Scope
This International Standard specifies the functional protocol for the support of supplementary services and additional basic callcapabilities at the Q-reference point. The Q-reference point exists between Private Integrated services Network eXchanges(PINX) connected together within a Private lIntegrated Services Network (PISN) and is defined in ISO/IEC 11579-1.Thegeneric functional protocol is part of the B-QSIG signalling system.
The procedures specified in this International Standard can be used in association with a bearer connection (bearer-related) oroutside the context of any bearer connection (bearer-independent).The application of this International Standard to individualadditional basic call capabilities and supplementary services is outside the scope of this International Standard and should bedefined in those standards or proprietary specifications that specify the individual capabilities.
All conformance to this International Standard is based on the external behaviour at the interface at the Q-reference point,i.e.on the generation of the correct message structure and in the proper sequence as specified in this International Standard.
The generic functional protocol is based on ATM Forum specification AF-CS-0102.000,which itself is based on the DSS2generic functional protocol specified in ITU-T Rec.Q.2932.1 but extended to allow non-local information exchange as well aslocal information exchange.
This International Standard is applicable to PINXs supporting additional basic call capabilities and/or supplementary servicesrequiring the functional protocol for signalling at the Q-reference point.
2Conformance
ln order to conform to this International Standard, a PINX shall satisfy the requirements identified in the ProtocolImplementation Conformance Statement (PICS) proforma in section 30 of AF-CS-o102.000.

4Terms and definitions
For the purposes of this International Standard, the terms and definitions given in section 26.3 of AF-CS-0102.000 and thefollowing apply.
4.1 Gateway PINX :The definition in ISOIEC 13247 shall apply. Dependent on the capabilities of the signalling systembeing interworked by the gateway PINX, it can act as a Transit or an End PINX in the context of the supplementary servicesAPDUs. That is, it can either transport the APDUs unchanged to or from the other signalling system, perhaps embedded insome other protocol unit, or process the APDUs and perform an interworking function of the information flows and encodingof the Supplementary service concerned.
4.2 Inter-PINX link (IPL) : The definition in ISO/IEC 13247 shall apply.
4.3 Preceding side : ln the context of a callconnection or a CO-Bl connection using an IPL, the side that initiatescallconnection or CO-BI connection establishment over that IPL (see figure 1 in ISO/IEC 13247).
4.4 Private Integrated services Network eXchange(PINX) : As specified in ISO/IEC 11579-1.
4.5 Succeeding side : In the context of a callconnection or a CO-BI connection using an lPL, the opposite side from the sidethat initiates call/connection or CO-Bl connection establishment over that IPL(see figure 1 in ISO/EC 13247).
NOTE – The term ‘node’in AF-CS-0102.000 is equal to the term ‘PINX’.
The term ‘PNNI* in AF-CS-0102.000 is equal to the term ‘B-QSIG .
