Abstract
Abstract A method and apparatus for allowing a radio control console to failsoft to a predetermined channel assignment plan, without disrupting emergency calls then in progress, upon the failure of a CAD host computer link that would ordinarily provide control signals to the console. Channels are deassigned unless they are supporting an emergency call, and then reassigned to a default assignment. If the reassignment would cause a duplicate assignment, the duplicate assignment is first deassigned prior to making the new default assignment.
