ITU-T Recommendations

This is a revised version of the MTP Protocol Tester, published in March 1993 as Recommendation Q.755.The MTP Protocol Tester is used as an aid in testing between two implementations of the MTP of Signalling System No. 7. Its main use is as a tool for performing routing and bidirectionality tests for SS No. 7 in networks which are in service. In the international network, it would be the preferred message traffic generator. It is also a possible tool for validation testing when message traffic generation is needed whilst performing tests, and a possible message traffic generator for compatibility tests between different network operators. The tester is connected to the MTP as a user part, i.e. it is identified by a service indicator. It generates test traffic messages containing a serial number (and possibly additional information). On reception of these messages, the receiving tester checks that they have been delivered correctly (e.g. without loss, corruption, mis-sequencing or duplication).There is only one message traffic stream in any test; this means that the tester is not suitable for all tests of Recommendation Q.782.The tester would need extensions for message rate and length considerations for broadband MTP testing.
