ISO/IEC 11579-3:1999 PDF

Overview

ISO/IEC 11579-3:1999 is an international standard developed by ISO and IEC that defines a reference configuration for extension lines within a private integrated services network exchange (PINX). This standard serves as Part 3 of the ISO/IEC 11579 series, focusing specifically on the extension line configurations for PINXs. It provides a framework for organizing high level functions in addition to the physical termination system described in Part 1, without mandating specific implementations. The guidance set out in this standard supports both ISDN-like and non-ISDN-like applications, enabling flexible and robust communication solutions in private integrated services networks (PISNs).

Key Topics

• Reference Configuration for Extension Lines

  • Specifies the layout of functional groupings for PINX extension lines.
  • Supports high level functions beyond the physical termination system.

• Principles for Functional Grouping and Reference Points

  • Describes how to combine different functional groupings within the extension line.
  • Establishes rules for allocating reference points without prescribing fixed configurations.
  • Provides examples of grouping combinations and reference point allocations to illustrate possible implementations.

• Transceivers and Control Functions

  • Details the use of transceiver (TCVR) groupings that manage signal reception, amplification, regeneration, and transmission.
  • Outlines the role of transceiver control functions (TCFs) and their connection via specified reference points.

• Support for Diverse Applications

  • Designed to accommodate a variety of application-dependent, high-level functions.
  • Sufficiently generic to enable both traditional ISDN and modern, non-ISDN applications.

Applications

ISO/IEC 11579-3:1999 provides practical value for organizations seeking to implement or enhance private integrated services network exchanges. Key use cases include:

• Private Telecommunications Networks

  • Facilitates the design and specification of flexible extension line infrastructures within enterprise or campus-wide telephony networks.
  • Supports integration with voice, data, and multimedia services.

• 2-Wire/4-Wire Conversion

  • Enables efficient cabling strategies by supporting cost-effective two-wire extensions and compatibility with four-wire ISDN interfaces.

• Wireless Mobility

  • Accommodates wireless mobility solutions by providing a reference configuration that integrates mobile and fixed radio equipment, supporting modern workplace mobility requirements.

• Campus and Backbone Cabling

  • Guides the implementation of extension lines over campus-wide area networks, including those leveraging ATM backbones and circuit emulation.

By adhering to this standard, network planners and implementers can achieve interoperable, scalable, and application-agnostic PISN extension lines, ensuring future-proof integration with evolving technologies.
