SCOPE, PURPOSE, AND APPLICATION

tML Framework Document (ITU-T Recommendation M.3030) identifies potential applications for using XML in the interface design specification. Fault Management (Trouble Administration) 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 ANSI standards ATIS-0300227 and ATIS- 0300228. The formal analysis phase from M.3020 is not included in this document. This document presents the design phase using XML schemas (tML TA schemas) for Trouble Administration functions and services specified in ATIS-0300227/ATIS-0300228. The design phase is a result of analyzing (in the form of UML model) ATIS-0300227/ATIS-0300228data definitions. The model does not include enhanced features such as multiple object operations available based on the protocol design in ATIS- 0300227/ATIS-0300228. A Trouble Administration architecture diagram based on ATIS-0300227/ATIS- 0300228is shown in Figure 1 below.

The approach used in this standard defines XML application protocol data units that are specific to a subset of TA as defined in ATIS-0300227/ATIS-0300228 (ANSI version of ITU-T X.790). The XML messages specified in this standard are defined via an XML schema (tML-TA schema) and there is no coupling to a transport protocol. While mapping to a transport protocol (such as tML Transport Protocol, see Ref [15]) 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 the XML schemas (tML TA schemas) for trouble administration functions and services specified in ATIS-0300227/ATIS-0300228.
