<p>Procedure for transmitting communication information over a transmission link, in variable-length data blocks, by asynchronous type time-division multiplexing. Data blocks (BD0, BD1, ...) are transmitted over the transmission link consecutively and each data block is either useful when it actually contains communication information, or empty, when it contains none. Each useful data block comprises a header sub-block (sbet), of a first type, containing control data and at least one useful information data sub-block (sbd1), of a second type, containing communication information, and each empty data block comprises an empty sub-block (sbv1) of a third type. The sub-blocks of one of the three types of sub-blocks have a length which differs from the respective lengths of the sub-blocks of the other two types. <IMAGE></p> |
