  • Patent number: 5832196
    Abstract: The invention is a generalized process for dynamically restoring traffic in the event of an outage in a telecommunications network. A Centralized Processing System (CPS) receives alarms from communications ports of diverse network equipment (DNE) elements. The CPS then proceeds to analyze and correlate the alarms in an effort to isolate the location of the outage. In doing so, the CPS utilizes a Network Topology database that is preferrably updated in real-time with topology data obtained directly from the DNE network. The CPS will then identify and prioritize all traffic-bearing trunks impacted by the outage. The CPS then generates and implements a restoral route for each impacted trunk by issuing appropriate reroute command to the DNEs. If a DNE responds with an indication that a command failed and that its particular restoral segment is not possible, the CPS updates Network Topology database to indicate this segment as unavailable and proceeds to generate another restoral route.

  • Patent number: 5802144
    Abstract: A method and related system dynamically determines the location of a network outage in a telecommunications network. A plurality of alarm generating network equipments are located at spaced sites along the network. Alarms are generated upon the detection of problems with a signal passing through continuous signal trunks connected between the alarm generating network equipments. The alarm data from the alarm generating network equipments is connected at a single point. Network topology data is stored in a database, defining the relative locations of the alarm generating network equipments in the network and their respectively connected trunks. The alarmed equipment ports are correlated with respective connected alarmed trunks from data obtained in the database as well as collected alarm data. The alarmed trunks are analyzed for identifying the corresponding minimum number of alarm generating network equipments that exist between the alarmed trunks thereby defining effected inter-equipment trunks.

  • Patent number: 5737319
    Abstract: A system and method for dynamically determining the physical connection topology between diverse network elements (DNEs) within a communication network. Each DNE is audited on a periodic basis to determine the arrangement, configuration, cross-connection, and alarm status of each communication port within each DNE in the communications network. A topology database is maintained with such baseline information. Each DNE is configured with at least one mismatched port. Mismatched ports are cross-connected with communication ports within DNEs so that signal mismatch alarms are generated by communication ports coupled with the mismatched ports in other DNEs. Signal mismatch alarms are collected and processed so that connectivity status may be derived based on the baseline data, expected alarms, and the receipt of such alarms or lack thereof. A topology database is continuously updated to reflect such derived information.

  • Patent number: 5734811
    Abstract: A system and method are provided to diversely respond to changes in network topology and segment availability that occur between the time a restoration pre-plan is developed and the time it is executed. Changes that have occurred during this time are detected when the pre-plan is implemented. Dynamic responses to these network changes are manifest as real-time adjustments to the pre-plan during its execution in the form of a segment substitution or a segment swap.
