Method and device for the numeric control of the buffer and of a phase-locked loop for asynchronous networks

Abstract From the Canadian patent

A method and device is described for the numeric control of buffer and phase-locked loop for the recovery of the synchronism and the optimized management, over communication networks having a high jitter like e.g. networks in which , the, ATM mode (Asynchronous Transfer Mode) is used. The innovation resides in the buffer management which is carried out according to the input phase statistic characteristics (in part known a priori and in part measured by the system) as well, as to its measured value (which is equivalent to the buffer filling level) thus, introducing the concept of statistic pointers. This allows an optimal management, thereof and also permits to control the buffer …
