In QSIG standards, this level 2 code is called the Level 1 Regional Code.

blank If this field is blank and the Send Calling Number and/or Send
Connected Number field is
y or r with private specified for
the Numbering Format field on the ISDN Trunk Group screen,
the Calling Number and/or Connected Number IEs will not be
sent.
If the field is left blank but
private has been specified in the
Numbering Format field on the ISDN Trunk Group screen, the
Identification Number (PartyNumber data type) is sent for
QSIG PartyNumbers encoded in ASN.1-defined APDUs. In
this case, the ASN.1 data type containing the PartyNumber
(PresentedAddressScreened, PresentedAddressUnscreened,
PresentedNumberScreened, or PresentedNumberUnscreened)
is sent marked as “PresentationRestricted” with “NULL” for
the associated digits.
