Usable
Usable
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.
Active
Active
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.
Near End and Far End Rx Failure
Failure
Failure
This condition indicates that a reason was not given.
LIF
Loss of IMA Framing
This condition indicates a loss of IMA framing.
LODS
Link Out of Delay
Synchronization
This condition indicates a link out of delay
synchronization.
Misconn
Mis-connectivity
This condition indicates that mis-connectivity has been
found as a result of a test.
Inhibit
Inhibit
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.
Blocked
Blocked
This condition indicates a transition into the unusable
state without loss of ATM layer cells.
Fault
Fault
This condition indicates a fault on the link or in the link
protocol.
FeTx UU
Far End Transmit Unusable
This condition indicates that the Far End transmitter is
in the unusable state.
FeRx UU
Far End Receive Unusable
