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 Felds of mutual interest.
Other international organizations, govemmental and non-govemmental, in liaison with ISO and IEC, also take part in
the work.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC I . 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.
International Standard ISO/IEC 13247 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 6, Telecommunications and information exchange between Systems.
Annexes A and B form an integral part of this International Standard. Annexes C to L are for information only.

Introduction
This International Standard is one of a series of International Standards def-ining Services and signalling protocols
applicable to Broadband Private Integrated Services Networks (B-PISNs). The series uses B-ISDN concepts as
developed by ITU-T and conforms to the fiamework of International Standards for Open Systems Interconnection as
defined by ISOAEC.
This particular International Standard specifies the signalling protocol for use at the Q reference Point for basic
call/connection control (B-QSIG-BC).

Inter-exchange signalling protocol- Basic call/connection control
1 Scope
This International Standard defines the signalling protocol for the purpose of basic call/connection control at the Q
reference Point between Private Integrated Services Network Exchanges (PINXs) connected together within a
Broadband Private Integrated Services Network (B-PISN) employing Asynchronous Transfer Mode (ATM). This
International Standard is gart of the B-QSIG signalling System.
The Q reference Point is defined in ISO/IEC 11579-1.
This International Standard is an application of the signalling protocol that forms part of the ATM Forum ’s PNNI 1 .O
specification, which in turn is based on ITU-T Recommendation 4.293 1, including the provisions for symmetrical
Operation described in annex H of recommendation Q.293 1. Technical differentes compared with the signalling
protocol specified in PNNI 1 .O are summarized in annex J. Guidelines for interworking between a network employing
the signalling protocol specified in this International Standard and a network employing the ATM Forum ’s PNNI 1.0
specification are given in annex L.
This International Standard is applicable
