| |
| = Functionality |
| |
| The BSSGP v13.0.0 protocol module implements the message structures of the related protocol <<_4, [4]>> 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. |
| |
| The BSSGP v13.0.0 protocol module uses Titan’s RAW encoding attributes <<_3, [3]>> and hence is usable with the Titan test toolset only. |
| |
| == Implemented Protocols |
| |
| This set of protocol modules implements protocol messages and constants of the BSSGP v13.0.0 protocol as described in <<_4, [4]>>. |
| |
| === Modified and Non-Implemented Protocol Elements |
| |
| None. |
| |
| == Backward Incompatibilities |
| |
| None. |
| |
| == 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 version CRL 113 200/5 R4A (5.4.pl0) or higher installed. For Installation Guide see <<_2, [2]>>. |
| |
| NOTE: This version of the test port is not compatible with Titan releases earlier than CRL 113 200/5 R4A. |
| |
| = Usage |
| |
| == 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 TTCN3enabled text editor is recommended (for example `nedit`, `xemacs`). Since the BSSGP v13.0.0 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 <<_2, [2]>>. |
| |
| == Configuration |
| |
| None. |
| |
| == Examples |
| |
| None. |
| |
| = Interface Description |
| |
| == Top Level PDU |
| |
| The top level PDU is the TTCN-3 union `PDU_BSSGP`. |
| |
| [[encoding-decoding-and-other-related-functions]] |
| == Encoding/Decoding and Other Related Functions |
| |
| This product also contains encoding/decoding functions, which assure correct encoding of messages when sent from Titan and correct decoding of messages when received by Titan. |
