Enable AIS-RDI Detection When selected, alarm indication signal (AIS) cells and remote defect
indication (RDI) cells are used to report connectivity failures at the
ATM layer of the PVC.
When deselected, AIS/RDI cells are disabled.
AIS cells notify downstream devices of the connectivity failure. The
last ATM switch then generates RDI cells in the upstream direction
towards the device that sent the original failure notification.
Down Count The number of consecutive AIS/RDI cells that cause the PVC to go
down. Valid values range from 1 to 60. The default is 1.
Up Count The number of seconds after which a PVC is brought up if no AIS/RDI
cells are received. Valid values range from 3 to 60 seconds. The default
is 3.
