Digital subscriber signalling system No. 2 (DSS2) – Additional traffic parameters: Abstract test suite (ATS) and partial protocol implementation extra information for testing (PIXIT) proforma for the user (Study Group 11)
This Recommendation specifies Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the user attached to the TB reference point or coincident SB and TB reference point (as defined in ITU-T I.413 [9]) of implementations conforming to the procedures for the handling of additional traffic parameters that may be used for basic call and connection control of the Digital Subscriber Signalling System No. 2 (DSS2) protocol for the Broadband Integrated Services Digital Network (B-ISDN)@ ITU-T Q.2961 [1]@ [2]@ [3]@ [4]@ [5] and [6]. Other Recommendations of the Q.2961 family specify the Protocol Implementation Conformance Statement (PICS) proforma and Test Suite Structure and Test Purposes (TSS TP) based on this Recommendation. This Recommendation is applicable to equipment@ supporting capabilities for the indication of traffic parameters above of the peak cell rate at connection request time@ to be attached at either side of a TB reference point or coincident SB and TB reference point when used as an access to the public B-ISDN. The ATS realizes test purposes identified in the TSS TP part of the Recommendation and groups them according to the test suite structure given in the TSS TP. Test purposes defined in the TSS TP part but not testable are identified in this Recommendation. The supplier of a protocol implementation that is claimed to conform to capabilities defined in a Q.2961-series Recommendation is required to complete a copy of the PICS proforma and the PIXIT proforma provided by the testlab. The PIXIT proforma shall contain the tables identified in the partial PIXIT proforma part of this Recommendation and may contain additional information required by the testlab to be able to appropriately execute the test campaign. NOTE ?C No conformance test service can be provided and therefore no PICS and PIXIT proforma is required to be completed for implementation capabilities not covered by this Recommendation. For coverage of capabilities refer to clause 4.
