Abstract

The invention concerns a network element and an input-output unit (1) for a synchronous transmission system according to the standard for Synchronous Digital Hierarchy or according to the comparable Synchronous Optical Network (SONET) standard. The input-output unit (1) contains a signal processing device (2) that has a reception data memory (5), a transmission data memory (7), a control unit (6) and a processor (3). The processor (3) is a digital signal processor which essentially carries out the processing of a STM-N signal.
