Method for sending modulated-signal blocks, sending station and data source for the implementation of the method
First Claim
1. A method for sending modulated-signal blocks on multiplexed physical channels, the method comprising:
- forming the modulated-signal blocks by a sending station from respective data blocks of variable size received from a data source on a time-division multiplexing synchronous link, and sending the modulated-signal blocks with a specified block rate on each physical channel, wherein the synchronous link between the data source and the sending station supports dedicated channels respectively associated with the said physical channels, each offering a specified transmission capacity over a sending period inverse to the block rate, and supplementary channels;
transmitting a part at least of each data block from which is formed a modulated-signal block sent on a physical channel from the data source to the sending station on the dedicated channel associated with the said physical channel; and
transmitting another part of the said data block, when the size of the said data block exceeds the said transmission capacity, on at least one supplementary channel of the synchronous link, allocated dynamically to the said physical channel, wherein, on each supplementary channel of the synchronous link allocated to a physical channel for a sending period, an address identifying the said physical channel is transmitted.

Abstract
The modulated-signal blocks are formed by a sending station from respective data blocks of variable size received from a data source on a time-division multiplexing synchronous link. They are then sent with a specified block rate on multiplexed physical channels. The synchronous link between the data source and the sending station supports dedicated channels respectively associated with the physical channels, each offering a specified transmission capacity determined over a sending period inverse to the block rate, and supplementary channels. A part at least of each data block intended for a physical channel is transmitted on the associated dedicated channel. When the size of the block exceeds the transmission capacity, another part is transmitted on at least one supplementary channel of the synchronous link, allocated dynamically to the physical channel.
