Overview
ISO/IEC 11579-2:1999 defines a reference configuration (RC) for High-Speed Private Integrated Services Network (HS-PISN) exchanges, known as HS-PINX. This international standard provides a conceptual framework for designing and interconnecting HS-PISN exchanges to form high-speed private integrated services networks. Its primary goal is to guide the specification of HS-PINX capabilities without mandating specific implementations.
The reference configuration supports a variety of high-speed applications, such as Local Area Networks (LAN), Metropolitan Area Networks (MAN), and Broadband Integrated Services Digital Networks (B-ISDN). By combining multiple HS-PINX devices, organizations can achieve robust, scalable, and flexible high-speed private networks designed to handle advanced telecommunications and information exchanges at rates exceeding 64 kbit/s.
Key Topics
-
High-Speed Private Integrated Services Network Exchanges (HS-PINX)
A conceptual model for HS-PINX is outlined that supports advanced switching and transmission technologies suited for high-speed data transfer.
-
Reference Points and Functional Groupings
The standard defines functional groupings within HS-PINX systems and reference points that facilitate interworking, management, and operation. This modular approach helps clarify responsibilities, performance partitioning, and protocol termination.
-
Interconnection Principles
HS-PINXs may interconnect through various intervening networks (IVN), ranging from physical wired connections to more complex switching networks such as public B-ISDN, allowing overlay configurations.
-
Support for Diverse Technologies
The reference configuration supports various bearer capabilities beyond 64 kbit/s, including ATM-based broadband services, LAN, MAN, and B-ISDN protocols, providing a versatile platform for private integrated services.
-
Adaptation and Conversion Functions
The standard introduces the concept of Private Termination Systems (PTS) and InterWorking Units (IWU), such as LAN-IWU, which perform conversion and adaptation between narrowband and broadband equipment or protocols, ensuring seamless communication across heterogeneous networks.
Applications
ISO/IEC 11579-2:1999's reference configuration is vital for organizations and network operators who need to:
- Design and implement high-speed private integrated services networks for corporate, campus, or metropolitan areas requiring secure, scalable internal communications.
- Integrate multiple HS-PINX systems into cohesive networks capable of supporting diverse applications, including multimedia, data, and voice services.
- Facilitate high-speed telecommunications infrastructure upgrades that can accommodate future technologies like B-ISDN and ATM.
- Ensure interoperability and management consistency within high-speed network exchanges, critical for maintenance and operation in complex environments.
- Enable overlay networking scenarios, where HS-PISNs operate in conjunction with public broadband networks, promoting hybrid infrastructure deployments.
By adhering to this standard, network designers can achieve efficient, reliable high-speed data exchange while minimizing deployment risks associated with incompatible implementations.
