ABSTRACT:
A system and method implements a backup digital control channel (DCCH) within a base station in a telecommunications network without relying on backup auto-tuners. When a DCCH fails, a backup DCCH is created by reconfiguring an available time slot in a different transmitter in the associated base station. All neighboring cells and neighboring outer cells are notified of the creation of the backup DCCH in the cell serviced by the base station, and update themselves accordingly.
