ABSTRACT:
In a network including an exchange having a masterclock and a number of subscriber stations connected to the exchange, the exchange includes a delay line which receives incoming data. Samples are taken from different taps of the delay line and the tap carrying data in phase with the masterclock is identified and used to output data. In a preferred example, the network is an optical network carrying data cells.
