| |
| == How to Read This Document |
| |
| This is the Function Specification for the set of SNDCP protocol modules. SNDCP protocol modules are developed for the TTCN-3 Toolset with TITAN. |
| |
| == Scope |
| |
| The purpose of this document is to specify the content of the SNDCP 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]>>. |
| |
| Protocol modules are using Titan’s RAW encoding attributes <<_4, [4]>> and hence is usable with the Titan test toolset only. |
| |
| = Functional Specification |
| |
| == Protocol Version Implemented |
| |
| This set of protocol modules implements protocol messages and constants of the SNDCP protocol - 3GPP TS 44.065 V7.0.0 (see <<_1, [1]>>). |

| |
| [[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: |
