Data transmission method e.g. for ATM, involves transferring number of carried data streams via common carrying data stream, from first table operated device to second table operated device

摘要

The method involves transferring a number of carried data streams (a, b, c, d) via a common carrying data stream (1), from a first table operated device (A) to a second table operated device (B). A so-called carried data stream is a sequence of mutually associated stream elements. The carrying data stream is organized into frames and each frame includes stream elements belonging to one or more different carried data streams. Frame multiplexing is used to combine stream elements belonging to one or more different data streams into a common frame, where used frame structures include a frame descriptive index which is included by a reference to a position in a frame descriptive table (FDTA, FDTB). A control stream is established between a control device (23, 23'), and the table operated devices. Control information required to establish a new frame structure, to change an existing frame structure, or to remove an existing frame structure, is transferred between the control device, the table operated devices, via the control stream. An Independent claim is included for a table operated device
