Dear list,

I recently integrated nanoBTS under OpenBSC. They work fine, but I encountered 
the following limitations.

1. Dynamic PDCH/TCH switching is allowed to be configured, but not working. The 
timeslots are stuck in TCH/F mode and never converted to PDCH. Is there any 
trick I need to do other than setting the channel type to TCH/F_PDCH?

2. No matter what I do, the BTS only schedules one uplink timeslot. If I 
understand it correctly, the PCU implementation in this case is inside the 
NanoBTS. Is there a way to change for example an NVRAM parameter to allow a 
more balanced UL/DL timeslot ratio?

3. Multi-TRX setup: it is quite a limitation that you cannot use any timeslots 
as PDCH in a multi-TRX setup on the secondary or third carriers at all. I don't 
think there is any solution to that, but it worth noting.

I hope someone can point me in the right direction with dyn PDCH switching and 
the single UL TS issue.

Thanks!

Regards,
Csaba
