1. A method in a network management layer for isolating a problem in a circuit path contained in a network, the circuit path including a plurality of network elements interconnected by a plurality of links having various transport levels, the method comprising the steps of:
- (1) receiving a first problem alert signal at a first signal transport level from a first monitoring point associated with a first network element in the circuit path;
(2) identifying a second problem alert signal at a second signal transport level, said second problem alert signal being generated by a second monitoring point associated with a second network element in the circuit path, wherein said first signal transport level is mapped into said second signal transport level;
(3) determining whether said network management layer has access to enough information to isolate the problem; and
(4) identifying a third monitoring point upstream of said first monitoring point that reports a third problem alert signal corresponding to said second problem alert signal.

Abstract
A system and method for isolating a problem in a network. Upon a report of error activity in a first signal transport level, a first layer in the network management system uses performance data to identify the highest signal transport level that exhibits simultaneous error activity. The first layer attempts to isolate the problem if it determines that it has access to enough information.

9. A method in a network management layer for isolating a problem in a circuit path contained in a network, the circuit path including a plurality of network elements interconnected by a plurality of links having various transport levels, the method comprising the steps of:
-
(1) receiving a first report of error activity at a first signal transport level from a monitoring point associated with a network element in the circuit path; (2) determining whether a second report of error activity has been received for a next highest signal transport level, wherein said first signal transport level is mapped into a second signal transport level; (3) repeating said step (2) until a highest signal transport level reporting an indication of error activity is identified; and (4) isolating the problem through analysis at said highest signal transport level. - View Dependent Claims (10)

11. A computer program product for use with a computer system, comprising:
-
a computer usable medium having computer readable program code means embodied in said medium for causing the computer system to isolate a problem in a circuit path contained in a network, the circuit path including a plurality of network elements interconnected by a plurality of links having various transport levels, wherein the isolation is effected in a network management layer, said computer readable program code means comprising; first computer readable program code means for causing a computer to effect a reception of a first problem alert signal at a first signal transport level from a first monitoring point associated with a first network element in the circuit path; second computer readable program code means for causing a computer to effect an identification of a second problem alert signal at a second signal transport level that produces a second problem alert signal being generated by a second monitoring point associated with a second network element in the circuit path, wherein said first signal transport level is mapped into said second signal transport level; third computer readable program code means for causing a computer to effect a determination of whether said network management layer has access to enough information to isolate the problem; and fourth computer readable program code means for causing a computer to effect an identification of a third monitoring point upstream of said second monitoring point that reports a third problem alert signal corresponding to said second problem alert signal. - View Dependent Claims (12, 13, 14, 15, 16, 17)
