This object reports how long this specific association has continuously been in the established state. This is the number that shows how stable one particular signaling link has been: an association whose uptime keeps resetting to a low value is repeatedly flapping, which is a very different situation from one peer's association that has stayed rock solid for weeks. An uptime of only 45 seconds on an association that should be permanent, such as one to a core MGC, points to rapid repeated reconnects rather than a single one-off outage.
