Abstract
Cross-connect method far STM-1 signals of a synchronous digital multiplex hierarchy. Data blocks having differing multiplex structure of the synchronous digital multiplex hierarchy are processed in common in a cross-connect equipment. Controlled via a bus by a microprocessor, AU-4 administration units of STM-1 signals are resolved into virtual container groups of approximately the same length such as TUG-31 and TU-31. After the removal of auxiliary signals that are no longer required, an individual switching matrix network clock matching painter and an individual switching matrix network overhead are respectively attached to these virtual container groups for the formation of uniform switching matrix network input signals (D39, D52). After a rearrangement in a switching matrix network, switching matrix network clock matching pointers and overheads are again taken from the switching matrix network output signals and are evaluated. Subsequently, the input signals (D39, D52) are subjected to a corresponding multiplexing method for the formation of new STM-1 signals. This method is employable in cross-connect and drop insert multiplexing equipment.
