2、utions Approved June 2018 American National Standards Institute, Inc. Abstract This standard provides the specifications, characteristics, and values of the National Security/Emergency Preparedness (NS/EP) Telecommunications Service Priority (TSP) code. The TSP System is a Federal Communications Com

This standard contains clauses covering its purpose and scope, code representation, allowable code values, and relative importance of activities associated with services having NS/EP TSP de

ATIS-0300211.2018 ii Foreword The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accordance with ANSIs requirements for an ANS. As such, this Foreword may contain material that has not been subjected to public rev
5、iew or a consensus process. In addition, it does not contain requirements necessary for conformance to the Standard. The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between providers, customers, and manufacturers. The Telecom Management a

7、ated to U.S.A. communication networks in coordination with the development of international standards. ANSI guidelines specify two categories of requirements: mandatory and recommendation. The mandatory requirements are designated by the word shall and recommendations by the word should. Where both
8、a mandatory requirement and a recommendation are specified for the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. Suggestions for improvement of this document are welcome. They should be sent to the Alliance for

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
23、contain data elements that are defined and described in the following clauses. 5.1 Provisioning Priority Code A standard code to identify the type of priority level needed for the designated service. This data element shall consist of one alpha or one numeric character. 5.2 Restoration Priority (RP)
24、 Code A standard code to identify the type of priority level needed for restoration of the service users designated service. 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. AT
25、IS-0300211.2018 4 6.1 Provisioning Priority Code A standard code to designate the provisioning priority level for the designated request. This 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 6.1 depicts the
26、relationship of each code value among the choices available. Table 6.1 Provisioning Character Representation Relationships E Highest 1 2 3 4 5 Lowest 0 (ZERO) 6.2 Restoration Priority Code A standard code to designate the restoration priority level for the designated service. This data element shall
27、 consist of one character with the fixed values of 1, 2, 3, 4, 5, or 0 (zero). A zero indicates that no restoration priority is assigned. Table 6.2 depicts the relationship of each code value among the choices available. Table 6.2 Restoration Character Representation Relationships 1 Highest 2 3 4 5
28、Lowest 0 (ZERO) 6.3 Provisioning for example, DS3 or OC-3 circuits can be requested for designated NS/EP use. 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 availa
29、ble. A request for a physical circuit dedicated for NS/EP (e.g., private line) requires the use of TSP codes 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
30、a SONET ring), then TSP codes do not apply for the automated restoration process. If manual repair is necessary, 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
31、 (GETS) in the PSTN to a broader class of services in NGN/IP environments known as Emergency Telecommunications Service (ETS) requires enhancements for automated preferential treatment as described in ATIS-1000010, Support of Emergency Telecommunications Service (ETS) in IP Networks3. ETS comprises
32、real-time Voice over IP calls as well as other forms of telecommunications traffic data, video, 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 i
33、n the PSTN, TSP codes do not apply directly. Rather, as in the case for GETS service in the PSTN, 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 pr
34、eferred service over other services, signaling extensions are used to communicate the high priority of ETS, and finally priority-enabling mechanisms are defined that recognize the signaled priority and provide desired actions. Additional detail is provided in ATIS-1000023, ETS Network Element Requir
35、ements for a NGN IMS Based Deployments.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 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. 3This document is available from the Alliance for Telecommunications Industry Solutions (ATIS), at
