    摘要： A system for performing pointer processing on large concatenated payloads, in a processing node of an optical communications networks. The system comprises a plurality of processing strips. Delay blocks are introduced between a pair of processing strips on the pointer interpreter and/or pointer generator sides of the processing strips, so that corresponding data is read on one of the pair of processing strips after a predetermined delay from a time moment when the data is read on the other of the pair of processing strips, in order to overcome timing constraints arising from the need to synchronize the processing of a concatenated payload across multiple strips. Inter-chip communication blocks are introduced in order to allow concatenated payloads to be processed on different chips.

    摘要： A data generator and a method for generating large concatenated SONET/SDH frame are provided. The method comprises initiating a set of programmable register values with frame parameters, generating data slices comprising a plurality of STS-1 blocks based on said frame parameters, and collecting the data slices to generate a frame. Whenever a large concatenation mode within said frame parameters assumes an ON state, the data slice generation includes, setting the pointer value to a predetermined fixed pointer value and generating payload bytes of every STS-1 block having a concatenation indication such that the B3 byte of the STS-1 block assumes a predetermined fixed B3 value. The data generator for generating SONET/SDH type data frames. The data generator comprises a plurality of processing strips for generating a plurality of associated data slices having STS-1 blocks. Each strip may operate in a large concatenation mode in which a fixed pointer value and a fixed B3 value in assumed for each STS-1 block within the data slice. A data collection block of the data generator collects generated data slices into a data frame. Among the advantages presented by the method and system of the preferred embodiments of the invention is the ability to generate arbitrary large concatenated payloads, without communication between processing strips of data generators.
