== About This Document

=== How to Read This Document

This is the User Guide for the BSSAPP protocol module. The BSSAPP 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]>> and TITAN Test Executor <<_2, ‎[2]>> is essential.


== 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 ‎<<_5, [5]>>.

NOTE: This version of the protocol module is not compatible with TITAN releases earlier than R7A.

= Protocol Modules

== Overview

Protocol modules implement the messages structure 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 <<_1, ‎[1]>> and correctly encoding/decoding messages when executing test suites using the Titan TTCN-3 test environment ‎<<_2, [2]>>.

Protocol modules are using Titan’s RAW encoding attributes <<_4, ‎[4]>> and hence are usable with the Titan test toolset only.

== Installation

The set of protocol modules can be used in developing TTCN-3 test suites using any text editor. However to make the work more efficient a TTCN-3-enabled text editor is recommended (for example, nedit, xemacs). Since the BSSAPP 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 ‎<<_5, [5]>>.

== Configuration

None.

= Terminology

No specific terminology is used.
