ABSTRACT:
A TDM switch is configured to route TDM traffic from two receive circuits to a destination. One copy of the traffic is discarded, and a memory selectively stores the other copy for routing to the TDM switch. Receive circuits contemplate both virtual tributary (VT) level and card or circuit level metrics for qualification of signals.
