Link Out Of Delay Synchronization defect. The LODS is a link event indicating that the link is not synchronized with the other links
within the IMA group.

Near-End (local end)
This is a group state indicating that the group does not exist yet.
This is used as an event or a state indicating that a link is no longer configured within an IMA group.
Operations And Maintenance
Out of Cell Delineation anomaly. As specified in ITU-T Recommendation I.432 [30], an OCD anomaly is reported upon the occur-
rence of Alpha (α) consecutive cells with incorrect HEC, and it is no longer reported after detecting Delta (δ) consecutive cells with
correct HEC.
Out of IMA Frame anomaly
Out Of Frame
Group state indicating that the group has sufficient links in both Tx and Rx directions to carry ATM layer cells.
This is the link being used by the IMA unit to transmit and receive ATM cells. The IMA unit may use physical links in one or both
directions.
Minimum number of links required to be active in the receive direction for the IMA group to move into the Operational state.
Minimum number of links required to be active in the transmit direction for the IMA group to move into the Operational state.

Severely Errored Seconds
Stuff ICP cell. One of the 2 ICP cells comprising a stuff event.
This is a repetition of an ICP cell over one IMA link to compensate for timing difference with other links within the IMA group.
This is a group state indicating that the group is waiting to see the FE in Start-up.
This is a group transitional state, when both groups are in start-up and the FE group parameters have been accepted.
This is an IMA group configuration scheme. In this configuration mode, physical links that are assigned to an IMA group are required
to be configured in both Tx and Rx directions.
This is an ATM traffic mode of an IMA group. In this mode, the physical link can be used to transfer data only when the link’s NE’s Tx
and Rx and FE’s Tx and Rx are all in active state.
