Values are as follows: 'other' indicates a vendor-specific operational status. 'up' indicates that the pseudowire is ready to pass packets. 'down' indicates that pseudowire signaling is not yet finished, or indications available at the service level indicate that the pseudowire is not passing packets. 'testing' indicates that AdminStatus at the pseudowire level is set to test. 'dormant' indicates that the pseudowire is not in a condition to pass packets but is in a 'pending' state, waiting for some external event. 'notPresent' indicates that some component is missing to accomplish the setup of the pseudowire. It can be a configuration error, incomplete configuration, or a missing H/W component. 'lowerLayerDown' indicates one or more of the lower-layer interfaces responsible for running the underlying PSN is not in OperStatus 'up' state.
