The communications are formed by cells carried by an incoming asynchrouous time-based multiplex (XE), and which are processed in order to deliver an outgoing asynchronous time-based multiplex (XS). Each incoming cell is stored in a buffer memory (MT) at an address (Add) corresponding to its actual time of retransmission (t) on the outgoing time-based multiplex (XS). It consists in comparing the number of cells (N) of the same communication which are stored in the buffer memory (MT) and which have not yet been transmitted at the arrival time of an incoming cell belonging to the said communication, with a maximum number (NM) attributed to the communication and, in the case in which the first number exceeds the second, in not making provision to retransmit the said incoming cell. <IMAGE> |
