Overview

ISO/IEC 11584:1996 specifies the service description, functional capabilities and information flows for circuit-mode multi-rate bearer services in a Private Integrated Services Network (PISN). Built on ISDN concepts from ITU‑T and within the OSI framework, this International Standard defines Stage 1 (service description) and Stage 2 (functional capabilities & information flows) for nx64 kbit/s point-to-point, unrestricted digital bearer services. It complements public ISDN bearer specifications and guides Stage 3 signalling protocol development.

Key topics and technical requirements

• Service scope: Circuit-mode multi-rate unrestricted 8 kHz structured bearer service - supporting integer multiples of 64 kbit/s (e.g., 128, 192 … up to 1 920 kbit/s) for symmetric, bidirectional, point-to-point calls.
• Service attributes:
  • Dominant attributes: circuit mode, multiples of 64 kbit/s, unrestricted digital information, time-slot sequence integrity.
  • Secondary attributes: demand establishment, bidirectional symmetry, point-to-point configuration.
  • Access attributes: two or more B‑channels; access protocol not defined (signalling out of scope).
• Procedures: Call establishment (originating and terminating user procedures), continuous simultaneous two‑way transmission for call duration, call release and failure handling (user, called‑user, and network errors).
• Interworking: Requirements for interworking with ISDN and non‑ISDN networks; mapping non‑contiguous channels to contiguous channels may be required. Specific interworking examples include 2×64 kbit/s (128 kbit/s), 384 kbit/s, 1 536 kbit/s and 1 920 kbit/s bearer services.
• Limitations / Out of scope: Negotiation at call setup, channel aggregation interworking (Nx64 channel negotiation), and mid‑call service changes are excluded; charging mechanisms are outside the standard’s scope.
• Stages: Provides Stage 1 (service model) and Stage 2 (functional capabilities/information flows) to constrain Stage 3 signalling standards.

Applications and who uses this standard

• Telecom equipment vendors implementing PISN switches, PBX and private network interfaces.
• Network architects and engineers designing multi‑rate digital circuits inside enterprise networks.
• Standards and protocol developers creating Stage 3 signalling that must conform to Stage 1/2 service definitions.
• Integrators and operators ensuring interworking between private ISDN-like networks and public ISDN or legacy networks. Practical uses include private voice/data trunks, high‑capacity point‑to‑point links within enterprises, and controlled multi‑channel digital services where time‑slot integrity and fixed-rate circuit behaviour are required.

Related standards

• ISO/IEC 11574 - Circuit-mode 64 kbit/s bearer services (complements ISO/IEC 11584)
• ISO/IEC 11579‑1 - PISN reference configuration (PINX)

Foreword
IS0 (the International Organization for Standardization) and IEC (the Inter-
national Electrotechnical Commission) form the specialized system for
worldwide standardization. National bodies that are members of IS0 or
IEC participate in the development of International Standards through
technical committees established by the respective organization to deal
with particular fields of technical activity. IS0 and IEC technical com-
mittees collaborate in fields of mutual interest. Other international organ-
izations, governmental and non-governmental, in liaison with IS0 and IEC,
also take part in the work.
In the field of information technology, IS0 and IEC have established a joint
technical committee, lSO/IEC JTC 1. Draft International Standards adopted
by the joint technical committee are circulated to national bodies for vot-
ing. Publication as an International Standard requires approval by at least
75 % of the national bodies casting a vote.
International Standard lSO/lEC 11584 was prepared by Joint Technical
Committee lSO/IEC JTC 1, Information technology, Subcommittee SC 6,
Telecommunications and information exchange between systems.

Introduction
This International Standard is one of a series of IS0 standards describing the service specification functional
model and information flows applicable to Private Integrated Services Network. The series uses the ISDN
concepts as developed by ITU-T (formerly CCITT) and is also within the framework of standards for Open
Systems Interconnection as defined by ISO.
This particular International Standard defines the service specification for circuit mode multi-rate bearer
service.
The circuit-mode multi-rate bearer services for Private Integrated Services Network (PISN), specified in this
International Standard complement, and are compatible with the corresponding services for public ISDN as
specified by ITU-T (formerly CCITT). Specifications of the equivalent services are to be found in Rec. 1.220,
1.230, 1.231.
This International Standard contains the stage 1 and stage 2 specifications of the circuit-mode multi-rate
bearer sewices.

Section 1: General
1 Scope
This International Standard specifies service description and control aspects of the multi-rate circuit-mode
basic services which may be supported by Private Integrated Services Network (PISN).
One of the purposes of the stage 1 and stage 2 specifications is to guide and constrain the work on signalling
protocols at stage 3. Therefore, this International Standard is concerned mainly with the control aspects of
services.
A stage 3 standard shall be in conformance with this International Standard, if the signalling protocols and
equipment behavior specified in the stage 3 standard are capable of being used in a PISN which supports
any or all of the basic services specified in this International Standard.
This International Standard encompasses Circuit-Mode Multi-rate Unrestricted 8 kHz Structured Bearer
Service.
Negotiation of services at call establishment time, interworking using channel aggregation (Nx64kbWs) and
change of service during a call are outside the scope of this International Standard.
Conformance
In order to conform to this International Standard, a stage 3 standard shall specify signalling protocols and
equipment behavior that are capable of being used in a PISN which supports the bearer service specified in
this International Standard. This means that to claim conformance a Stage 3 standard is required to be
adequate for the support of those aspects of stage 1 (section 2) and stage 2 (section 3) which are relevant to
the interface or equipment to which the Stage 3 standard applies.

Section 2: Service Description, Stage 1
5 Circuit-mode multi-rate unrestricted 8 kHz structured bearer service
51 . Descriptions
The circuit-mode multi-rate bearer service allows PISN users to request on a demand basis unrestricted
information transfer rates at integer multiples of 64 kbit/s without alteration between PISN users.
This bearer service extends the circuit-mode bearer service based on 64 kbit/s by supporting higher
information transfer rates.
This circuit-mode bearer service allows two PISN users to communicate in a point-to-point configuration via
the PISN using nx64 kbit/s digital signals, in both directions continuously and simultaneously for the duration
of a call.
