Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the
development of International Standards through technical committees established by the respective organization to deal with
particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.
ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 15505 was prepared by ECMA (as ECMA-241) and was adopted, under a special “fast-track
procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national
bodies of ISO and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 15505:1997), which has been technically revised.

ISO/IEC 15505:2000(E)
Introduction
This International Standard is one of a series of standards defining services and signalling protocols applicable to Private
Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework
of International Standards for Open Systems Interconnection as defined by ISO/IEC.
This International Standard specifies the Message Waiting Indication supplementary service.
This International Standard is based upon the practical experience of ECMA member companies and the results of their active
and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization
bodies. It represents a pragmatic and widely based consensus.

INTERNATIONAL STANDARD ISO/IEC 15505:2000(E)
Information technology — Telecommunications and information exchange between
systems — Private Integrated Services Network (PISN) — Specification, Functional
Model and Information Flows — Message Waiting Indication Supplementary Service
1Scope
This International Standard specifies supplementary service Message Waiting Indication (SS-MWI), which is related, but not
limited, to various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in
ISO/IEC 11574.
This supplementary service MWI enables a Served User to be sent a Message Waiting Indication and also enables this
Message Waiting Indication to be cancelled.
Service specifications are produced in three stages, according to the method described in CCITT Rec. I.130. This International
Standard contains the stage 1 and stage 2 specifications of SS-MWI. The stage 1 specification (clause 6) specifies the
supplementary service as seen by users of PISNs. The stage 2 specification (clause 7) specifies the functional entities involved
in the supplementary service and the information flows between them.
2 Conformance
In order to conform to this International Standard, a stage 3 standard shall specify signalling protocols and equipment
behaviour that are capable of being used in a PISN which supports the supplementary service specified in this International
Standard. This means that, to claim conformance, a stage 3 standard is required to be adequate for the support of those aspects
of clause 6 (stage 1) and clause 7 (stage 2) which are relevant to the interface or equipment to which the stage 3 standard
applies.
3 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this
International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not
apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of
applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the
normative document referred to applies. Members of IEC and ISO maintain registers of currently valid International Standards.

6.1 Description
6.1.1 General description
The supplementary service MWI enables a Served User to be sent a Message Waiting Indication and also enables this Message
Waiting Indication to be cancelled.
NOTE 1 The Message Waiting Indication is sent on activation by the Message Centre.
NOTE 2 The Message Waiting Indication is cancelled on deactivation by the Message Centre.
A Served User can receive separate MWIs for each of the services for which there is a message waiting.
NOTE A service for which there is a message waiting would normally use the related basic service to retrieve that message.
6.1.2 Qualifications on applicability to telecommunication services
This supplementary service does not apply directly to any basic telecommunication service. However, a MWI relates to a basic
service for which there are messages waiting.
6.2 Procedures
6.2.1 Provision / withdrawal
SS-MWI may be provided or withdrawn after pre-arrangement with the service provider or may be generally available to all
users.
6.2.2 Normal procedures
6.2.2.1 Activation, deactivation and interrogation
The PISN shall provide activation / deactivation by the Message Centre. In addition, the PISN may provide interrogation by
the Served User.

ISO/IEC 15505:2000(E)
To activate SS-MWI, the Message Centre shall supply the PISN number and the service for which there is a message waiting
and may, as an implementation option, add any combination of the following pieces of information: the identity of the Message
Centre; the number of messages waiting for the Served User for that service; the address of the user that left a message; the
time when a message was left; the priority of the highest priority message waiting for that service. After activation, SS-MWI
may be activated again whenever the number of waiting messages changes.
To deactivate SS-MWI, the Message Centre shall supply the PISN number and the service for which there is no longer a
message waiting.
As a result of activation, a MWI shall be sent to the Served User. The MWI may include information on messages waiting, if
provided by the Message Centre. As a result of deactivation, the MWI at the Served User, for the service concerned, shall be
cancelled.
When the Message Centre activates or deactivates SS-MWI at the Served User, it shall be provided with an indication of
acceptance.
When the Served User interrogates SS-MWI for a particular service, the Message Centre shall provide the Served User with an
indication of whether SS-MWI is activated for that service and may add, as an implementation option, any
