Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Circuit-mode 64 kbit/s bearer services — Service description, functional capabilities and information flows
This International Standard specifies the service description and control aspects, including functional capabilities and information flows, of standardised circuit-mode bearer services which may be supported by a Private Integrated Services Network (PISN). This International Standard includes the following basic services: _ Circuit-mode 64 kbit/s unrestricted 8 kHz structured bearer service category; _ Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for speech information transfer; _ Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for 3,1 kHz audio information transfer. A PISN shall support at least one of the above three bearer services to conform with this International Standard. The scope of this International Standard does not include: _ the negotiation of service at call establishment time, _ the change of service during a call, and _ unidirectional services. This International Standard includes optional procedures for the provision of functions equivalent to the following public ISDN supplementary services: Subaddress and Multiple Subscriber Number. NOTE 1 - Supplementary services and other bearer services which can be used in conjunction with 64 kbit/s circuit switched bearer services specified in this International Standard are dealt with in other standards. NOTE 2 - Service specifications are based on information concerning the corresponding public ISDN service available at the time of publication of this International Standard. NOTE 3 - ITU-T treat Subaddressing and Multiple Subscriber Number as supplementary services. NOTE 4 - The use of the Direct Dial In supplementary service of a public ISDN for calls incoming to a PISN from a public ISDN is regarded as part of the basic services in a PISN. NOTE 5 - The use of the Calling Line Identification Presentation and Connected Line Identification Presentation supplementary services of a public ISDN for obtaining the Originating Number or the Connected Number of a call from or to a public ISDN is regarded as part of the basic services in a PISN. NOTE 6 - The provision (either explicitly or implicitly) by the user to the network, of its own number (Originating Number or Connected Number), and the provision of an Originating Number or a Connected Number by a PISN to another network is a part of the basic services in a PISN and not a part of the Calling Line Identification Presentation and Connected Line Identification Presentation supplementary services. Those supplementary services are concerned only with the presentation of the number from the network to the served PISN user.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of ISO 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. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.
ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 11574 was prepared by ECMA (as ECMA-142) and was adopted, under a special “fast-track
procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national
bodies of ISO and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 11574:1994), which has been technically revised.
Annexes A and B form a normative part of this International Standard. Annexes C and D are for information only.

Introduction
This International Standard is one of a series of standards defining services and signalling protocols applicable to Private
Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework
of International Standards for Open Systems Interconnection as defined by ISO/IEC.
This International Standard contains specifications of basic services.
This International Standard is based upon the practical experience of ECMA member companies and the results of their active
and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization
bodies. It represents a pragmatic and widely based consensus.

Section 1: General
1Scope
This International Standard specifies the service description and control aspects, including functional capabilities and
information flows, of standardised circuit-mode bearer services which may be supported by a Private Integrated Services
Network (PISN).
This International Standard includes the following basic services:
� Circuit-mode 64 kbit/s unrestricted 8 kHz structured bearer service category;
� Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for speech information transfer;
� Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for 3,1 kHz audio information transfer.
A PISN shall support at least one of the above three bearer services to conform with this International Standard.
The scope of this International Standard does not include:
� the negotiation of service at call establishment time,
� the change of service during a call, and
� unidirectional services.
This International Standard includes optional procedures for the provision of functions equivalent to the following public ISDN
supplementary services: Subaddress and Multiple Subscriber Number.
NOTE 1 - Supplementary services and other bearer services which can be used in conjunction with 64 kbit/s circuit switched bearer services
specified in this International Standard are dealt with in other standards.
NOTE 2 - Service specifications are based on information concerning the corresponding public ISDN service available at the time of
publication of this International Standard.
NOTE 3 - ITU-T treat Subaddressing and Multiple Subscriber Number as supplementary services.
NOTE 4 - The use of the Direct Dial In supplementary service of a public ISDN for calls incoming to a PISN from a public ISDN is regarded
as part of the basic services in a PISN.
NOTE 5 - The use of the Calling Line Identification Presentation and Connected Line Identification Presentation supplementary services of a
public ISDN for obtaining the Originating Number or the Connected Number of a call from or to a public ISDN is regarded as part of the
basic services in a PISN.
NOTE 6 - The provision (either explicitly or implicitly) by the user to the network, of its own number (Originating Number or Connected
Number), and the provision of an Originating Number or a Connected Number by a PISN to another network is a part of the basic services in
a PISN and not a part of the Calling Line Identification Presentation and Connected Line Identification Presentation supplementary services.
Those supplementary services are concerned only with the presentation of the number from the network to the served PISN user.
