States and Failure Conditions (Continued)
Failure Condition
This condition indicates that the link is ready to be used
for receiving ATM layer cells and it is awaiting the FE Tx
to be Usable or Active before moving into the Active
state.
The link has been synchronized with the other receive
links already in the Usable or Active state.
The IMA receiver considers the link to not be in a data
round-robin state.
This condition indicates that the link is capable of
passing cells to the ATM layer.
The IMA receiver considers this link to be in a data
round-robin state.
This condition indicates that a reason was not given.
This condition indicates a loss of IMA framing.
This condition indicates a link out of delay
synchronization.
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 some locally defined application or
implementation dependant reason.
The link may be used for testing.
This condition indicates a transition into the unusable
state without loss of ATM layer cells.
This condition indicates a fault on the link or in the link
protocol.
This condition indicates that the Far End transmitter is
in the unusable state.
This condition indicates that the Far End receiver is in
the unusable state.
This condition indicates that there is no current failure
condition.
