Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document describes the general requirements and service aspects for the Message Waiting Indication
(MWI) supplementary service for both, PSTN and ISDN subscriber lines and only for the receiving user parts. It does
not deal with the underlying technology or kind of network used to provide the service.
In accordance with ITU-T Recommendation I.130 [1], the following three level structures are 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.
The present document details the stage 1 aspects (overall service description) for the Message Waiting Indication
(MWI) supplementary service.

1 Scope
The present document defines the stage one of the Message Waiting Indication (MWI) supplementary service for the
pan-European network as provided by European telecommunications operators. Stage one is an overall service
description from the user's point of view (see ITU-T Recommendation I.130 [1]), but does not deal with the details of
the human interface itself.
The present document provided hereafter takes into account ETS 300 650 [2] for an ISDN MWI service and it provides
a wider scope of the service description. It shall be noted that ETS 300 650 [2]:
• covers only ISDN situations;
• includes both the receiving user's and the controlling user's perspective instead of concentrating on the service as
seen by the receiving user;
• is a restricted view on the facilities that need to be offered commercially (e.g. multiple Mailbox providers);
• includes some constraints.
NOTE 1: In case of conflict between the present document and ETS 300 650 [2], it is assumed that
ETS 300 650 [2] will take precedence.
NOTE 2: The detailed specifications of the procedures used by the controlling user to activate and deactivate the
MWI supplementary service are outside the scope of the present document. It can be based on ISDN
procedures (an example is given in ETS 300 650 [2]) or on other type of operations on other user-network
interfaces (e.g. leased lines etc.).
NOTE 3: It is worth noting that the network capabilities supporting the MWI supplementary service can be used for
other purposes e.g. notification of events other than related to Voice Mail e.g. E-mail.
NOTE 4: The definition of the Man Machine Interface (e.g. light, display, .) on the terminal equipment is outside
the scope of the present document.

4 Description
The Message Waiting Indication (MWI) supplementary service enables a receiving user (RU) to be informed that there
are one or more messages waiting in a message system.
The MWI supplementary service is typically used between a controlling user (CU, e.g. mailbox provider) and a user of
the message service provided (receiving user). The controlling user invokes the MWI supplementary service and the
receiving user receives the notification (or message waiting indication).
It can be activated or deactivated in the receiving user network, upon a request of the controlling user, and shall be
available for receiving users connected to PSTN or ISDN subscriber lines.
See annex C for an example of use of the service.
The MWI supplementary service enables the network, upon an invocation request of a Controlling user, to notify the
receiving user that at least one message is awaiting in a message system.

9 ETSI TR 101 895 V1.1.1 (2001-01)
The receiving user shall be notified by the network that a message is awaiting in the following situations:
• as an immediate notification, which is expected to be a persistent indication for the receiving user, as soon as
the MWI supplementary service has been invoked by the controlling user; and/or
• as a deferred notification, which is expected to be a general information message (e.g. announcement), when
the receiving user makes an outgoing call attempt after the MWI service has been invoked by the controlling
user.
Having received this notification, the receiving user can subsequently access the message system to have the message
delivered. The means by which the RU accesses and manages the message system are outside the scope of the present
document.
After this action has been completed, the controlling user may invoke the MWI supplementary service either:
• to deactivate the notification associated with the corresponding message; or
• to deactivate notifications in a global mode (i.e. for all messages in the message system at the time of the
notification, even if not yet delivered).
Depending on the situation (MWI service option), this operation shall result, as soon as the MWI supplementary service
has been invoked for notification deactivation by the controlling user in:
• an immediate notification of deactivation; or
• a deactivation of the deferred notification.
5 Procedures
5.1 Provision and withdrawal
The MWI supplementary service shall be provided to the receiving user after prior arrangement with the MWI service
provider or, as a network operator option, generally available. The MWI supplementary service shall be withdrawn at
the receiving user's request, or for administrative reasons.
• In the case of notification using modem transfer, it is assumed that the receiving user has appropriate capabilities
to receive information transferred. Also, as a MWI service option, the receiving user can be prevented from
receiving any notification;
• Provision of the MWI supplementary service shall be possible on an access or number basis.
As a network option, the receiving user can have a subscription option to register the controlling user numbers that can
activate and deactivate the MWI supplementary service. The maximum number of controlling users numbers that can be
registered for a receiving user shall be an integer value and is also a network operator option.
Depending on the MWI service provider option applying, the following subscription options can be made available to
the receiving user:
• only immediate notification (as soon as the MWI supplementary service has been invoked by a controlling user);
• only deferred notification (when the MWI supplementary service has been invoked by a controlling user and the
receiving user makes an outgoing call attempt);
• or both immediate and deferred notification.
The receiving user shall have a subscription option to allow or not an override of the default notification
(immediate/deferred) on a given invocation mode by the controlling users.

SIST-TP ETSI/TR 101 895 V1.1.1:2005
10 ETSI TR 101 895 V1.1.1 (2001-01)
Depending on a network operator option, the deferred notification can be:
• a general audible indication (e.g. announcement); and/or
• a general visual indication; and
• additional information.
5.2 Normal procedures
5.2.1 Registration and erasure
Not applicable.
5.2.2 Activation and deactivation
In order to allow the receiving user to be appropriately notified, it is assumed that actions need to be undertaken by the
controlling user:
• activation of the MWI supplementary service for a specific receiving user;
• deactivation of the MWI supplementary service for a specific receiving user.
Several controlling users can simultaneously activate or deactivate the MWI supplementary service for a given
receiving user.
NOTE: The following information has to be used for achieving these operations:
• the applicable basic service (ISDN);
• the type of operation (activation/deactivation);
• the kind of notification (immediate and/or deferred) to be provided;
and as an option:
• information provided by the controlling user and to be transferred transparently to the receivi
