Title (EN) CIRCUIT ARRANGEMENT TO ALIGN THE PCM GROUPS ENTERING A COMMUNICATION BRANCH POINT WITH ANOTHER
(FR) AGENCEMENT DE CIRCUIT PERMETTANT L'ALIGNEMENT, LES UNS PAR RAPPORT AUX AUTRES, DE GROUPES MIC ENTRANT EN UN POINT DE BRANCHEMENT DE COMMUNICATION
Abstract: front page image
(EN)The circuit arrangement is designed to manage bidirectional transmission of PCM channels and includes the presence of a transmitting section (ST), a receiving section (SR) and a basic time generating unit (TBG). The transmitting section (ST) encodes the PCM signals according to the regulations foreseen by the Manchester II code, and also introduces a violation of the said regulations each time it receives a synchronizing pulse (S¿1?) from the said basic time generating unit (TBG). The receiving section (SR) decodes the received signals, extracts the synchronizing signal (S¿r?) and outputs the PCM signals with a lag that is a function of the temporal relationship between the synchronizing signal (S¿r?) extracted from the data stream and the synchronizing signal (S¿1?) output by the basic time generating unit (TBG).
(FR)L'agencement de circuit est conçu pour gérer la transmission bidirectionnelle de canaux MIC et inclut une section de transmissison (ST), une section de réception (SR) et une unité génératrice de temps de base (TBG). La section de transmission (ST) code les signaux MIC selon les règles prévues par le code Manchester II, entraîne une infraction auxdites réglementations chaque fois qu'elle reçoit une impulsion de synchronisation (S¿1?) de ladite unité génératrice de temps de base (TBG). La section de réception (SR) décode les signaux reçus, extrait le signal de synchronisation (S¿r?) et sort les signaux MIC avec un retard qui est fonction de la relation temporelle entre le signal de synchronisation (S¿r?) extrait du flot de données et le signal de synchronisation (S¿1?) sorti par l'unité génératrice de temps de base (TBG).
