An ATM switch is configured to route ATM traffic from two receive circuits to a destination. One copy of this traffic is discarded in one of the receive circuits so that only a single copy is passed to the ATM switch. Receive circuits contemplate both virtual path (VP) level and card or circuit level metrics for qualification of signals.

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.

A method and system for distributed processing of traffic in a telecommunications node includes receiving a traffic stream at a line card of the telecommunications node. The traffic stream includes a plurality of discrete cells. The cells are forwarded from the line card to a centralized switch of the telecommunications node. The centralized switch identifies cells that are of a particular type. Cells of the particular type are returned from the centralized switch to the line card. The returned cells are processed at the line card.
