scope:

The present document specifies interoperability testing between nodes meeting the requirements of ITU-T Recommendations Q.711 to Q.714 [2] as modified by ETS 300 009-1 [1]. The present document may optionally also be applied within national networks and implementations of earlier versions of ETS 300 009 and the ITU-T Recommendations. The present document is not meant to restrict national networks. The tests in the present document form a basic set of interoperability tests, and are used in gaining confidence that implementations of the Signalling Connection Control Part (SCCP) can interwork.
