Abstract
In a wireless telecommunications system (FIG. 1), over-the-air operations of a plurality of base stations (11 ) are synchronized via a synchronization signal that is embedded in the normal communications protocol that is used to convey traffic between a control switch (12) and the base stations. In the physical-layer protocol of the ISDN S or T basic-rate interface, the S or M bits are employed to conduct the synchronization signal. The synchronization signal is generated in the control switch and broadcast therein to port circuit packs (310) via a synchronization bit of a dedicated time-slot of a TDM bus (303).
