Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols &
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI),
and is now submitted for the Vote phase of the ETSI standards approval procedure.
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 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 2 aspects (functional capabilities and information flows) needed to support the
Meet-Me Conference (MMC) supplementary service. The stage 1 aspects are detailed in ETS 300 164
(1992). The individual calls in an MMC are each basic calls with no special signalling functions, therefore no
stage three standard is provided.

1 Scope
This standard defines the stage two of the Meet-Me Conference (MMC) supplementary service for the
pan-European Integrated Services Digital Network (ISDN) as provided by European public
telecommunications operators. Stage two identifies the functional capabilities and the information flows
needed to support the service description. The stage two description also identifies user operations not
directly associated with a call (see CCITT Recommendation I.130 [1]).
This standard is specified according to the methodology specified in CCITT Recommendation Q.65 [2].
This standard does not formally describe the relationship between this supplementary service and the
basic call, but where possible this information is included for guidance.
In addition this standard does not specify the requirements where the service is provided to the user via a
private ISDN. This standard does not specify the requirements for the allocation of defined functional
entities within a private ISDN; it does however define which functional entities may be allocated to 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.
The MMC supplementary service provides an user with the ability to arrange for a call between more than
two participants, all participants accessing a conference bridge.
No field of application and no conformance is specified to this standard. Therefore no method of testing is
available.
2 Normative references
This standard 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.
