different on the PCU side than on the BTS side. It's a
DATA-indication (GsmL1_PhDataInd_t), and that in turn contains a
GsmL1_MeasParam_t member, which has
* burst Timing
* link quality
for more infoformation.

I'm not quite sure how the transmit path should ever relate to signal
