A link state indicating that the link is ready for transmitting or receiving ATM cells in the specified direction, either Tx or Rx. Each
direction may enter active state asynchronously.
Discrepancy between the actual and desired characteristic of an item. An anomaly may or may not affect an item to perform a
required function.
Application Programming Interface
This is an IMA configuration scheme. In this configuration mode, the physical links that are assigned to an IMA group are not
required to be configured in both Tx and Rx directions. That is, some of the physical links may be configured to use both directions
while others may only use one direction (Tx or Rx).
This is an ATM traffic transfer mode of an IMA group. In this mode, the physical link can be used to transfer data in one direction and
does not care the other direction’s Tx and Rx state. That is, when the Tx state of end A and Rx state of end B have both entered
active state, end A starts to transfer data to end B and end B starts to receive. In this case, end A does not care whether end A’s Rx
state is active or not and end B does not care whether end B’s Tx state is active or not.
Asynchronous Transfer Mode
Cells (ATM formatted) that are exchanged between ATM layer and IMA sublayer. It is also called application data.
This is a group state indicating that the group has been inhibited from transiting into OPERATIONAL state for some administrative
purposes.
This is a group state indicating that the group has rejected the group parameters proposed by the FE IMA group.
This is a configuration where the transmit clocks of all the physical links within an IMA group are derived from the same clock source.
This is the data transfer method IMA used to deliver cells from ATM layer to multiple transmit links within an IMA group, or the data
play-out method that the IMA used to form a consecutive cell stream from multiple receive links within an IMA group.
A defect may be caused by successive anomaly of an item to perform a required function. The defect may or may not lead to main-
tenance action depending on the results of additional analysis.
Errored Seconds
Two communication entities are considered to be two communication ends. Mostly, one is called Near-End (NE) and the other is
called Far-End (FE).
This is a kind of OAM cell used by IMA layer. It is used to fill in the IMA frame when no cells are available at the ATM layer. Thus filler
cell is used for cell rate decoupling at IMA sublayer (like idle cell used in TC layer).
This is the state machine that determines the behavior of the IMA group.
This state machine controls when to exchange ATM layer cell between the ATM layer and the IMA layer
This refers to the Group Start-up and LASR procedures performed by the IMA unit to synchronize the activation of IMA links within
the IMA group.
This is used for checking the correctness of the ATM cell header.
