Foreword
This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
In accordance with CCITT Recommendation I.130 [1], the following three level structure is used to
describe the supplementary telecommunications services as provided by European public
telecommunications operators under the pan-European Integrated Services Digital Network (ISDN):
- Stage 1: is an overall service description, from the user's standpoint;
- Stage 2: identifies the functional capabilities and information flows needed to support the service
described in stage 1; and
- Stage 3: defines the signalling system protocols and switching functions needed to implement the
service described in stage 1.
This ETS details the stage 1 aspects (overall service description) for the Freephone (FPH) supplementary
service. The stage 2 and stage 3 aspects are detailed in ETR 209 (1996) and ETS 300 210 (1996),
respectively.
Transposition dates
Date of adoption of this ETS: 1 March 1996
Date of latest announcement of this ETS (doa): 30 June 1996
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 December 1996
Date of withdrawal of any conflicting National Standard (dow): 31 December 1996

1 Scope
This standard defines the stage one of the Freephone (FPH) supplementary service for the pan-European
Integrated Services Digital Network (ISDN) as provided by European public telecommunications
operators. Stage one is an overall service description from the user's point of view (see CCITT
Recommendation I.130 [1]), but does not deal with the details of the human interface itself.
This standard defines the interworking requirements of private ISDNs with the public ISDN.
In addition this standard specifies the base functionality where FPH supplementary service is provided to
the user via a private ISDN.
This standard does not specify the additional requirements where FPH supplementary service is provided
to the user via a telecommunications network that is not an ISDN but does include interworking
requirements of other networks with the public ISDN.
Interactions with supplementary services not listed in clause 8 are outside the scope of this standard.
Charging principles are outside the scope of this standard, unless specific service requirements are
stated. These requirements deal with the allocation of certain call charges to particular users.
The FPH supplementary service enables to allocate to the served user the charges for calls placed to the
freephone number.
The FPH supplementary service is applicable to all circuit-switched telecommunication services.
This standard is applicable to the stage two and stage three standards for the ISDN FPH supplementary
service. The terms "stage two" and "stage three" are also defined in CCITT Recommendation I.130 [1].
Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as
authorisation leaving freedom, or as a capability or possibility), this shall be reflected in the text of the
relevant stage two and stage three standards.
Furthermore, conformance to this standard is met by conforming to the stage three standards with the
field of application appropriate to the equipment being implemented. Therefore, no method of testing is
provided for this standard.
2 Normative references
This standard incorporates by dated or 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 standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.

telecommunication services supported by an ISDN and network capabilities of
an ISDN".

3 Definitions
For the purposes of this standard, the following definitions apply:
Integrated Services Digital Network (ISDN): see CCITT Recommendation I.112 [2], paragraph 2.3,
definition 308.
Service; telecommunications service: see CCITT Recommendation I.112 [2], paragraph 2.3, definition
201.
Supplementary service: see CCITT Recommendation I.210 [3], paragraph 2.4.
ISDN number: a number conforming to the numbering plan and structure specified in CCITT
Recommendation E.164 [5].
Basic access: see CCITT Recommendation Q.9 [4], paragraph 1, definition 1551.
Primary rate access: see CCITT Recommendation Q.9 [4], paragraph 1, definition 1552.
Served user: the customer who has subscribed to the FPH supplementary service.
Freephone number: a set of digits assigned by the service provider to a served user upon subscription to
the FPH supplementary service. The freephone number forms the subscriber number part of the ISDN
number, and in conjunction with a service access code, the freephone number forms the national part of
an ISDN number (see CCITT Recommendation E.164 [5]).
Freephone call: a call made to the freephone number.
Service access code: digits assigned to the FPH supplementary service, which forms the national
destination code part of an ISDN number. In conjunction with a freephone number, the service access
code forms the national part of an ISDN number.
Access arrangement: installations (e.g. PABX) and/or terminals connected to the served user's access
(e.g. primary rate access).
Routeing area: an area from which calls using a given freephone number are routed to one access
arrangement or to a set of access arrangements according to other requirements.
Service profile: a record containing instructions for freephone call handling.

5 Description
5.1 Core requirements
The FPH supplementary service shall be available to users who are attached to the network via a basic
access or a primary rate access.
The FPH supplementary service enables to allocate to the served user the charges for calls placed to the
freephone number.
NOTE 1: For an interim period, some service providers may allocate charges to the calling user.

5.2 Optional requirements
5.2.1 General
The optional requirements contain functionalities additional to the core requirements, that customise the
service according to specific subscriber's needs. These additional parts may be either offered to all
service provider's customers, or to a group or even to a single customer.
Some possible service provider's options are listed hereafter, but the service provider may offer other
additional options.
5.2.2 Time dependent control
The served user is enabled to modify the handling of the call according to the time interval (e.g., time of
day, day of week) in which the call is placed.
5.2.3 Time dependent routeing
The served user is enabled to specify the routeing destination(s), e.g. access arrangement
