Enter the value of the highest regional level employed by the PNP network. Use
the following table to find the relationship between the network level and the

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.

beginning of local extensions. The PBX identifier is added
first, before Level 1 or Level 2 codes. For example, in private
networks with a 7-digit numbering plan, the first 3 digits of the
private-network number are often considered the PBX
identifier.
