ISO IEC 11579-2:1999 pdf download – lnformation technology – Telecommunications and informationexchange between systems- Privateintegrated services network — Part 2: Reference configuration for HS-PISN Exchanges (HS-PINX).
This part of ISO/IEC 11579 specifies a reference configuration (RC) for high-speed private integrated services network exchanges (HS-PINX), for their interconnection to form high-speed private integrated services networks (HS-PISN). The configuration is intended to provide guidance for the specification of PINX capabilities, but does not impose any specific implementation of a HS-PINX.
This RC describes a conceptual HSPlNX By combining multiple HS•PINXs to a high-speed private integrated services network the RC becomes applicable to a HS-PISN. This is generically described in ISO/IEC 11579-1.
This RC satisfies the support of all HS applications, such as LAN. MAN, B-ISDN. etc.

For clarity some simplifications have been applied to Figure A.1:
-where necessary it shows multiple instances of functional groupings;
-statements related to the T, to the Qand to the C reference points have been omitted.
A TE as specified genericly in part 1 of lSO/IEC 11579 can be served by the narrow-band as well as by a broad-band subset of the swW functional grouping.
A TE offering HS capabilities (i.e.using PINX bearer capabilties of s64 kbi/s) can be served by the HS-swfunctional grouping, but can as well be served by n*64 kbit’s services.
This universal connectivity of N-TEs and HS-TEs to N-SWs and B-sWs relies on a versatile PTS concept thatallows the PTS to perform the corresponding adaptation functions between N-TEs and HS-SWs and vice versa.
Also a LAN-IWU (so called LAN bridge) is considered a specific case of a PTS(not shown in Figure A.1). ltsimplementation depends on the specific conversion requirements between the bearer capatbilities used by the TEsand the SWs.
