Section 3.1 says:

"The MA may be pre-configured with an MA ID, or may use a Device ID in
   the first Controller contact before it is assigned an MA ID.  The
   Device ID may be a MAC address or some other device identifier
   expressed as a URI.  If the MA ID is not provided at this stage then
   it must be provided by the Controller during Configuration.”

Why would an MA be sending a status report before configuration?

Thanks,
