Abstract

Autocommutateur téléphoniques à réseau de commutation électromécanique (matrices de relais à contacts sous tubes scellés, notamment) et architecture modulaire (plusieurs groupes de lignes identiques) avec commande centralisée électronique (en particulier par calculateurs). Chaque groupe comporte 224 lignes et 32 circuits (joncteurs, envoyeurs, récepteurs...) ayant acces à chacune des n mailles (alimenteurs/connexions métalliques L1...n) prévues en fonction du trafic, par l'intermédiaire de deux étages de commutation B-C. Ce réseau est commandé par deux microprocesseurs (type Intel 8080) fonctionnant en partage de charge et connectés chacun à un explorateur de lignes LS1-2, un explorateur de mailles et de circuits LPS1-2 et un marqueur de groupe MK. Les calculateurs centraux commandent un troisième étage permettant la connexion d'une maille L à la ligne appelée ou au circuit requis du même groupe ou de tout autre groupe. Application aux centraux publics ou privés de moins de 4 000 lignes.Telephone PBX with electromechanical switching network (relay matrices with contacts in sealed tubes, in particular) and modular architecture (several groups of identical lines) with electronic centralized control (in particular by computers). Each group has 224 lines and 32 circuits (trunks, senders, receivers ...) having access to each of the n links (feeders / metal connections L1 ... n) provided according to the traffic, via two stages of BC switching. This network is controlled by two microprocessors (Intel 8080 type) operating in load sharing and each connected to an LS1-2 line explorer, an LPS1-2 mesh and circuit explorer and an MK group marker. The central computers control a third stage allowing the connection of an L link to the called line or to the required circuit of the same group or any other group. Application to public or private exchanges with less than 4,000 lines.
