Abstract
A digital bit stream from a first synchronous link is timed by a first clock and is to be sent over a second synchronous link timed by a second clock. A device for justifying the bit stream at regular intervals includes a buffer memory. Respective pointers supply buffer memory write and read addresses. A value indicating how full the buffer memory is is calculated and compared to first and second threshold values to produce a justification command signal. The first and second variable threshold values are determined according to the phase difference between the header of a row received from the first link and the header of a row sent at the same time on the second link. The device finds an application in gateways at the input of and in telecommunication networks using the synchronous digital hierarchy.
