== 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 Titans 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
=== Protocol Modifications/Deviations
== 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:
|Type of formal parameters
|Type of return value
= Terminology
No specific terminology is used.
