Down indicates that a card or equipment in a network element has failed. A Card or Equipment failure causes all PTPs on the device to fail to pass traffic.
The symptomatic events for Card Down or Equipment Down include:
Alarm from a network element indicating Card or Equipment failure
Remote Failure Indication (RFI) on PTP objects that represent the end points on which the client connections that pass through the network element enter and exit the network. Note that the Optical Transport Manager interprets RAIs (Remote Alarm Indications) and RFIs from digital links as RemoteIndications.
