100 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS
Tx LID—Transmit logical link ID: 0-31. This number reflects the local IMA ID.
Rx LID—Receive logical link ID: 0-31. This number reflects the remote IMA ID.
Operation Link Delay—The differential link delay referenced to the fastest link in
the same group.
Rx Test Pattern—The received test pattern received: 0-254; 255 indicates that no
pattern has been received.
Test Procedure—The status of the test procedure: disabled, operating, or link
failed.
Viewing IMA Group
Status
To view IMA status for a selected group, follow these steps:
1 From the Configuration Management menu, select [1] Manage Card.
2 From the List Card menu, select the number corresponding to the slot in which the
T1 UNI or E1 UNI card is installed to open the Group Menu.

Table 24 Possible IMA LInk Failure Status Conditions
Failure Description
link failure This is caused by LOS, AIS, OOF, or LCD.
LIF failure This is caused by LIF.
LODS failure This is caused by LODS.
Misconnected This is caused by bad IMA ID, bad link ID, or bad SCCI.
blocked This is caused by AFA, excessive delay, or mismatched protocol.
fault This is caused by bad M value, bad symmetry, bad offset, or
duplicate link ID.
far end Tx link unusable This is caused by the far end reporting Tx unusable in the ICP
cells.
far end Rx link unusable This is caused by the far end reporting Rx unusable in the ICP
cells.
no failure The link has no failure.
