What is adsl2LInvSerialNumber?

This field (0 to 32 ASCII characters) uniquely identifies an individual ATU device with a manufacturer serial number, such as 'SN:ADSL2-2023001-B4A7'. An engineer uses the serial number for inventory management, warranty verification, RMA processing, and linking field data to a specific physical unit for troubleshooting. Example: an engineer queries serial numbers across a region to verify all units in service are under warranty and no counterfeit equipment is deployed.
