24、alled party. The terminating network may receive the Calling Number Identification (CNI) as part of basic call setup. This CNI may include one or two Calling Party Numbers (CPNs), a Calling Party Subaddress (CPS), Redirecting Numbers (RNs), and Redirecting Subaddresses (RSs). Subaddress information
25、is information other than the CPNs and Redirecting Number (RN) that identifies a particular party in a call. CNIR does not impact a subscribers ability to originate calls or to receive calls. Applicability to Telecommunications Services CNIR is applicable to voice telecommunications services. 1.1 No
26、rmal Procedure with Successful Outcome Authorization CNIR may be generally available or may be provided after prearrangement with the service provider. As a service provider option, CNIR may be offered with several subscription options. It is a service provider option as to how subscription options
27、are applied (e.g., per Directory Number and Bearer Service). The following table summarizes the subscription options: Table 1: CNIR Subscription Options Subscription Options Values CNIR Mode Not Subscribed. CNIR is inactive for all calls. Permanently Restricted. CNIR is active for all calls. Tempora
28、ry. The subscriber is authorized to control the activation and deactivation of CNIR on a per call basis.

Registration CNIR has no registration. Deregistration CNIR has no deregistration.
30、 Activation If subscribed to the Permanently Restricted CNIR Mode, CNIR is activated upon authorization. If subscribed to Temporary CNIR Mode with a Presentation Restricted Default, CNIR is activated upon authorization. Temporary Activation With a Call Setup Request (Per Call Blocking) CNIR may be a
31、ctivated concurrently with a particular call setup, as in: *FC + # + termination address + SEND . Alternatively: *FC + termination address + SEND is possible, if a fixed length temporary activation feature code is distinct from the deactivation feature code(s). If the temporary activation is accepte
32、d, the system may indicate success with feature confirmation treatment and the call is allowed to proceed. At the release of the call, CNIR shall resume the default state. Deactivation CNIR shall be deactivated upon deauthorization. If subscribed to Temporary CNIR Mode with a Presentation Allowed De
33、fault, CNIR is deactivated upon authorization. Temporary Deactivation with a Call Setup Request (Per Call Allow) CNIR may be deactivated concurrently with a particular call setup, as in: *FC0 + # + termination address + SEND .

35、he activation feature code(s). If the temporary deactivation is accepted, the system may indicate success with feature confirmation treatment and the call is allowed to proceed. At the completion of the call, CNIR shall resume the default state. Invocation CNIR is invoked for any calls originated by
36、 a subscriber or redirected on behalf of a subscriber and that subscriber has CNIR active. Normal Operation with Successful Outcome When the CNIR service is invoked, the originating network provides the destination network with a notification that the CNI is not allowed to be presented to the called
37、 party. The destination network should indicate presentation restricted to the called party who has subscribed to the CNIP service. In this situation the CNI is not presented to the called party or to the called party station. When a call is forwarded or redirected for a subscriber with CNIR active,
38、 the CNI that applies to that subscriber shall indicate presentation restricted. This CNI may include CPNs, a CPS, RNs and RSs. The original CNI, if included with the redirected call, shall include its original restrictions unaltered. The CNI may be stored by the terminating network for other featur
39、es or services. The stored CNI shall preserve the presentation restriction indications. A stored CNI that indicates restricted presentation shall not be presented to the called party or to the called party station. Call Detail Record The system should record call detail information for the following
40、: a. CNIR activation activities and events. b. CNIR deactivation activities and events. c. Originating and redirecting call records should indicate if CNIR was used. See DMH for the specific information to be included for each element. Numbers indicating presentation restricted should not be present

Activation Temporary Activation with a Call Setup Request (Per Call Blocking) If the subscriber is not authorized for a request made concurrently with a call setup request, the system shall apply feature deni
43、al treatment and the call setup shall be denied. If a subscriber with Presentation Restricted Default active attempts to activate the CNIR feature on a per call basis, the request shall be ignored (i.e., the system shall indicate that the calling number identification is presentation restricted) and
44、 the call setup shall be made as if the CNIR request had not been attempted. Deactivation Temporary Deactivation with a Call Setup Request (Per Call Allow) If the subscriber is not authorized for a request made concurrently with a call setup request, the system shall apply feature denial treatment a

If a subscriber with Presentation Allowed Default active attempts to deactivate the CNIR feature on a per call basis, the request shall be ignored (i.e., the system shall indicate that the calling number identification is presentation allowed) and the call setup sh
46、all be made as if the CNIR override request had not been attempted. Invocation None identified. Exceptions While Roaming Serving systems may elect to provide CNIR to all roamers by default.
