  • Publication number: 20040246949
    Abstract: A system for transporting public switched network (PSTN) terminated signaling across an Internet protocol (IP) network includes a gateway between the PSTN and the IP network. The gateway receives a telephony signaling message from the PSTN and determines if the telephony signaling message maps to an IP signaling message. If the telephony signaling message does not map to an IP signaling message, the gateway packages the telephony signaling message in a special IP signaling message for transport over the IP network. If the gateway receives a special IP signaling special message, the gateway unpackages the telephony signaling message from the special message for transport over the PSTN. If the gateway receives DTMF signals from the PSTN, the gateway translates the DTMF signals to digits and packages the digits in a special IP signaling message for transport over the IP network. The gateway also packages the DTMF signals in an IP media transport protocol message for transport over the IP network.

  • Publication number: 20040071280
    Abstract: Disclosed is a system that prevalidates service orders that are placed by an inter exchange carrier with a local exchange carrier for connection of the inter exchange carrier with a business customer. An integrated prevalidation system and service order system is disclosed in which prevalidation requests are performed using the data that is entered for the service order. Prevalidation responses are then used to ensure that the order will be correct when submitted, thereby avoiding, the necessity for expensive supplemental orders. Further, the present invention allows for stand alone prevalidation requests which enable a provisioner to determine availability of circuits, and to determine location information and equipment identification directly from the LEC databases. Further, the present invention is capable of reconciling the database of the inter exchange carrier with the database of the LEC to avoid submission of incorrect service orders.

  • Publication number: 20040042607
    Abstract: A method and system for providing intelligent network control services in IP telephony, wherein the system includes a location manager and an IP telephony proxy server. The location manager includes an interface to a legacy telephony service control entity and the IP telephony proxy server includes an IP interface to the location manager. If the IP telephony proxy server requires intelligent network services, then the IP telephony proxy server sends an IP telephony session initiation request to the called party at the location manager. The location manager uses the information to query the legacy telephony service control entity for routing information. When the location manager receives a routing response from the service control entity, the location manager maps the response to an IP telephony session control message back to the IP telephony proxy server.

  • Patent number: 6512818
    Abstract: An approach for processing voice calls over a packet switched network as to efficiently utilize the functionalities of a Voice Response Unit (VRU). According to one embodiment, a call originator, acting as a User Agent Client in accordance with the Session Initiation Protocol (SIP), issues messages to establish a first call-leg with the VRU. The VRU performs digit collection to obtain information to authenticate the call originator and to authorize the voice call. Based upon the issued messages from the call originator, the VRU establishes a second call-leg with the call terminator. The VRU is released from the voice call after binding the call-legs to connect the call originator to the call terminator.

  • Patent number: 6493116
    Abstract: A fiber optic communications link having PMD characterization across multiple optical channels to identify PMD problems. The communications link has adaptive PMD controls employed along the optical link, whereby PMD phenomena detected by instruments, such as PMD compensators, are interpreted as being either attributable to perturbation of fiber characteristics at large, or by failure of PMD equipment along the link. The present invention avoids taking unnecessary control or maintenance actions upon PMD related controllers and compensators. PMD notifications from various PMD compensators are correlated to identify which portion of the link has undergone a change in polarization characteristics to further identify PMD related errors and problems.

  • Patent number: 6404733
    Abstract: In a telecommunications network provisioned with a distributed restoration scheme, to determine the reactions and responses of the network while the network is “live” or operational, an exercise information message is provided to the network for presenting a simulated failure or failures thereto. This exercise information message is broadcast to all of the nodes of the network so that every node is aware of the simulated failure scenario. Modified DRA messages that indicate that they are exercise only messages are used by the nodes for executing the exercise restoration process. Such exercise restoration process will proceed as if an actual failure has occurred with the notable exception that no actual cross-connections will be made. Certain functionalities are provisioned to the nodes to allow the exercise restoration process to be aborted if a real failure is detected or upon the expiration of a timer.

  • Patent number: 6404871
    Abstract: Terminating number screening to block portable billing products from terminating to a designated high fraud domestic or international terminating numbers. When a call is placed and it is billed to a portable billing product, the dialed digits of the terminating number is verified against the terminating number screening database. If the sequence of dialed digits is found in the terminating number screening database, the call is denied. The caller is then informed that they cannot place a call to this destination and asked if there is another terminating number they wish to call. If the sequence of dialed digits is not found in the terminating number screening database, the call is allowed to process without interruption. The purpose of this functionality is to protect the Operator Service network from repeated fraudulent calling to individual telephone line numbers either international or domestic.
