Hi list, while studing burst_ind (I know that burst_ind must be used in a own controlled network) i see that one SDCCH for a specific operator has been shared by more than one MS (different TMSIs), some MS use for SMS other use for calls. Is that an interpratation error (due the fact of using burst_ind in real networks) or that could be possible? i didn't find explanations on sepcs.
TIA

It's called SDCCH/8 or SDCCH/4 since one on-air timeslot (physical channel) is used to generate 8 (or 4, respectively) SDCCH logical channels.
in GSM, everything is TDMA. Take your time to really understand the TDMA hierarchy.
