Abstract:
In a voice packet network having plural connectable endpoint nodes with plural trunks therebetween and a trunking alarm associated with each endpoint node, an alarm aggregation method comprising:detecting a first trunking alarm for each of the plural trunks associated with one of the endpoint nodes; detecting a second trunking alarm for each of the plural trunks associated with another of the endpoint nodes occurring during a period of time of the first trunking alarm; aggregating the first and second alarm condition to assist in determining a condition of the plural trunks between the plural connectable endpoint; selectively signaling an out-of-service condition of more than one of the plural trunks onto an outgoing T1/E1 connection coupled to the trunk by asserting an alarm; and determining if a number of the plural trunks for which an out-of-service condition is signaled is greater than a predefined threshold.
