The gateway trunk links are down. A trunk cable of the controller may be disconnected. | Use the ALARMS maintenance command to get the list of alarms and their categories. Look for the Gateway Link alarm category, and verify the Unavailable percentage against the alarm threshold percentages to determine the alarm level.

You can use the SET THRESHOLDS GATEWAY TRUNKS maintenance command to change the alarm thresholds for the gateway link.
