States and Failure Conditions (Continued)
Failure Condition
This condition indicates that the link has been removed
from the group.
This transitional state ensures that the other end is still
not receiving ATM layer cells before it moves to the
Unassigned state.
This condition indicates that a fault has been detected
either on the link or in the link protocol.
This condition indicates that mis-connectivity has been
found as a result of a test.
This condition indicates that operation of the link is
blocked for a locally defined application or
implementation dependent reason.
The link may otherwise be used.
This condition indicates that the link is ready to be used,
it is awaiting the FE to activate its receiver before
sending any ATM layer cells.
IMA frames containing only filler cells are being
transmitted, but the link is not in a data round-robin
state.
This condition indicates that the link is capable of
passing cells from the ATM layer.
The IMA transmitter considers the link to be in a data
round-robin state.
This condition indicates that no information about the
link exists.
This condition indicates that the link has been removed
from the group.
This transitional state ensures that the other end is still
not receiving ATM layer cells before it moves to the
Unassigned state.
This condition indicates that the receiver has failed due
to the persistence of a defined defect.
Examples of defects are LCD, LIF, and LODS.
This condition indicates that a fault has been detected
either on the link or in the link protocol.
Allows a graceful transition into Unusable from Active
state without loss of ATM layer cells.
This condition indicates that a reason was not given.
