Description: ONU serial number.
What is onuSerialNum?
This is the ONU's factory-assigned 8-octet serial number, the identifier the OLT uses to recognize and authenticate a specific physical device on the PON. Admins use it as the primary key when provisioning or looking up an ONU, since it's globally unique and printed on the device label. For example, a technician reads the serial number off the ONU's label and enters it here to bind a new device into the system.
