Abstract

The proposed method is to be used in a mechanism, such as described in European Patent Application No. 854500266, wherein the data on the links of the telecommunication network are sent in frames beginning with a framing medium flag MF and comprising n subframes. Each subframe comprises Ns bits and some padding bits of the packet type which are added to form a frame of Nc bits. The link parameters n, Nc and Ns depend upon the transmission speed of the link. Fig. 1 shows the configuration of the frames and subframes. For each link, a master clock, which is the image of the link speed, a T-Clock with T=125 microsecond in the preferred embodiment, and the medium flag rate, which is a maximum of one MF per 256 bits, are provided to the circuit shown in Fig. 2, which is located at the transmit side of the link.
