Digital subscriber signalling system No. 2 ? Support of Quality of Service classes: Protocol Implementation Conformance Statement (PICS) proforma (Study Group 11)
"This Recommendation specifies the Protocol Implementation Conformance Statement (PICS) proforma for the TB reference point or coincident SB and TB reference point (as defined in ITU-T I.413 [4]) of implementations conforming to the procedures for the handling of Quality of Service classes 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.2965.1 [1]. This Recommendation is applicable to equipment supporting B-ISDN calls/connections@ 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. 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 an Implementation Conformance Statement (ICS). An ICS stating what capabilities and options have been implemented for a particular protocol is called a protocol ICS. This is commonly abbreviated to ""PICS"". The supplier of a protocol implementation that is claimed to conform to ITU-T Q.2965.1 is required to complete a copy of the PICS proforma provided in Annex A. NOTE ? No PICS proforma is required to be completed for implementation capabilities not covered by this Recommendation. For coverage of capabilities@ refer to clause 6."
