Definitions

  • PBX backup systems connect lines directly to a telecommunications company's central office trunks during failure of a primary PBX system.
  • DEES Communications Engineering Ltd. 4130 148th Avenue NE, Redmond, WA 98052, sells a Powerfail Bypass Unit, having model numbers 154, 154A and A500, that automatically bypasses the PBX system and switches up to eight central office trunks to preselected stations during power failure at the PBX.
  • the DEES unit is normally controlled by the user's PBX or by a manual switch located on the unit itself.
  • the visual indicators 50 also indicate the backup PBX 14 is controlling signal transmissions to and from all associated critical extensions 16.
  • the red LED 54 is energized when all a contacts 47 associated with the corresponding remote switching station 26 are closed. If a remote switching station 26 fails to respond to the signal from the control unit 40 by illuminating the second visual indicator 54 after the control switch 49 is closed, the nonresponsive master or slave panels 44, 46 can be manually switched to close the a contacts 47 and establish the connection with the backup PBX 14.

Abstract

L'invention porte sur un système de reprise en cas de sinistre (10) d'un réseau de télécommunications, ce système fournissant un service de télécommunications à des installations d'abonnés lors de la défaillance d'un mode de fonctionnement normal du système. Certains équipements terminaux (15) d'installations d'abonnés considérés critiques pour le fonctionnement permanent d'un service d'affaires, sont raccordés à un PBX primaire (12) en mode de fonctionnement normal, et à un PBX secondaire (14) lors de la défaillance du mode de fonctionnement normal. Le système comprend également une unité de commande (40) comprenant un commutateur de commande à actionnement manuel (49) pour chaque bâtiment ou local renfermant un équipement terminal critique. Chaque commutateur de commande (49) est ouvert en mode de fonctionnement normal, et est fermé lors de la défaillance du mode de fonctionnement normal. Une station de commutation à distance (26) est raccordée de manière fonctionnelle à chaque commutateur de commande (49), au PBX primaire (12), au PBX secondaire (14) et à l'équipement terminal critique (15) associé au bâtiment ou local particulier. En fonction de la position du commutateur de commande (49), la station de commutation à distance (26) commute l'équipement terminal critique correspondant dans le système PBX primaire ou secondaire (12, 14).
