The invention concerns a network element and an input-output unit (,) 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 (,) contains a signal processing device (,) that has a reception data memory (,), a transmission data memory (,), a control unit (,) and a processor (,). The processor (,) is a digital signal processor which essentially carries out the processing of a STM-N signal.

Network element and input/output device for a synchronous transmission system

A transmission system is indicated for digital signals combined into a multiplex signal, and a network element for such a transmission system. Each network element contains an adapter circuit to balance phase variations in an incoming multiplex signal. The adapter circuit has a buffer memory (,) for payload data bytes, a write address generator (,) which controls the buffer memory (,) in a way so that a number of payload data bytes is stored within one write cycle, and has a read address generator (,) which controls the buffer memory (,) in a way so that the number of payload data bytes stored within the write cycle is greater than the number of payload data bytes read during the read cycle. Each network element has a sort facility (,) which sorts the read payload data bytes, so that a multiplex signal that is transmitted by a network element has the established frame format.
