Abstract
A system for providing a backup network is disclosed that includes a glare detection circuit, an arbitration circuit, and a line control circuit. The glare detection circuit receives a dial signal associated with the call control circuit and a cause value from a backup circuit, and asserts a glare present signal responsive to the dial signal and the cause value being asserted. The arbitration circuit receives the glare present signal and produces an arbitration signal responsive to an arbitration procedure. The line control circuit receives the arbitration signal and determines whether the call control circuit will discontinue an outgoing call on the backup circuit and wait a specified period of time for an incoming call on the backup circuit or wait for the outgoing call on the backup circuit to be answered. Methods and other systems are also provided.
