Hi everybody
I just would like to be sure that the paging is only sent on TS0 with OpenBSC, that is to say PCH (which is on CCCH) is only sent on TS0. I read that it could be sent on more time slots (TS2, TS4 and TS6 also) in the GSM specifications. Is it the case in the soft or you just keep the normal multiplexage setting (TS0 only for CCCH+BCCH, 1 slot for dedicated channels and 6 slots for the traffic channels)?
Thanks

Hi,
I think it is the case. The reference would be the SYSTEM INFORMATION TYPE 3 of GSM 04.08, specially the Control Channel Description Information Element and the handling of NM_OC_CHANNEL. Both are done in bsc_hack.c.
I might be totally wrong z.

we only run one timeslot (TS0) for the CCCH (and thus the PCH). Using more timeslots is only required in really large BTS with many TRX - not a case we particularly care about right now.
