Method of detecting a loss of synchronisation in a digital communications network, and terminal for implementing the method

摘要

Method of detecting a loss of logic synchronisation between a sending terminal linked by a digital data channel (19) to a receiver terminal, in which - the sender sends a defined sequence of sending code words (25) into a synchronisation channel (29), - the receiver reads a sequence of reception code words (66) identical to the sending sequence (25) and compares the sending and receiving code words, - in the event of lack of identity in sending (25) and receiving (66) code words, the receiver generates a loss of logic synchronisation signal (8) in order to resynchronise the two terminals. Application to transmission of coded speech. IMAGE
