We have several PRI using NFAS. T1 has the PRI on channel 24, T2 has the backup D on channel 24. The other day we lost T1 and the primary D. Shouldn't the backup D have taken over without any interuption in service? In otherwords just 23 B would have dropped calls since T1 took the hit. T2 should have continued going without incident.
Am I correct on this? Or is there a setting I need make in the signaling group or elswhere to make this seemless.
