  • System and method for fault detection and recovery
    Patent number: 7386764
    Abstract: An apparatus and method for automatically detecting and recovering from a fault in a microprocessor-based system. The apparatus and method utilizes a leaky bucket routine and an event handler procedure. The method may further use Object Oriented techniques that abstracts differences between hardware and software faults to allow for the development of a common framework.
    Type: Grant

  • Method of controlling parameter downloading from a communication switching system to customer stations
    Patent number: 5355404
    Abstract: A method for use by a switching system in controlling the downloading of parameters to customer stations. The notification of stations due to a change in a configuration group is performed at a controlled rate and accordingly any reduction in call processing due to the parameter downloading of customer stations is limited. The controlled rate notification is performed in accordance with two lists that are maintained by the switching system and used to track the active/inactive status of customer stations and to order the notification of active stations and the status checking of inactive stations.
