A downbanded Cellular network (DBC) is provided to supplement an adjacent or coincident standard Cellular network. The control channels used by the DBC and standard Cellular network are synchronized to ensure proper hand-off between the DBC network and the standard network. Synchronization is achieved by monitoring the separation in time between timing pulses transmitted by the DBC network and the standard Cellular network.

[ What is claimed is:] [1.] A system for synchronizing the control channel of a downbanded Cellular network with the control channel of a conventional Cellular network, comprising:at least one downbanded Cellular switching center for processing control channel information at a first timing, and for generating first timing information which resects said first timing;at least one standard Cellular switching center for processing control channel information at a second timing, and for generating second timing information which reflects said second timing; anda monitor for receiving said first timing information and said second timing information, and for comparing said first timing information with said second timing information to produce a comparison result, and for providing an error signal when the comparison result exceeds a prescribed threshold indicating that the at least one downbanded Cellular switching center is unsynchronized with said standard Cellular switching center.
