<p>A serial interface (IFl, IF2) is intended for being connected to data communication equipments in a communication network and is adapted to transmit and/or receive streams of serial data blocks. This serial interface (IFl, IF2) comprises i) a detection means (DM) for reading at least partly each received stream data block to detect a parity data included in each data block, ii) a control means (CM) for checking the parity of the data contained in each received stream data block (excepted the associated parity data) in order to deliver a computed parity data, iii) a first storing means (Ml) for storing a value representative of the number of parity failures, and iv) a processing means (PM) for comparing each detected parity data to the corresponding computed parity data, in order to deliver a comparison data representative of a parity success or failure, and, in case of comparison data representative of a parity failure, to increment by one the value stored into the first storing means (Ml) and then to carry out a new parity comparison relative to the next stream data block.</p> |
