Broadband Integrated Services Digital Network (B-ISDN); Digital Subscriber Signalling System No. Two (DSS2) Protocol; Quality of Service Class and Parameters Indication at Call/Connection Establishment; Part 2: Protocol Implementation Conformance Statemen
"Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Services and Protocols for Advanced Networks (SPAN)@ and is now submitted for the Public Enquiry phase of the ETSI standards Two-step Approval Procedure. The present document is part 2 of a multi-part deliverable covering the Digital Subscriber Signalling System No. two (DSS2) protocol specification for the Broadband Integrated Services Digital Network (B-ISDN) to support Quality of Service Class and parameters indication at call/connection establishment@ as identified below: Part 1: ""Protocol specification [ITU-T Recommendations Q.2965.1 (1999) and Q.2965.2 (1999)@ modified]""; Part 2: ""Protocol Implementation Conformance Statement (PICS) proforma specification [Endorsement of ITU-T Recommendations Q.2965.1bis and Q.2965.2bis modified]"". Part 3: ""Test Suite Structure and Test Purposes (TSSTP) specification for the user""; Part 4: ""Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma specification for the user""; Part 5: ""Test Suite and Test Purposes (TSSTP) specification for the network""; Part 6: ""Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma specification for the network"". To evaluate conformance of a particular implementation@ it is necessary to have a statement of which capabilities and options have been implemented for a given protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS). The Protocol specification@ part 1 of the present document@ extends the basic call control procedures defined in EN 300 443-1 [7] by supporting the connection characteristics (Quality of Service class@ End-to-end transit delay) indication."
