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 [4], the following three level structure is used to
describe the supplementary telecommunication 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 stand-point;
- 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 Message Waiting Indication
(MWI) supplementary service. The stage 3 aspects are detailed in ETS 300 745-1 and ETS 300 754-1.
Transposition dates
Date of adoption of this ETS: 19 June 1998
Date of latest announcement of this ETS (doa): 30 September 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 March 1999
Date of withdrawal of any conflicting National Standard (dow): 31 March 1999

1 Scope
The present document defines the stage one of the Message Waiting Indication (MWI) supplementary
service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public
network operators. Stage one is an overall service description from the user's point of view (see
CCITT Recommendation I.130 [4]), but does not deal with the details of the human interface itself.
This ETS defines the interworking requirements of private ISDNs with the public ISDN.
Interactions with supplementary services not listed in clause 8 are outside the scope of this ETS.
The MWI supplementary service is provided independently of a call and is therefore applicable to a
number of telecommunication services.
Charging principles are outside the scope of this ETS.
The MWI supplementary service enables the network, upon the request of a controlling user to indicate to
the receiving user, that there is at least one message waiting.
NOTE: The MWI supplementary service is typically used between a mailbox service provider
(controlling user) and a user (receiving user) of the mailbox service provided.
This ETS is applicable to the stage two and stage three standards for the ISDN MWI supplementary
service. The terms "stage two" and "stage three" are also defined in CCITT Recommendation I.130 [4].
Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as authorization
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 ETS is met by conforming to the stage three standard with the field of
application appropriate to the equipment being implemented. Therefore, no method of testing is provided
for this ETS.

This ETS 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 ETS
only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.

5 Description
The Message Waiting Indication (MWI) supplementary service shall be available to users who are
connected to the network via a basic access or primary rate access.
The MWI supplementary service enables the network, upon the request of a controlling user to indicate to
the receiving user, that there is at least one message waiting. The indication is delivered to the receiving
user:
- when the MWI supplementary service is activated for a certain basic service and the receiving user
makes an outgoing call attempt; and/or
- as soon as the MWI supplementary service has been activated or deactivated.
NOTE: Having received this indication, the receiving user can subsequently access the mail
box, to have the mail delivered. The means by which the receiving user accesses and
manages the mail box are outside the scope of the
