Statistical multiplexers (1a, 2a) comprise a group (5) of uncompressed transmission channels, and a group (4) of compressed transmission channels. The transmission capacity of the group (5) of uncompressed transmission channels is greater than the transmission capacity of the group (4) of the compressed channels. The statistical multiplexer comprises means for extracting packet part of signals sent from the group (5) of uncompressed transmission channels, and first means for rearranging the extracted packets dynamically in the group (4) of compressed transmission channels. Signals are compressed by reducing the proportion of idle signals in the signals sent to the compression transmission channels (4) by the extraction means and the first rearrangement means.
