Abstract: A high speed data queuing and retrieval system includes, in a lower tier, multiple storage devices for storing items for subsequent use by a requesting process, and multiple select devices for retrieving selected items in a pre-specified order from a corresponding storage device according to a requesting process, and, in an upper tier, multiple locally accessible storage devices for temporarily caching those items selected from the lower tier, and a select device for retrieving the selected items from the local storage device and feeding the requested items to the requesting process in a predefined sequence according to the request. The retrieval of the requested items from the local storage device is performed independent from and at a greater speed relative to the temporary caching of the selected items in the local storage device.

Abstract: A system and method for Enhanced Overflow Call Processing redirects calls which cannot be completed to alternate terminations. An originating switch queries a network database for an alternate termination for the call each time the originating switch detects that the call cannot be completed to the current termination. The network database determines the alternate termination for each query using a hierarchical set of multi-branch overflow statements which are configured by the user. A set of overflow statements is selected by the network database based on the original termination of the call. The set of overflow statements is searched hierarchically until an active overflow statement is found. This overflow statement then controls all queries relating to that call. The reason the call was not completed is used to select either an alternate termination to which the call is to be routed or a particular treatment, such as a busy signal or network message, which is to be applied to the call.

Abstract: The present invention advanced voice application system takes advantage of information, or attributes, built into a telecommunications network to determine the risk that a call is a fraudulent call in a voice recognition and verification system. To achieve this end, information relating to the telecommunications network are stored in a database as various risk factors. Thus, depending on the type of risk factors associated with a particular call, the risk assigned to that call can be raised or lowered so that the network would not reject a valid caller even though the voice pattern of the caller does not match exactly with the prestored enrolled voice print of the caller. Such risk assessment allows the management of the network to tighten the security of the system without overburdening the caller with questions and also permits calls to be completed for valid subscribers that otherwise would have been rejected.

Abstract: A centralized restoration system utilizes preferred routing tables to identify an optimal restoral path for restoring a network from a failure. The preferred routing tables are constructed prior to the failure of the network. This pre-construction of the preferred routing tables prior to network failure substantially diminishes the computational and temporal requirements needed to restore the network at the time of failure. The centralized restoration system is able to account for changes in network topology and configuration. The centralized restoration system builds the optimal restoral path on a link by link basis and examines the availability of links prior to adding the link to the optimal restoral path. Unavailable links are not added to the restoral path.

Abstract: A method of and system for emulation of multiple subscriber profiles on a single telephone in a telecommunications network. An identified group contains more than one subscriber profile. The system is activated when a user selects a subscriber profile to be associated with the telephone being used. In response to the selection, the system determines whether the selected subscriber profile is within the group. If it is, the system associates the selected subscriber profile from the group with the telephone, such that the telephone emulates the selected subscriber profile. If the selected subscriber profile is not within the group, the subscriber profile associated with the telephone is unchanged.

Abstract: A system, method and computer program product are described, by which a user, through a control interface in a subscriber interface device, requests from network intelligence both transport network bandwidth and type of service line mode as part of call setup. An improved system by which requests to change access line mode and bandwidth are communicated over transmission facilities via D channels through local switch fabric to local or remote network intelligence is detailed. Connections over the transmission facilities, established between user B channels and B channels of transport bandwidth or between user B channels and the Stat Mux function, are described. An improved system is summarized, in which connections directly to transport bandwidth support point-to-point n B+D upstream and m B+D downstream service, and connections via stat mux allow connectionless traffic to share a portion of the transport bandwidth on an as needed basis.

Abstract: A method and system for creating and sending call disposition messages. When a calling card call is validated by the telephone network which issued the card, the card issuing network can request a call disposition message. In response to validation of the call, a billing detail record is generated and stored. When the call is completed. an operator service record is generated. The operator service record and its corresponding billing detail record are matched with each other, then merged to form a merged operator services record. The merged operator services record is processed to add pricing information. If the card issuing network had requested a call disposition message, the merged operator services record is sent to a gateway coupled to the card issuing network where it is reformatted to create a call disposition message. The call disposition message is then sent to the card issuing network.

Abstract: To ensure that the distributed restoration process of a DRA provisioned network proceeds only in response to true failures, the present invention DRA network provisions to each of the ports of the nodes a timer mechanism for ascertaining whether an alarm is a genuine alarm. This is done by presetting the timer with an expiration period so that an alarm is validated as a failure only upon the expiration of the timer. When validated, the value of a counter is incremented. The value of the counter is reflective of the sum of validated alarms, and is compared against a preset threshold value. And it is only when the value of the summed validated alarms exceeds the preset threshold value would the DRA process be initiated. When a validated alarm ceases, the reverse process takes place. That is, the ending of the alarm has to be validated by another timer, which could be the same timer as used for validating an alarm.

Abstract: A restoral route generation process combines elements of a pre-plan methodology with a dynamic route generation methodology. The resulting hybrid approach quickly produces a restoral route in real time that has a minimal associated cost. The hybrid approach pre-generates sub-routes that are combined to produce a restoral route. The combining of the sub-routes takes place dynamically in response to a network failure. The hybrid approach may interactively operate to generate restoral routes for each trunk in the network that is affected by an outage.
