    I would like to ask what is the effect if SDCCH timeslot configured on BCCH TRX and i have in network for instance with 4 TRX they put one SDCCH on BCCH and the second SDCCH on other TRX.

    Always put at least one SDCCH on the BCCH TRX.
    Then the location of other SDCCH TS is of no importance.

    It is the custom to place them in each “odd” TRX (TRX3, 5, 7, 9…) But that’s just a habit. No logical reason behind.
    (please correct if i’m wrong)

    Hi,
    is there any relevance in which ts should be sdcch. Where is better ts0 or ts1. Not talking about sdcch ts in bcch trx.
    Regards,

    Rex,

    I would recommend TS0 in order to make more room for consecutive TCH TS, just to maximmize the size of the PDCH group.

    7 consecutie TS means 7 possible PDCH in the TRX.

    If the TRX is 1 TCH + 1 SDCCH + 6 TCH
    Then the PDCH group contains only 6 PDCH.
