Abstract
A time division multiplex link is used with successive frames each having a specified number of transmission timeslots. A first unit inserts ATM cells into a part of the timeslots which is allotted to the ATM flow intended for a second unit and other data into other timeslots allotted to the transport of at least one non-ATM flow intended for a third unit. The signals received are analyzed so as to search for synchronization with the cells of the ATM flow and to identify that part of the timeslots which is allotted to the ATM flow. This analysis comprises a synchronization test executed successively on subsets of timeslots within the frames until good synchronization is observed. The cells extracted from the timeslots of the identified part are then directed to the second unit, while the other data are directed to the third unit.
