  • Patent number: 7061923
    Abstract: A resource management system for an intelligent communications network having one or more distributed service nodes, each service node for providing services relating to an event received at a network resource associated with a service node. The system comprising a first processing tier comprising one or more local execution environments located at a node, each execution environment including a mechanism for instantiating one or more service objects capable of performing event services at a first local execution environment, and, for generating status information relating to executing service objects; and, a second processing tier associated with a service node and including a system processor for tracking status and availability of service objects and local execution environments.

  • Patent number: 6330079
    Abstract: A platform for use in a communications system integrates voicemail and faxmail functionality. The platform collects, stores, and retrieves voicemail and faxmail messages for numerous subscribers. Each subscriber accesses his or her account with, for example, a single telephone number assigned to the subscriber. The integrated voicemail and faxmail platform collects, stores, forwards, distributes, saves, deletes, and retrieves voicemail and faxmail messages for the numerous subscribers based on the single number. The platform also provides capability for enhanced features such as automatic callback to individuals who leave a message for a subscriber, broadcasting of fax messages to multiple recipients, and the creation and management of distribution lists for voicemail and faxmail messages.

  • Patent number: 6078586
    Abstract: A network architecture and service platform for providing virtual private network services ("VPN") over an ATM network. The architecture provides services for voice, video, and data traffic among multiple VPN customers over a shared ATM network by implementing intelligent control devices to perform enhanced processing of ATM call setup messages, including validations and routing translations. Hierarchical routing mechanisms provided by ATM, along with customized customer addressing schemes, are used to overlay customer VPNs as higher-level networks onto the shared ATM network. The control devices translate customer ATM VPN address to internal ATM network addresses. The ATM switch network then performs lower-level network processing, using internal network addressing, to setup a virtual connection for a VPN call. The intelligent control devices may also explicitly state the end-to-end route.
