Down indicates that the 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.
Loss of Signal (LOS) or Loss of Frame (LOF) on the PTPs that are directly connected to the PTPs contained in the failed Card or Equipment.
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.
LOS and/or LOF for downstream PTP objects that are directly connected to ports on the failed Card or Equipment.
