摘要： Two or more cross-connect ICs are interconnected. Each IC directly receives some, but not all, of the system inputs, and outputs to some, but not all, outputs. Each cross-connect IC has a switch matrix that has the same number of inputs as the system, and a lesser number of outputs that matches the number of outputs of the IC. Each cross-connect IC provides fanout of its direct inputs to a link to each other cross-connect IC. Thus, each IC receives inputs either directly, or from a fanout on another IC.

摘要： A grooming switch comprises plural input ports for receiving multi-time-slot input signals and plural output ports for forwarding multi-time-slot output signals. At least five switching stages alternate between time switching and space switching. The first stage is connected to the input ports, and the last stage is connected to the output ports. Each intermediate stage is connected to two other stages. Collectively, these stages perform compact superconcentration of the input signals, copying and distribution of the compact superconcentrated signals, and unicast switching of the distributed signals to form the output signals, resulting in a grooming switch that is rearrangeably non-blocking for arbitrary multicast traffic.
