适用范围
This second part of ETS 300 666 is applicable to the stage three of the Connected Line Identification Restriction (COLR) supplementary service for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as provided by European public telecommunications operators at the TB reference point or coincident SB and TB reference point (as defined in ITU-T Recommendation I.413 [9]) by means of the Digital Subscriber Signalling System No. two (DSS2). Stage three identifies the protocol procedures and switching functions needed to support a telecommunication service (see CCITT Recommendation I.130 [8]). This ETS provides the Protocol Implementation Conformance Statement (PICS) proforma for the B-ISDN DSS2 COLR supplementary service protocol as specified in ETS 300 666-1 [3] in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [7]. The supplier of a protocol implementation which is claimed to conform to ETS 300 666-1 [3] is required to complete a copy of the PICS proforma provided in annex A of this ETS and is required to provide the information necessary to identify both the supplier and the implementation.
