2、and up to 32 SDCCH channels for a non-BCCH TRX. In Common BCCH (Segment) operation the Dynamic SDCCH channels are only allocated on TRXs in the BCCH frequency band.Benefit for Operators:The SDCCH signalling capacity in BCCH TRX is increased by 50%, and in non-BCCH TRX by 100%. The increases SMS capa

There is no other operator control or setup.Restrictions:At least BS
