1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-1000639.a.2001(R2011) Supplement to Calling Name Identification Restriction ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information,
2、 entertainment and communications industry. More than 250 companies actively formulate standards in ATIS 18 Committees, covering issues including: IPTV, Service Oriented Networks, Energy Efficiency, IP-Based and Wireless Technologies, Quality of Service, and Billing and Operational Support. In addit
3、ion, numerous Incubators, Focus and Exploratory Groups address emerging industry priorities including “Green”, IP Downloadable Security, Next Generation Carrier Interconnect, IPv6 and Convergence. ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a
4、member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications Sectors, and a member of the Inter-American Telecommunication Commission (CITEL). For more information, please visit . AMERICAN NATIONAL STANDARD Approval of an American National Standar
5、d requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materiall
6、y affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely volunt
7、ary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and
8、 will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addre
9、ssed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise

Notice of Disclaimer 1Refer to the Code of Federal Regulations, Title 47, Part 64, section 64.1601, which was modif
11、ied as a result of FCC Docket No. 91-281, “Rules and Policies Regarding Calling Number Identification Service - Caller ID“. 2This document is available from the Alliance for Telecommunications Industry Solutions, 1200 G Street N.W., Suite 500, Washington, DC 20005. ATIS-1000639.a.2001 2 b) Provide a
12、 single activation code that can be used by the caller to concurrently invoke both CLIR and CNIR; c) For calls originated on an ISDN access, apply the presentation indicator value that is received for the calling party number to both the calling party number and the calling name. 3. Add the followin
13、g subclause to clause 6.3.2.1 (Normal operation at the originating switch): 6.3.2.1.5 Signaling procedures for when CLIR and CNIR are linked When CLIR and CNIR are linked as described in 4.2.2.2.4, then the functional and stimulus signaling procedures of the CLIR supplementary service see T1.625-199
14、3 (R 1999) shall be applied to concurrently invoke both CLIR and CNIR. The presentation status of the calling name shall follow the presentation status of the calling party number, as follows: a) If the presentation status for CLIR is “presentation allowed“ then the presentation status for CNIR shal
15、l be set to “public.“ b) If the presentation status for CLIR is “presentation restricted“ then the presentation status for CNIR shall be set to “private.“ 4. Replace the middle paragraph of 6.3.3.1 with the following paragraph (Error handling for the functional signaling procedures): The network wil
16、l reject a request to “modify network stored value,” “force name status private,” or “force name status public” if the user has not subscribed to the corresponding Calling Name Identification Restriction service. When the network rejects a “modify network stored value” request, it initiates call cle
17、aring and sends a return error component with the userNotSubscribed error value. When the network rejects a “force name status private” or “force name status public” request it initiates call clearing with cause #50, “requested facility not subscribed.” 5. Add the following subclause to clause 6.3.3
18、 (Error handling): 6.3.3.3 Error handling for when CLIR and CNIR are linked When CLIR and CNIR are linked as described in 4.2.2.2.4, then the following error procedures apply: a) If a Facility information element with modifyNamePrivacyStatus or callingName operation is received by the network, a ret
19、urn error component with the proceduralError value shall be sent to the user in a FACILITY message. b) If a Feature activation information element coded as “feature identifier = force name status public“, or coded as “feature identifier = force name status private“, or coded as “feature identifier =
20、 modify network stored value“ is received by the network, the network shall reject the Feature activator request by sending a national specific cause value #53 “service operation violated“ with diagnostic “long term denial“ in an INFOrmation or STATUS message to the calling user. 6. Remove the following reference from Annex A (Bibliography): T1.625-1993, Telecommunications - Integrated services digital network (ISDN) - Calling line presentation and restriction supplementary services.
