What is usrSS7SLAPSecondaryLinkDownCause?

This read-only value reports why the SLAP connection to the secondary SS7 gateway went down, using the same cause codes as the primary link (none, heartbeatExpired, socketError, physicalLinkCut, manualDisconect). An admin checks this when failover to the backup gateway also fails, to see why the secondary link itself is unavailable.
