Title (EN) A DIGITAL TIME DIVISION SWITCHING ARRANGEMENT
(FR) DISPOSITIF DE COMMUTATION DE DIVISION DU TEMPS
Abstract: front page image
(EN)Digital time-division switching arrangement capable of interfacing with a plurality of PCM communication lines (1, 12) on one side and a separate plurality of transmission channels (1, 15) on the other side. A first processor (4, 40) primarily tracks call progress by scanning signalling bits indicating on/off hook state changes and a second processor (4, 41) controls the action of a time slot interchanger (1, 35) which both assembles and disassembles channel data and telemetry messages and establishes and breaks down calls while connecting appropriate service circuits (1, 29) to the communication lines (1, 12) during the progress of a call.
(FR)Dispositif de commutation de division du temps a affichage numerique susceptible d"etre connecte par interface a une pluralite de lignes de communication MIC (1, 12) d"un cote et a une pluralite de voies de transmission (1, 15) de l"autre. Un premier processeur (4, 40) suit essentiellement le deroulement d"appels en analysant les bits de signalisation indiquant les changements de situation raccrochements/decrochements et un second processeur (4, 41) commande l"action d"un echangeur de tranches de temps (1, 35) qui, a la fois, assemble et desassemble les messages par voie de transmission de donnees et par telemetrie et etablit le branchement et la coupure d"appels tout en connectant les circuits de service appropries (1, 29) aux lignes de communication (1, 12) pendant le deroulement d"un appel.
