172 CHAPTER 5: PATHBUILDER S330 DIAGNOSTICS AND PERFORMANCE STATISTICS Table 28 DS1/E1 UNI Module Alarms (continued) Alarm Meaning Troubleshooting Steps BAD SCCI (3Com Patent Pending) Status and Change Control Indication - the content of the ICP cells has changed. The far end ICP cell SCCI in this link does not agree with the SCCI of the other links in the group. Check the links for proper connection. Reconnect if necessary. Bad Symmetry The far end group symmetry Remove the link and stop Tx and Rx has changed in an IMA link. data. Duplicated IMA ID An IMA group has received an IMA ID that has been received by a previous group. The second group must have a unique IMA ID. Check for loops and check the IMA group configuration. Duplicated Link ID Duplicated far end logical link ID in this IMA group for this IMA link. Check the links for proper connection. Reconnect if necessary. Each IMA group assigns a unique Transmit link ID to each link in the group. This link ID should match the Receive link ID of the remote end IMA device. This alarm means that a link received a Transmit link ID already assigned to a previous link. Duplicated Offset Duplicated far end ICP cell offset in this IMA group in an IMA link. Check the links for proper connection. Reconnect if necessary. 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. Check the links for proper connection. Reconnect if necessary. Also try adjusting the link delay parameter for the IMA group. Group [n] Abort Symmetry Generated when Group [n] Config.
