Abstract

The present invention relates to a method of 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 organised 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, wherein 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 (a, a′) is established between a control device (23, 23′), the first table operated device (A) and the second table operated device (B). 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 (23, 23′), the first table operated device (A), and the second table operated device (B), via the control stream (a, a′).

Dependent claims

A method of transferring a number of carried data streams from a first table operated device to a second table operated device via a common carrying data stream, wherein a so-called carried data stream is a sequence of mutually related stream elements, wherein said carrying data stream is organised into frames, and wherein each frame includes stream elements that belong to one or more different carried data streams, characterised in that frame multiplexing is used to combine stream elements belonging to one or more different data streams into a common frame;

in that used frame structures include a frame descriptive index;
in that said index includes a reference to a position in a frame descriptive table stored locally in both said first table operated device and said second table operated device;
in that a so-called control stream is setup between a so-called control unit and said first and said second table operated devices;
and in that control information required to establish a new frame structure, to change an existing frame structure, or to remove a present frame structure, is transferred between said controlled unit and said first and said second table operated devices via said control stream.

1 more element

A table operated device, characterised in that said device includes a frame descriptive table that discloses how different frame structures are constructed and whereby a transformation between carried data streams and a carrying data stream is possible;

in that said table can be changed or updated in accordance with instructions from a control device;
and in that said table operated device is adapted to function in a group of two or more table operated devices where a common table is used within said group to enable a common definition of frame structures employed in the group to be used.
