AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria fo

6、r 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 materially affected interests. Substantial agreement means much more than a simple majority, but not neces

7、sarily 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 voluntary; their existence does not in any respect preclude anyone, whether he has approved the standar

However, it is recommended that the code be represented with upper case letters. 5 Data Elements Clause 6 of this standard describes TSP code formats that contain data elements that are defined and described in the following clauses. 5.1 Provisioning Priority Code A standard code to identify the

26、type of priority level needed for the designated service. This data element shall consist of one alpha or one numeric character. ATIS-0300211.2012 4 5.2 Restoration Priority (RP) Code A standard code to identify the type of priority level needed for restoration of the service users designated servic

27、e. This data element shall consist of one numeric character. 6 Code Set Values This clause describes the TSP Code Set Values for each of the data elements defined in Clause 5. 6.1 Provisioning Priority Code A standard code to designate the provisioning priority level for the designated request. This

28、 data element shall have the fixed values of E, 1, 2, 3, 4, 5, or 0 (zero). A zero indicates that no provisioning priority is assigned. Table 1 depicts the relationship of each code value among the choices available. Table 1 - Provisioning Character Representation Relationships E Highest 1 2 3 4 5 L

This data element shall consist of one character with the fixed values of 1, 2, 3, 4, 5, or 0 (zero). A zero indicates that no restoration priority

30、 is assigned. Table 2 depicts the relationship of each code value among the choices available. Table 2 - Restoration Character Representation Relationships 1 Highest 2 3 4 5 Lowest 0 (ZERO) ATIS-0300211.2012 6 6.3 Provisioning for example, DS3 or OC-3 circuits can be requested for designated NS/EP u

31、se. Since TSP applies to physical circuits, direct TSP rules and codes apply for provisioning such circuits as well as in the case for manual repair if automated restoration means are not available. A request for a physical circuit dedicated for NS/EP (e.g., private line) requires the use of TSP cod

32、es for provisioning and manual repair per current practice. Once provisioned, if this circuit can be restored via automated capabilities under failure conditions (e.g., circuit provisioned over a SONET ring), then TSP codes do not apply for the automated restoration process. If manual repair is nece

33、ssary, then priority for repair is dictated by TSP codes per current practice. A.2 Emergency Telecommunications Service (ETS) The evolution of the Government Emergency Telecommunications Service (GETS) in the PSTN to a broader class of services in NGN/IP environments known as Emergency Telecommunica

34、tions Service (ETS) requires enhancements for automated preferential treatment as described in ATIS-1000010.2006 (R2011), Support of Emergency Telecommunications Service (ETS) in IP Networks2. ETS comprises real-time Voice over IP calls as well as other forms of telecommunications traffic data, vide

35、o, and multimedia. As in the case with GETS in the PSTN, whereby the Signaling System 7 (SS7) recognizes the initiation of a GETS call and provides preferential treatment over a non-GETS call for admission in the PSTN, TSP codes do not apply directly. Rather, as in the case for GETS service in the P

36、STN, priority rules and mechanisms are needed in NGN/IP environments in order to facilitate preferential admission and restoration policies. Specifically, priority agreements are used to classify ETS as a preferred service over other services, signaling extensions are used to communicate the high pr

37、iority of ETS, and finally priority-enabling mechanisms are defined that recognize the signaled priority and provide desired actions.3A request for an NS/EP service such as ETS that requires signaling procedures for call/session setup does not require the use of TSP codes. In such cases, the service

38、 request is established by signaling the “High” priority for call/session setup and service restoration in case of failure conditions. NS/EP services are classified with the highest available priority for admission control and service restoration. 2This document is available from the Alliance for Telecommunications Industry Solutions (ATIS), 1200 G Street N.W., Suite 500, Washington, DC 20005. 3Additional detail is provided in ATIS-1000023.2008, ETS Network Element Requirements for a NGN IMS Based Deployments, also available at the link in footnote 2.
