Abstract
Improvements in private telephone installations by electronic switch with direct connection to the network and which fulfills the dual function of auto-switch and local intercom equipment, comprising an operator position and a plurality of satellite positions of which part is at least equipped with means of access to external communications, each position of the equipment being provided with local intercommunication means, characterized by the fact that said installation comprises the combination of: as many network access circuits as there are external telephone lines connected to the equipment, each one comprising these circuits a device to relay for connection to the network and as many access blocks of positions as there are positions equipped with means of access to external communications, blocks connected in parallel on the device, to relay by conversation conductors and control conductors switching; a plurality of local communications control circuits, each of which comprises a relay device for local interconnections and as many communication path blocks as there are positions in the equipment, blocks connected in parallel by said relay device by conversation leads and communication command leads; a call dialer device and an occupancy dialer device; as many marker connection circuits as there are positions; sets of conversation and numbering conductors that interconnect each of the positions with one of the network access blocks, one of the communications route blocks and one of the dialer connection circuits; sets of switching and signaling control conductors that interconnect the network access block, the communications path block and the marker connection circuit in each group of these blocks associated with a position, part of these conductors being connected to call and busy dialers; and, signaling and control conductors between said call dialer and said dialer connection circuits, between said occupation dialer and these dialer connection circuits, these relay devices and equipment positions.
