210 Chapter 22 Configuring CLID on your system
Blocking outgoing name display at the trunks
To block outgoing name display at the media bay module level, you can configure module records
to disable the Send Name display check box, select Configuration > Resources > Telephony
Resources > Trunk Module Parameters (not available for all trunk types). Refer to
Module Parameters" on page
Guide (NN40020-300).
Blocking outgoing name display at the telephone
ONN is also enabled and disabled from a telephone, on a per-call basis, using FEATURE 819.
To allow FEATURE 819 to work correctly, you may need to specify an ONN blocking service
code.
The BCM alerts the CO by two methods. The method used depends on the type of trunk involved
in placing the outgoing call. This information is supplied by your service provider.
• Analog trunks use a dialing digit sequence called a Vertical Service Code (VSC). The VSC
differs from region to region and must be programmed. Analog trunks with both tone and
pulse dialing trunks can have separate VSCs.
• PRI trunks have only one VSC. No specific system programming is required.
ETSI note: ETSI lines may use the Calling Line Information Restriction (CLIR)
supplementary service to provide this feature.
ETSI PRI lines do not use a VSC. The line always uses Suppression bit to invoke the CLIR
supplementary service.
• BRI trunks can be set to either:
— provide ONN using a suppression bit, which provides a notice from the system to the
central office to withhold CLI.
— provide ONN using a VCS, which is dialed out in front of the dialed digits (optional on
ETSI trunks).
BRI trunk ONN settings are located under the loops settings. Refer to
T-loops" on page
Guide (NN40020-300).
Programming note: Ensure that users who have access to this feature have telephones with valid
OLI numbers.
