Claim One:
1. Reception device able to receive packets in a packet switching network comprising at least two stations, said device comprising: means for receiving packets containing samples from said network, said samples coming from data sampled every period, where the period is from a time base synchronised on all the stations of said network, means for regenerating a counting ramp using a phase-locked loop also delivering a reconstituted clock, means for initialising, at every zero-crossing of the counting ramp, an image counter, the rhythm of which is determined by the reconstituted clock, means for generating image cues at every zero-crossing of said counter, and means for reconstituting a synchronization signal from said image cues, means for transmitting the synchronization signal to an item of remote equipment to be synchronised wherein the device comprises: means for receiving a return synchronisation signal identical to the synchronisation signal received by the equipment, means for extracting return image cues from the return synchronisation signal, means for transmitting, to the phase-locked loop, a sum between the received sample and a sample of a counting signal delivered by the image counter.
