Recovery:

  1. This measurement should have a value of zero. If the link or the link’s association is known to be under maintenance, then a non-zero value in this measurement is expected.
  2. Otherwise, the link status can be viewed from the GUI main menu under SS7/Sigtran>Maintenance>Links.
  3. Also look in the event history from the GUI main menu under Alarms & Events>View History for events related to this link or the link’s association.
  4. Contact My Oracle Support (MOS) for assistance if needed.
