SIST ETS 300 650 E1:2005 is the Slovenian edition of ETS 300 650 Edition 1 for the Integrated Services Digital Network (ISDN) Message Waiting Indication (MWI) supplementary service. It is a stage 1 service description from the user's point of view, defining how the network indicates that at least one message is waiting, mainly for mailbox services and their controlling users.

What does SIST ETS 300 650 E1:2005 specify?

SIST ETS 300 650 E1:2005 specifies the ISDN MWI supplementary service as a public network service for users connected by basic access or primary rate access. It describes the service behaviour, not the signaling protocol, and it is written for stage 1 use.

The scope covers:

• service provision and withdrawal,
• activation, deactivation, invocation and interrogation procedures,
• interworking with non-ISDNs and private ISDNs,
• interactions with other supplementary services listed in Clause 8.

The document also states what is outside scope: the human interface details, charging principles, and interactions not listed in Clause 8.

What are the key requirements of SIST ETS 300 650 E1:2005?

Clause 5 says the network uses MWI to tell a receiving user that a message is waiting, at the request of a controlling user. In practice, this is the core mailbox notification function that the service is built around.

Clause 6.1 requires provision and withdrawal by prior arrangement with the service provider. It also allows network options for registering controlling users' ISDN numbers and for offering the service on an access or ISDN number basis, which matters when the same receiving user has several associated numbers.

Clause 6.2.1.1 defines activation data such as the receiving user's ISDN number, the basic service, and optional information like invocation mode, message count, message identity, date/time, and the controlling user's ISDN number. This tells implementers what data the network may store and relay with the indication.

Clause 6.2.1.2 defines deactivation with the receiving user's ISDN number, the basic service, and invocation mode. When deactivation is accepted, the network may also invoke the service to tell the receiving user that no messages are available.

Clause 6.2.3 defines three invocation modes:

• deferred mode - the indication is given on an outgoing call attempt,
• immediate mode - the indication is given independently of any call,
• combined mode - both behaviours apply.

That distinction matters because it changes when the receiving user sees the alert and how the service is presented on the terminal.

Clause 6.3.1 lists the main rejection cases for activation and deactivation, including invalid numbers, missing subscriptions, prohibited interactions, lack of registration, delivery failure, and network limits. For operations teams, these are the reasons the network must report back when a request cannot be completed.

Clauses 7 and 8 set the interworking and interaction rules. MWI can be received in the Public Switched Telephone Network (PSTN), must cooperate with private ISDNs, must never be diverted by call forwarding, and can be used with multiple subscriber number so that each assigned ISDN number can be handled separately.

What terms does SIST ETS 300 650 E1:2005 define?

• MWI - Message Waiting Indication, the service that alerts the receiving user that a message is waiting.
• Receiving user - the user who gets the message waiting indication.
• Controlling user - the user who activates and deactivates MWI, typically the mailbox side.
• ISDN number - a number that follows the ISDN numbering plan and structure.
• Service provider - the entity that offers the MWI supplementary service to users.
• Mail box - a system inside or outside the public network that can handle mail.
• Basic access - the access type used to connect a user to the ISDN service.
• Primary rate access - the higher-capacity access type used to connect a user to the ISDN service.

Who uses SIST ETS 300 650 E1:2005?

SIST ETS 300 650 E1:2005 is used by public network operators and service providers that offer mailbox-related notification services over ISDN. It is also relevant to private ISDN operators because the standard requires cooperative interworking between public and private ISDNs.

Engineers and system integrators use it when designing the service logic for activation, deactivation, and message indication. Quality managers and buyers use it to check whether an ISDN platform supports the right service model, especially the deferred, immediate, or combined invocation behaviour.

What does the SIST ETS 300 650 E1:2005 document contain?

SIST ETS 300 650 E1:2005 contains a stage 1 service description, not a testing procedure. It is organized into clauses on scope, normative references, definitions, abbreviations, description, procedures, intercommunication considerations, and interaction with other supplementary services.

Clause 6 is the most detailed part. It covers provision and withdrawal, normal procedures, exceptional procedures, and the subscription and network options shown in Tables 1 and 2. Those tables set out items such as invocation mode, registration of controlling-user numbers, and network options for active instances.

Clause 7 covers interworking with non-ISDNs and private ISDNs. Clause 8 maps the behaviour against other supplementary services, including advice of charge, call waiting, diversion services, multiple subscriber number, remote control, and others.

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.

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
