ABSTRACT:
A control channel timing monitor for a simulcast radio frequency (RF) digitally trunked mobile radio communications system continually monitors the outbound control channel timing of each of plural simulcasting transmitting sites. The timing of such monitored signals obtained "over the air" is compared relative to one another and/or to a reference. Fault indications identifying specific sites having faulty synchronization are produced when such comparison indicates lack of synchronization within a programmable tolerance. Appropriate corrective action (e.g., bringing down the control channel and transferring its function to a frequency formerly used for working channel functions) is taken.
