eMonitoringCTPSink — ETSI published formal attachments
An instance incorporates the monitoring capabilities of the trail termination sink function (TTm-Sk) defined at the path layer represented by the subclass of this class. The monitoring capabilities do not apply in case of unframed signals expected when the inherited attribute framedSignalMode is set to value 'inactive' A communicationsAlarm notification shall be issued if a Server Signal Fail (SSF) is detected. The probableCause parameter of the notification shall indicate serverSignalFailure. A communicationsAlarm notification shall be issued if a Far End Receiver Failure is detected. The probableCause parameter of the notification shall indicate farEndReceiverFailure (fERF) [3]. Detection of a fERF has no effect on the operationalState. Instances of the subclasses of this class may be used at the different PDH path layers to provide with performance data monitoring capabilities based on Frame Alignment Signal Errors (FASE) [8].
