Endstationssynchronisierungsanordnung in einem digitalen asynchronen Übertragungsnetz

摘要

This synchronisation method for terminals connected to a so-called asynchronous transmission mode telecommunications network, including means (7) for filtering the transmission jitter introduced by such a network and affecting the rate of reception, via the said terminal, of the data routed through this network, and for slaving the frequency of a local clock signal delivered by a local clock internal to the said terminal, to that of the signal output by the said filtering means, includes a buffer memory (MTB1, MTB2), written with the said data, at their rate of reception by the said terminal, and means (5, 5') for reading this buffer memory, at the rate of the said signal output by the said filtering and slaving means, and with a delay, with respect to the writing, determined so as to minimise the risks related to the bit under-rate in the restoring of the data on completion of this reading, during the reaction times of the said filtering and slaving means, whilst remaining within an acceptable margin as regards the delay in the restoring of these data.
