This holds the Logical ONU ID value used when the selected confirm type is one of the LOID-based variants, an alternate identifier to serial number used in some GPON deployments (particularly those provisioning by logical account rather than hardware SN) to match a discovered unit to a subscriber record. An admin uses this scheme when the deployment's provisioning workflow is built around LOIDs issued to accounts rather than SNs printed on hardware. For example, a subscriber's assigned LOID entered here lets any physical ONU carrying that LOID be confirmed, regardless of which specific hardware SN it has.
