A synchronizing device for terminal equipment in an asynchronous transfer mode telecommunications network, comprising a device (7) for filtering the transfer jitter which is introduced by such a network and affects the network-routed data reception rate through said equipment, and for matching the local clock signal frequency supplied by a local clock within said equipment to the frequency of a signal output by said filtering device. The synchronizing device comprises a buffer memory (MTB1, MTB2) into which said data are entered as they are received by said equipment, and a device (5, 5') for reading said buffer memory as said signal is output by said filtering and matching device, with a delay relative to the entry of said data which is determined in such a way as to minimize any risk arising from an insufficient restoration flow of read-out data during the response time of said filtering and matching device, while keeping within an acceptable data restoration delay margin. |
