Wide area communication is lost when the "main" or "Zone" controller is out of service due to scheduled maintenance or equipment failure. This invention provides a "default" channel assignment provision. When the zone controller goes down, pre- determined channels at each site are routed to predetermined locations at other sites (and the con- sole), thereby supporting wide-area calls with some minimum trunking capabilities. Each site control- ler steers calls to a given channel based on their Talk Group. The Talk Group channel steering will be setup as part of system configuration when the system is installed.
