+= BSSAPP (V7.3.0) Protocol Modules for TTCN-3 Toolset with TITAN, Function Specification
+:author: János Kövesdi
+:revnumber: 155 17-CNL 113 580, Rev. A
+:revdate: 2013-09-05
+:toc:
+
+== How to Read This Document
+
+This is the Function Specification for the set of BSSAPP protocol modules. BSSAPP protocol modules are developed for the TTCN-3 Toolset with TITAN.
+
+== Scope
+
+The purpose of this document is to specify the content of the BSSAPP protocol modules. Basic knowledge of TTCN-3 <<_2, [2]>> and TITAN TTCN-3 Test Executor <<_3, [3]>> is valuable when reading this document.
+
+= 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 <<_3, [3]>>.
+
+The protocol modules are using Titan’s RAW encoding attributes <<_4, [4]>> and hence they 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 BSSAPP protocol. The modules are based on 29.018 V7.3.0 (see <<_1, [1]>>).
+
+=== Unimplemented Messages, Information Elements and Constants
+
+None.
+
+[[protocol-modifications-deviations]]
+=== Protocol Modifications/Deviations
+
+None.
+
+[[encoding-decoding-and-other-related-functions]]
+== Encoding/Decoding and Other Related Functions
+
+This product also contains encoding/decoding functions, which assure correct RAW encoding of messages when sent from Titan and correct RAW decoding of messages when received by Titan. Implemented encoding/decoding functions:

+
+== 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.
