Datenübertragungsschnittstelle für ein Koppelnetzwerk sowie dazugehöriges Testverfahren

摘要

The invention relates to a data transfer interface for a switching network and to a test method for said network. According to the invention, a plurality of test channels (syn0 bis syn3, asw0 bis asw9, tstch) are included in a synchronous time-division multiplex frame comprising a plurality of payload channels (payld). In addition, each channel has additional test bits. A secure data transfer interface is thus obtained, which can be used for online monitoring.
