Abstract: La présente invention concerne un noeud de réseau et un procédé d'affectation dynamique de largeurs de bandes pour des sessions télécommunications intranodales et internodales, l'invention consistant en un suivi de l'utilisation des ressources, aussi bien au niveau du châssis de matériel de ligne qu'au niveau de l'ensemble du système. Selon une réalisation, l'affectation dynamique de largeurs de bandes se fait par conférence multimédia entre abonnés d'un même autocommutateur privé (PBX). Si l'utilisation des ressources au niveau de l'un ou des deux châssis de matériel de ligne participant à la session intranodale atteint ou dépasse un plafond défini, on déclenche une nouvelle affectation des largeurs de bandes. De façon analogue, dès que le réseau de commutation d'un autocommutateur privé (PBX) atteint un plafond susceptible de bloquer l'ensemble du système dès une quelconque adjonction de session, on réalise une nouvelle affectation des ressources du système de façon à libérer de la largeur de bande. Les plafonds d'utilisations sont de préférence gérés par modifications adaptatives heure par heure et/ou au jour le jour. Selon la réalisation préférée, c'est une hiérarchie des classes de services qui sert à déterminer celles des cessions qui seront soumises à réduction de largeurs de bandes.

Title: Multiple call handling in a call center
Inventor: EDWARDS THOMAS J
IPC: H04M3/523
Filed: 1999-04-07
Abstract: The invention provides a method and system for indefinitely queuing telephone calls in a call center independent of the telephone instrument deployed in the call center. The system includes a plurality of call center telephones, an Automatic Call Distributor (ACD) connected to the call center agent telephones and a Computer-Telephony Integration (CTI) link connected with a multi-call handling (MCH) server having multiple call handling (MCH) application and a data repository. Call center technicians create a first new route point and a second new route point in the ACD using the ACD's configuration program. A client application pinning on the MCH server monitors telephone calls to the plurality of call center agent telephones through the CTI link. In response to a command from the client application of a call queue request for a call on a particular agent telephone, the MCH application running on the MCH server creates an index for the call, sets a timer for a duration less than the default call timeout period for the ACD, and directs the ACD to transfer the call in the first new route point. Prior to expiration of the default timeout period, the MCH application directs the ACD to transfer the call to the second new route point. The data repository retains the index for each call processed by the MCH  application. Storing the unique index for each call allows the MCH application to keep track of each call and enable the MCH application to retrieve a particular call, providing the agent with the ability to selectively retrieve or discard parked calls. The invention is also applicable to robotic call servicing applications that need to park calls and retrieve them. In such embodiments, the MCH application receives instructions from the robotic application rather than the client application.
Patent CA-2271296-A1 (CA)
Title: Electrical switching apparatus with push buttons for a modular operating mechanism accessible through a cover plate
Inventor: PHILLIPS NORMAN JOSEPH
IPC: H01H3/30
Filed: 1999-05-07
Abstract: Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided. Both indicators are pivotally mounted in a face plate pinned to the side plates and are connected to the operating mechanism by wireforms. The close and open push buttons snap out to a common shaft and have actuating fingers which trigger releases in the operating mechanism. The close rotating shafts are journaled solely in confronting apertures in the side plates. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners. Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.
