ITU-T Q.3056 PDF

This Recommendation defines requirements for high level signalling procedures intended for use in controlling probes used for remote testing of network parameters.

The signalling procedures described in this Recommendation propose secure storage of measurement results and authorized access for users to test results, with no possibility of third parties modifying the structure and content of measurement results.

These procedures enable a probe to function as a "black box" recording all events on the subscriber side, and suitable for a trusted system in resolving disputes between various ICT stakeholders.
