+= M2UA Protocol Modules for TTCN-3 Toolset with TITAN, Function Specification
+:author: Gábor Szalai

+
+== How to Read This Document
+
+This is the Function Specification for the M2UA protocol module. M2UA protocol module is developed for the TTCN-3 Toolset with TITAN.
+
+== Scope
+
+The purpose of this document is to specify the content of the M2UA protocol module.
+
+= General
+
+Protocol modules implement the message structures of the related protocol in a formalized way, using the standard specification language TTCN-3. This allows defining of test data (templates) in the TTCN-3 language <<_2, [2]>> and correctly encoding/decoding messages when executing test suites using the Titan TTCN-3 test environment.
+
+Protocol modules are using Titan’s RAW encoding attributes <<_3, [3]>> and hence are usable with the Titan test toolset only.
+
+= Functional Specification
+
+== Protocol Version Implemented
+
+This set of protocol modules implements protocol messages and constants of M2UA protocol (see <<_1, [1]>>).
+
+[[modifications-deviations-related-to-the-protocol-specification]]
+== Modifications/deviations Related to the Protocol Specification
+
+=== Implemented Messages
+
+All M2UA message types of message classes 0, 3, 4, 6 and 10 as listed in chapter 3.1.4 of <<_1, [1]>> will be implemented.
+
+All M2UA parameters as listed in chapter 3.1.6 of <<_1, [1]>> will be implemented.
+
+[[protocol-modifications-deviations]]
+=== Protocol Modifications/Deviations
+
+Although the interface identifier parameters 0x0001, 0x0008 (integer) and 0x0003 (text) are mutually exclusive (see e.g. chapter 3.3.2.7 in <<_1, [1]>>), this restriction has not been implemented.
+
+[[encoding-decoding-and-other-related-functions]]
+== Encoding/Decoding and Other Related Functions
+
+This product also contains encoding/decoding functions that assure correct encoding of messages when sent from Titan and correct decoding of messages when received by Titan. Implemented encoding/decoding functions:
+
+[cols=3*,options=header]
+|===
+
+|Name
+|Type of formal parameters
+|Type of return value
+
+|`enc_PDU_M2UA`
+|PDU_M2UA
+|octetstring
+
+|`dec_PDU_M2UA`
+|octetstring
+|PDU_M2UA
+|===
+
+== Limitations
+
+Debug log generation is not supported when this revision of this product is used with TITAN version R7A (1.7pl0), because the encoder/decoder functions, automatically generated by TITAN version R7A (1.7pl0) does not contain logging functions. Newer versions of TITAN supports the debug logging within the automatically generated encoder/decoder functions that can be activated by allowing the `DEBUG_ENCDEC` (see <<_3, [3]>>, clause 7.2.3.2) in TITAN runtime configuration files.

+= M2UA Protocol Modules for TTCN-3 Toolset with TITAN, User Guide

+
+== About This Document
+
+=== How to Read This Document
+
+This is the User Guide for the M2UA protocol module. The M2UA protocol module is developed for the TTCN-3 Toolset with TITAN. This document should be read together with Function Specification <<_3, [3]>>.
+
+=== Presumed Knowledge
+
+To use this protocol module the knowledge of the TTCN-3 language <<_1, [1]>> is essential.
+
+M2UA is specified in the IETF RFC <<_4, [4]>>. A Function Specification was not available.
+
+== System Requirements
+
+Protocol modules are a set of TTCN-3 source code files that can be used as part of TTCN-3 test suites only. Hence, protocol modules alone do not put specific requirements on the system used. However in order to compile and execute a TTCN-3 test suite using the set of protocol modules the following system requirements must be satisfied:
+
+* TITAN TTCN-3 Test Executor R7A (1.7.pl0) or higher installed. For installation guide see <<_2, [2]>>.
+
+NOTE: This version of the protocol module is not compatible with TITAN releases earlier than R7A.
+

+
+== Installation
+
+The set of protocol modules can be used in developing TTCN-3 test suites using any text editor. Howeve,r to make the work more efficient a TTCN-3-enabled text editor is recommended (e.g. `nedit`, `xemacs`). Since the M2UA protocol is used as a part of a TTCN-3 test suite, this requires TTCN-3 Test Executor be installed before the module can be compiled and executed together with other parts of the test suite. For more details on the installation of TTCN-3 Test Executor see the relevant section of <<_2, [2]>>.
+
+== Configuration
+
