  • Patent number: 5796718
    Abstract: A method and system for providing intelligent protection against access line failures in a telecommunications system including customer premises equipment connected by a plurality of access lines to a data transport network. The system detects a line fault on a first access line at the customer premises equipment. In response to the detection of a line fault, the system sends a query to the network management system of the data transport network to determine the origin of the line fault. The system receives a response to the query from the network management system and uses the response to deal with the line fault in an intelligent manner. Whenever the network management system responds to the query by indicating that the line fault originated in the data transport network, the system maintains the connection and waits for the failure to be resolved.

  • Patent number: 5796723
    Abstract: A system and method for performance monitoring of a telecommunications network that uses a layered performance monitoring structure. First, the monitoring points within the network are identified according to a customer request. The customer request is used to generate a service provisioning request, which indicates the path endpoints and the desired level of service. If the service is a digital data service and is supported for monitoring purposes, the network elements closest to the path endpoints are identified as primary monitoring points and activated, and based upon the desired level of service, a number of intermediate secondary points along the path are also identified but not activated. If the service is not a digital data service but the customer desires monitoring, then monitoring points are similarly identified and activated. Second, an end-to-end threshold is set for each service requiring thresholding per the service provisioning request.

  • Patent number: 5787150
    Abstract: Method and apparatus allow a caller to contact a called party with a collect call whether or not the called station is answered or is busy. When the caller dials a collect call access code, the call is routed to a messaging platform which collects the call information and attempts to complete the call. If there is no answer or if the called station is busy, the messaging platform retains control of the call and automatically prompts the caller to enter a name and a message to be delivered to the called party. After the name and message have been entered, the caller is given a confirmation number, if desired, which allows the caller to determine whether the called party has received the message. The messaging platform repeatedly attempts to deliver the message by calling the called party. Upon the call being answered, the messaging platform identifies the caller and prompts the called party to accept or refuse the collect message.

  • Patent number: 5778184
    Abstract: The system and method of analyzing the performance of the network is described herein. The system operates by receiving a first problem alert signal (PAS) from a monitoring point associated with a network facility. The PAS indicates a potential problem with a network facility in a path entity. The system then determines whether the path entity includes distinct line entities. If the path entity includes distinct line entities, then the system determines whether a second problem alert signal has been reported by a monitoring point associated with a network facility in a line entity. The system then initiates a problem handling process for a line entity and suppresses the first PAS if a second PAS has been reported for the line entity. If no problem alert signals have been reported for the line entity, the system initiates a problem handling process for the path entity and reports the first PAS to a higher layer in the network management system.
