1 Scope
This European Telecommunication Standard (ETS) defines terms commonly used in ETSs on the subject
of Private Telecommunication Networks (PTNs). The purpose of defining terms and definitions is to guide
the further specification of PTN capabilities and to permit consistency of interpretation between ETSs
containing such specifications.
The terms and definitions given in this ETS apply to the technical aspects of PTNs. They do not address
legal or regulatory issues.
An ETS shall be deemed to be in compliance with this ETS if it uses terms with the meanings as defined
by this ETS.
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] CCITT Recommendation E.164 (1991): "Numbering plan for the ISDN era".

4 Terms and definitions
The following subclauses are arranged in logical order. An alphabetical index is to be found at the end of
this ETS.
NOTE: Draft IEC 50(715) has been used as the basis for the preparation of this ETS. The
suitability of other definitions of that document will be considered as a subject arises.
4.1 Public
An attribute indicating that the application of an item qualified by "public", e.g. a network, a unit of
equipment, a service, is offered to the general public. This attribute does not indicate any aspects of
ownership.
NOTE: This definition does not include legal or regulatory aspects.

ETS 300 415: February 1995
4.2 Private
An attribute indicating that the application of an item qualified by "private", e.g. a network, a unit of
equipment, a service, is offered to a pre-determined set of users. This attribute does not indicate any
aspects of ownership.
NOTE: This definition does not include legal or regulatory aspects.
4.3 Private Telecommunication Network (PTN)
A network serving a pre-determined set of users (different from a public network which provides services
to the general public). The attribute "private" does not indicate any aspects of ownership.
NOTE 1: This definition does not include legal or regulatory aspects.
NOTE 2: PTNs are sometimes referred to as Corporate Telecommunication Networks
(CTNs). PTNs may extend over large geographical areas. This definition does not
imply any specific implementation.
NOTE 3: It is the intention to align the definition of "PTN" with that of "Private Integrated
Services Network (PISN)" as defined by ISO/IEC 11579-1. This will facilitate the
evolution towards the consistent world-wide use of the term "PISN". This will not
invalidate the scope of the services standardized by ETSI for PTNs.
4.4 Private Telecommunication Network eXchange (PTNX)
A PTN nodal entity that provides automatic switching and call handling functions used for the provision of
telecommunication services. The nodal entity can be implemented by one or more pieces of equipment
located on the premises of the private network administrator or by equipment co-located with, or physically
part of, a public network.
NOTE 1: If applicable, a PTNX provides to users of the same and/or other private tele-
communication network exchanges:
- telecommunication services within its own area; and/or
- telecommunication services from the public ISDN; and/or
- telecommunication services from other public or private networks; and/or
- within the context of a private telecommunication network, telecommunication
services from other private telecommunication network exchanges.
NOTE 2: It is the intention to align the definition of "PTNX" with that of "Private Integrated
services Network eXchange (PINX)" as defined by ISO/IEC 11579-1. This will facilitate
the evolution towards the consistent world-wide use of the term "PINX".
A PTNX may perform the functions of one or more of the node types given in subclauses 4.4.1 and 4.4.2.
4.4.1 Integrated Services Private Branch eXchange (ISPBX)
The implementation of a PTNX offering ISDN-like capabilities, separate from public network equipment.
NOTE: An ISPBX is usually located on the premises of a private network administrator.
4.4.2 Integrated Services CenTralized eXchange (ISCTX)
The implementation of a PTNX offering ISDN-like capabilities, as part of public network equipment.
NOTE: An ISCTX is usually located on the premises of a public network operator.

4.5 Call related PTNX functionality
In addition to other functionality, a physical implementation of a PTNX can contain one or more of the
functionalities defined below. The use of the terms "end-PTNX", "transit-PTNX" and "gateway-PTNX"
