scope:

This Interim European Telecommunication Standard (I-ETS) is part 3 of a three part I-ETS dealing with conformance testing of Integrated Services Digital Network (ISDN) Videotelephony terminals. Part 1 contains the Test Suite Structure and Test Purposes (TSS& TP) while part 2 contains the Abstract Test Suite (ATS) in Tree and Tabular Combined Notation (TTCN) and the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma. Part 3 provides the Protocol Implementation Conformance Statement (PICS) proforma for the inband signalling aspects of an ISDN Videotelephony terminal which uses one or two B channels, and which implements the frame structure and associated syntax as specified in ETS 300 144 [2] and the inband signalling procedures as specified in ETS 300 143 [1], in accordance with the relevant guidance given in ISO/IEC 9646-7 [6].
