Foreword
IS0 (the International Organization for Standardization) and IEC (the International 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 committees collaborate in fields of mutual interest. Other
international organizations, 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,
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.
International Standard ISO/IEC 13242 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 6, Telecommunications and information exchange
between systems.
Annex A of this International Standard is 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 Standards for Open Systems Interconnection
as defined by ISO/IEC.
This particular International Standard specifies the Route Restriction Class additional network
feature.

Information technology - Telecommunications and
information exchange between systems - Private
Integrated Services Network - Specification, functional
model and information flows - Route Restriction Class
additional network feature
1 Scope
This International Standard specifies the Route Restriction Class additional network feature
(ANF-RRC), which is applicable to various basic services supported by Private Integrated Services
Networks (PISN). Basic services are specified in ISO/IEC 11574.
ANF-RRC permits a Route Access Class (RAC) to be associated with a call to indicate its entitlement
.
to use certain facilities during routeing.
Additional network feature specifications are produced in three stages, according to the method
described in CCITT Recommendation I. 130 for supplementary services. This International Standard
contains the stage 1 and stage 2 specifications of ANF-RRC. The stage 1 specification (clause 6)
specifies the feature as seen by an entity which generates, receives, and acts on the RAC. The stage 2
specification (clause 7) identifies the functional entities involved in the feature and the information
flows between them.
2 Conformance
In order to conform to this International Standard, a Stage 3 Standard shall specify signalling
protocols and equipment behaviour that are capable of being used in a PISN which supports the
feature 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 clause 6 and clause 7 which are
relevant to the interface or equipment to which the Stage 3 Standard applies.
3 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions
