This read-only INTEGER is defined to report the number of connection IDs used for VCC connections on the trunk, though the object's own description explicitly notes it is 'not used' in this implementation. An administrator should therefore not rely on this value as an accurate real-time VCC resource count, since the underlying platform isn't populating it, and should instead check actual connection tables or parTrkCnfgVccConids for capacity planning. For example, an operator troubleshooting VCC exhaustion on a trunk would need to count entries in the connection table directly rather than trusting a static or stale reading here.
