摘要：In order to provide a network node with an improved matrix architecturesuitable for switching TDM traffic streams structured in accordance with different opticalnetworking standards, a network node with a new hybrid matrix architecture is provided ,where a sliced matrix for switching traffic signals at a lower granularity is additionallyused as a center stage matrix in a multi-stage matrix architecture for switching of trafficsignals at a higher granularity. The sliced central switch matrix has a number of at least N(N>1) parallel switch modules. Each switch module is arranged for switching in space andtime domain one of a number of N signal slices of an internal signal format. One or moreslicer/deslicer pairs are connected to the central switch matrix for re-formatting receivedtransport signals structured in accordance with a first transmission standard to and frominternal signals sliced into groups of N signal slices having the internal signal format. Inaddition, one or more pairs of input/output stage matrices are provided for switching inspace and time domain multiplex units of received transport signals structured inaccordance with a second transmission standard and mapping the multiplexing units ingroups of M (M>1) into timeslots of the internal signal format having said N signal slices.
