Abstract
A device for the transmission of synchronous information by an asynchronous network, notably an ATM type network, where information elements are conveyed by packets of data bits between a transmitter unit and a receiver unit. Each of these packets is formed by an information cell comprising a header carrying an address and a useful field bearing the information to be transmitted. The transmitter unit and the receiver unit work with each other in a synchronous mode on the basis of respective plesiochronous local clocks. The device detects and compensates for a lengthy fading of transmission of the flow of information cells received by the receiver unit. The device also detects and compensates for a loss or insertion of cells in the flow of information cells received by the receiver organ. The device further reduces the jitter introduced by the asynchronous transmission of the information elements into the network and compensates for the relative plesiochronism of the local clocks of the transmitter unit and the receiver unit.
