  • Method and apparatus for sharing common capacity and using different schemes for restoring telecommunications networks
    Patent number: 8155515
    Abstract: A system and method for responding to a failure in a communications network. The failure is detected by a router, which then transmits data from the protection port. A signal is sent from the router to a optical cross-connect system indicating the failure and causing the optical cross-connect system to connect the protection port of the router to a working port of the OXC.
    Type: Grant

  • Method and system therefor for ensuring a true activation of distributed restoration in a telecommunications network
    Patent number: 6294991
    Abstract: To ensure that the distributed restoration process of a DRA provisioned network proceeds only in response to true failures, the present invention DRA network provisions to each of the ports of the nodes a timer mechanism for ascertaining whether an alarm is a genuine alarm. This is done by presetting the timer with an expiration period so that an alarm is validated as a failure only upon the expiration of the timer. When validated, the value of a counter is incremented. The value of the counter is reflective of the sum of validated alarms, and is compared against a preset threshold value. And it is only when the value of the summed validated alarms exceeds the preset threshold value would the DRA process be initiated. When a validated alarm ceases, the reverse process takes place. That is, the ending of the alarm has to be validated by another timer, which could be the same timer as used for validating an alarm.
