摘要： A network switch includes multiple interface cards (350 and 375) and a backplane (300) that interconnects the interface cards (350 and 375). The interface cards (350 and 375) receive network traffic and perform time and line switching on the data. The network traffic can include a combination of time division multiplexed (TDM) data and network data (e.g., ATM cells, IP packets). In one embodiment, the channels that carry network traffic to the interface cards (350 and 375) are pre-configured as either TDM channels or network channels. The channels are processed as appropriate for their respective types by the interface cards. Because both TDM and network traffic can be processed by a single interface card (350 or 375), the number of cards (350 and 375) within the network switch can be reduced.

摘要： An apparatus is described that has a line level selection unit and a path level selection unit. The line level selection unit forms a primary traffic stream and a secondary traffic stream. The primary traffic stream comprises a plurality of signals that are received on one or more working or protection ingress lines. The secondary traffic stream comprises the path level protection signal for each of those signals within the primary traffic stream that have path level protection. The path level selection unit receives the primary traffic stream and the secondary traffic stream and forms an egress traffic stream by replacing, with its corresponding path level protection signal, any of those signals within the primary traffic stream that have path level protection and that have failed.

摘要： An apparatus (Fig. 4, 412) is described that has a line level selection unit (401) and a path level selection unit (402). The line level selection unit (401) forms a primary traffic stream (425) and a second traffic stream (426). The primary traffic stream (425) comprises a plurality of signals that are received on one or more working or protection ingress lines (405). The secondary traffic stream comprises the path level protection signal for each of those signals within the primary traffic stream (425) that have path level protection. The path level selection unit (402) receives primary and secondary traffic stream (425, 426) and form an ingress traffic stream (410) by replacing with its corresponding path level protection signal any of those signals within the primary stream that have path level protection and have failed.
