Abstract
The synchronization arrangement includes a waveform and synchronization information generator to supply synchronization information for transmission with a data stream over digital switching networks. The synchronization information includes two different patterns, phased displaced with respect to each other. Interfaces connect peripheral devices to the networks and are adapted to detect a validate the synchronization information. The checks made are in respect of detecting both patterns, the amount of phase displacement, and the correct sequence. If the synchronization information is invalid, the detecting interface selects a data stream from another network exclusively for use by the corresponding peripheral device.
