ISDN Numbering — Public/ Unknown
Issue 5 October 2002 973555-233-506
PBX Identifier
NOTE:
The PBX identifier does not depend on the network level. Therefore, in a
level 0 private network you can use this field to create a level 0 number
longer than 5 digits.
ISDN Numbering — Public/ Unknown
This screen supports the ISDN Call Identification Display feature. The feature
provides a name/number display for display-equipped stations within an ISDN
network. The system uses the caller’s name and number and displays it on the
called party’s display. Likewise, the called party’s name and number can be
displayed on the caller’s display.
The screen allows you to specify the desired digits for the Calling Number IE and
the Connected Number IE (in addition to the QSIG Party Number) for any
extension in the Public and/or Unknown Number Plans.
Administer these screens if either the Send Calling Number, Send Connected
Number field is specified, or the Supplementary Service Protocol field is
b on the
trunk group screen.
NOTE:
If the table is not properly administered and the Send Calling Number or
Send Connected Number field is
y or r and the Numbering Format field on
the ISDN Trunk Group screen is
public or unknown, the Calling Number
and Connected Number IE are not sent. If the table is not administered, but
the Send Calling Number or Send Connected Number field is
public or
unknown, the Identification Number (PartyNumber data type) is not sent
for QSIG PartyNumbers. In this case, the ASN.1 data type containing the
PartyNumber (PresentedAddressScreened, PresentedAddressUnscreened,
PresentedNumberScreened, or PresentedNumberUnscreened) will be sent
marked as “PresentationRestricted” with “NULL” for the associated digits.

Enter up to 5 digits. Digits entered in this field are added to
the 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.
