This Counter32, keyed by the ATM link index, counts OAM cells that were misinserted — OAM cells detected on a VP/VC that don't actually belong to that connection's expected OAM flow — with the source DESCRIPTION left blank so the meaning follows the standard ATM OAM cell misinsertion concept implied by the object name. Admins use this counter as a sanity check on the integrity of the OAM monitoring itself, since misinserted OAM cells can produce false continuity or alarm indications if not filtered correctly. For example, a rising count here alongside spurious AIS/RDI alarms on a VC would lead an admin to suspect OAM cell misinsertion rather than a genuine path fault.
