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 telephony 3,1 kHz teleservice.
The stage 2 and stage 3 aspects are detailed in a general form in CCITT Recommendation Q.71 (an ETSI
version is under development) and ETS 300 102 (1990), respectively.

1 Scope
This standard defines the stage one of the telephony 3,1 kHz teleservice 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 the service is provided to the user via a
private ISDN.
This standard does not specify the additional requirements where the 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.
Charging principles are outside the scope of this standard.
The values of the general attributes are outside the scope of this standard.
The telephony 3,1 kHz teleservice provides users with the ability for real time two-way speech
conversation via the public ISDN.
This standard is applicable to the stage two and stage three standards for the ISDN telephony 3,1 kHz
teleservice. 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".
