| |
| == How to read This Document |
| |
| This is the Function Specification for the set of M2PA protocol modules. M2PA protocol modules are developed for the TTCN-3 Toolset with TITAN. |
| |
| == Scope |
| |
| The purpose of this document is to specify the content of the M2PA 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 defining of test data (templates) in the TTCN-3 language and correctly encoding/decoding messages when executing test suites using the TITAN TTCN-3 test environment. |
| |
| Protocol modules are using TITAN`s RAW encoding attributes <<_1, [1]>> and hence are usable with TITAN test toolset only. |
| |
| = Functional Specification |
| |
| == Protocol Version Implemented |
| |
| This protocol module contains the protocol messages and elements of the M2PA protocol <<_3, [3]>>. |

| == Modifications/Deviations Related to the Protocol Specifications |
| |
| === Implemented Messages |
| |
| All message types listed in protocol description <<_3, [3]>> are implemented. |
| |
| [[protocol-modifications-deviations]] |
| === Protocol Modifications/Deviations |
| |
| None. |
| |
| == Encoding Decoding and Other Related Functions |
| |
| This product contains encoding/decoding functions that provide for the correct encoding of messages when sent from TITAN, and correct decoding of messages when received by TITAN. For encoding and decoding the message two functions are available. |
| |
| * Function `enc_PDU_M2PA` makes simple RAW encoding without any modification on the input M2PA message. |
| * Function `dec_PDU_M2PA` makes simple RAW decoding without any modification on the input octetstring. |
