INTRODUCTION

tML Framework Document (ITU-T Recommendation M.3030) identifies potential applications for using XML in the interface design specification. POTS Service Test is one such application. ITU-T Recommendation M.3020 defines a three phase methodology for developing interface specifications related to management information exchanges The requirements phase has not been formally defined but is derived from existing standards: ITU-T Recommendation X.745 for the generic test management architecture and ATIS-0300262.2007 specific POTS service level tests including tone tests. The formal analysis phase from M.3020 is not included in this document. This document presents the design phase using XML schemas (tML POTS schemas) for POTS Service Test functions and services specified in ATIS-0300262.2007. The design phase is a result of analyzing (in the form of UML model) ATIS- 0300262.2007 data definitions. The general architecture for service level test is based on the "uncontrolled test" formalism in X.745. The test action performer is the agent in the managing system that performs the test based on the request from managing system.

The approach used in this standard defines XML application protocol data units that are specific to uncontrolled POTS service test as defined in ATIS-0300262.2007. The XML messages specified in this standard are defined via an XML schema (tML-ServiceTest schema) and there is no coupling to a transport protocol. While mapping to a transport protocol is required for interoperability, it is outside the scope of this document, and should be addressed by each pair of bonded companies as a joint implementation issue.

Purpose

The purpose of this document is to provide an XML schema interface (tML ServiceTest interface) for uncontrolled POTS Service Test function specified in ATIS-0300262.2007.
