Failures are localized through the use of a Tandem Connection along a segment of a transmission path (P) to be monitored, non-intrusive intermediate Tandem Connection monitors (M), and temporary Tandem Connection sources created along the path segment in the case of a failure (F) in order to forward information about the fault location at least in downstream direction but preferably also in upstream direction.

This function creates a valid tandem connection signal and insert therein a failed link identifier (TTI). The network element (N4) terminating the tandem connection generates an alarm report including the failed link as indicated by the failed link identifier.

A structured method of matching schemas that uses multiple levels of ontologies is disclosed. The method maps functions of a target system to a process ontology and maps functions of a source system to the process ontology to produce a first mapping of target functions and source functions using the process ontology.

Then, the method maps the target function parameters to a concept ontology and maps the source function parameters to the concept ontology to produce a second mapping of the target function parameters and the source function parameters using the concept ontology. This second mapping is enhanced by mapping the target function parameters to a data-type ontology and mapping the source function parameters to the data-type ontology. This produces an enhanced second mapping of the target function parameters and the source function parameters using the data-type ontology. This enhanced second mapping can be the resultant output to be used in subsequent processing.
