ARRANGEMENT AND METHOD RELATING TO DIGITAL COMMUNICATION SYSTEMS

摘要

The present invention relates to an arrangement and a method respectively for multiplexing/demultiplexing in a digital communication system using time division multiplex. The arrangement (US) comprises a switching arrangement with first switching means (USC) for switching of data and second switching means (TCU-1, TCU-2) for multiplexing and/or demultiplexing of data. One or more second switching means are connected to the first switching means over terminal connection links comprising a logical interface (USC-link) which comprises a number of time slots arranged in rows and columns. The arrangement further comprises means for providing resources on the interface of the first terminal connection link (USC-link) wherein resources for at least two different functionalities are reserved using reservation of resources based on columns in the interface and reservation based on time slots in the interface respectively.
