| |
| == 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. |
| |
| [[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 that assure correct encoding of messages when sent from Titan and correct decoding of messages when received by Titan. Implemented encoding/decoding functions: |
