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 Direct Dialling In (DDI)
supplementary service. The stage 2 and stage 3 aspects are detailed in ETS 300 063 (1991) and ETS
300 064 (1991), respectively.

1 Scope
This standard defines the stage one of the Direct Dialling In (DDI) 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 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.
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.
The DDI supplementary service enables a user to call directly via a public ISDN a user on a private ISDN
by using the public ISDN numbering plan.
The DDI supplementary service is applicable to all telecommunication services.
This standard is applicable to the stage two and stage three standards for th
