IAGNOSTICS AND ERFORMANCE
Table 11 T1/E1 UNI with IMA Module Alarms (continued)
Alarm Meaning
Duplicated Offset Duplicated far end ICP cell
offset in this IMA group in an
IMA link.
Each IMA group assigns a
unique Transmit offset to each
link in the group. This alarm
means that a link received a
Transmit offset already
assigned to a previous link.
Some of the links are probably
misconnected.
Excessive Link Delay The link has exceeded the
user-selectable value for
acceptable link delay.
The link is removed from the
group.
Group [n] Abort Generated when Group [n]
Symmetry Config. Abort is generated,
due to group symmetry
problem
Group [n] Config The near end node rejects the
Abort far end IMA parameters.
ATM Forum (R-128)
Group [n] Degraded The IMA group is passing data
Service with less than the number of
IMA links you configured.
Group [n] Dup. IMA The same group IMA ID has
ID been received on links
belonging to different IMA
groups in the same card.
Group [n] FE Abort The far end rejects the
Symmetry symmetry sent by the near end.
Group [n] FE The far end reports it is not
Blocked passing data.
ATM Forum (R-132)
Group [n] FE Config The far end rejects the M value
Abort used by the near end.
Group [n] FE Start The far end is coming up
Up (starting IMA).
ATM Forum (R-127)
Group [n] FE The far end node is reporting
Insufficient Links an insufficient number of links.

Troubleshooting Steps
Check the links for proper connection.
Reconnect if necessary.
Check the links for proper connection.
Reconnect if necessary. Also try
adjusting the link delay parameter for
the IMA group.
Check and correct near end symmetry.
Only symmetric operation is supported
in PathBuilder switches.
Check and correct the near end and far
end parameters for compatibility.
Continue passing data. Correct faulty
links or adjust IMA group
configuration.
Correct link or group configuration.
Check and correct near end symmetry.
Only symmetric operation is supported
in PathBuilder switches.
Check and repair link facilities. Verify
configuration.
Configure both ends to the same M
value.
NOTE: This alarm should not occur if
both ends are PathBuilder S310, S330,
S600, or S700 switches.
Information about far end state.
Check and repair link facilities. Verify
configuration.
