+
+== How to Read This Document
+
+This is the Function Specification for the set of SUA protocol modules. SUA protocol modules are developed for the TTCN-3 Toolset with TITAN.
+
+== Scope
+
+The purpose of this document is to specify the content of the SUA protocol modules.
+
+= General
+
+Protocol modules implement the message structures of the related protocol in a formalized way, using the standard specification language TTCN-3. This allows definition of test data (templates) in TTCN-3 language <<_2, [2]>> and correct encoding/decoding of 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 the SUA protocol (see <<_1, [1]>>).
+
+[[modifications-deviations-related-to-the-protocol-specification]]

+
+=== Implemented Messages
+
+All SUA message types of message classes 0, 2, 3, 4, 7, 8 and 9 as listed in chapter 3.1.2 of <<_1, [1]>> will be implemented.

+
+== About This Document
+
+=== How to Read This Document
+
+This is the User Guide for the SUA protocol module. The SUA 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.
+
+SUA is specified in the Request for Comments 3868 <<_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.
+
+= Protocol Modules
+
+== Overview
+
+Protocol modules implement the message structures of the related protocol in a formalized way, using the standard specification language TTCN-3. This allows definition of test data (templates) in TTCN-3 language <<_1, [1]>> and correct encoding/decoding of messages when executing test suites using the Titan TTCN-3 test environment.
+
+Protocol modules are using Titan’s RAW encoding attributes <<_2, [2]>> and hence are usable with the Titan test toolset only.
+
+The table below contains the implemented messages and the corresponding TTCN-3 type records. Using those type records, templates can be defined to send and receive a given message.

+
+== Installation
+
+The set of protocol modules can be used for developing TTCN-3 test suites using any text editor. However to make the work more efficient a TTCN-3-enabled text editor is recommended (e.g. `nedit`, `xemacs`). Since the SUA 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
+
+None.
+
+= Example
+
+There are no examples available for this protocol module.
+
+= Terminology
+
+== Application Server Process (ASP)
+
+An Application Server Process serves as an active or backup process of an Application Server (e.g., part of a distributed signaling node or database element). Examples of Application Server Processes are MGCs, IP SCPs, or IP-based HLRs.
