Operating parameters
ISDN QSIG Name Display Enhancement
• Calling/Connected Name Identification Restriction (CNIR). This
service prevents the name display of a calling party from being presented
to the called party.
CNIR may be activated for all calls by setting the CLS prompt in LD 10
or LD 11 to Name Presentation Denied (NAMD). If the CLS has been set
to Name Presentation Allowed (NAMA), CNIR may be activated on a
per-call basis, by dialing the Calling Party Privacy Flexible Code before
making a call.
Note: The capability of activating CNIR on ISDN BRI sets is not
supported.
These Name Display supplementary services are provided across an ISDN
QSIG network using the QSIG Generic Functional (GF) protocol transport
platform.
The QSIG Supplementary Service - Name Display Enhancement feature,
provides the option of choosing the method of Operation Coding for the
Name Display supplementary services described above. The choice may be
by Object Identifier, used for European Telecommunications Standard
Institute (ETSI) interfaces, or by Integer Value, used for International
Standards Organization (ISO) interfaces. The Operation Coding method is
configured as a remote capability using the RCAP prompt for an ISDN PRI
D-Channel for ISDN PRI, or for an ISDN BRI route for ISDN BRI trunking.
QSIG allows a maximum of 50 characters to be displayed for Name Display
information. However, up to only 27 characters are allowed with the Calling
Party Name Display feature. Consequently, if the name display string exceeds
27 characters, it will be truncated.
The QSIG Supplementary Service - Name Display Enhancement feature may
interwork with the MCDN Name Display feature, depending on the Network
Name Display (ND) method (either ND1, ND2, or ND3) configured as the
Remote Capability (using RCAP prompt in LD 17) for the associated
D-Channel. ND3 ensured the same level of service between the MCDN Name
Display and QSIG Name Display supplementary services.
The user-based service profile cannot be used to override the Calling Name
Identification Restriction service.
