Abstract: In a communication network for transferring signals, e.g. according to the SONET or SDH standards, interconnecting node devices are provided consisting of parallel processing modules (9-T, 9-R). A plurality of processing modules with first and second interfaces rearrange/insert/extract tributary signals and configurable multiplexing/demultiplexing means enable each processing module to access any portion of an arbitrarily preselected tributary signal. In a SONET/SDH system, signals between SONET/SDH frames are rearranged on incoming (20) and outgoing (26) main lines = Digital Cross-Connect, or tributary signals are transferred between frames and local lines (16-i-T, 16-i-R) = Add/Drop Function. The invention provides configurable multiplexing/demultiplexing means (22-i, 24-i, 28-i, 30-i) which allow the processing modules to have access to any tributary signals in said frames, thus enabling digital cross-connect and add/drop operations without completely demultiplexing or disassembling frames. In a preferred embodiment, the configurable multiplexing/demultiplexing means includes a pipeline arrangement (22-i, 24-i) connected to all processing modules (9-T, 9-R).

Abstract: PCT No. PCT/EP95/01426 Sec. 371 Date Oct. 7, 1997 Sec. 102(e) Date Oct. 7, 1997 PCT Filed Apr. 15, 1995 PCT Pub. No. WO96/33563 PCT Pub. Date Oct. 24, 1996A modular approach to the mapping of data in and from a standard SDH/SONET signal is described. A module has interfaces (T0-T8) which allows to connect to it to other of its kind and thereby achieving higher data rates, i.e. access to standard signals of higher levels. By choosing among different interconnection schemes, arrangements comprising a plurality of modules are also able to support concatenated data traffic.
