PREEFACE
The Common Functional Specifications (CFS) are to be the concise, coherent and
customized framework of the synthesis results of RACE Part I : IBC Developments and
Implementations Strategies.
This is the first issue of the RACE CFS. They are not yet complete nor are they
rigorous in their treatment of the various issues. They have been prepared by the system
sections of the RACE Projects via their participation in the RACE STG (Sub Technical Groups).
The specifications represent the first attempt by many participants in RACE at preparing
CFS. In some instances they have been prepared by a single project and are written as project
reports. Such CFS have been included as written because of the lack of opportunity to do
otherwise. It must be recognised however that they are the only set of documents describing the
system level output from the RACE programme and entering the public domain.
The work of enhancing the CFS, extending them, reconciling inconsistencies, improving
the presentation, etc. are ongoing tasks for the technical groups of RACE. They will continue
meeting throughout 1991 and 1992 with the above objectives. At the same time they will be
selecting appropriate parts of their work for contribution to the standardisation bodies of Europe
(ETSI, CEN/CENELEC, etc.) to assist in their work and to bring the results of the RACE
Programme to the attention of the other actors in the telecommunications sector of Europe.

RACE
RACE (Research and Development in Advanced Communications Technologies in
Europe) is a Community Programme to prepare for the 'Introduction of Integrated Broadband
Communication (IBC) taking into account the evolving ISDN and national introduction strategies,
progressing to community-wide services by 1995'.
RACE covers major aspects of terrestrial networks, satellites and mobile
telecommunications, including considerations on narrowband and broadband networks as well as
distribution networks. RACE is also concerned with telecommunications services, their
definition and exploitation by end-users.

1 INTRODUCTION
In this CFS a method for the specification of B-ISDN network capabilities is derived by using
connection types as a basis in a manner similar to that used in CCITT 1.340 (Blue Book,
Melbourne 1988) for the N-ISDN network capabilities. In the N-ISDN the specification of
network capabilities is mainly derived by:
the definition of a set of ISDN connection types, associated with a set of attributes with
certain values (CCITT 1.340),
other requirements described in CCITT Recommendations 1.310, 1.410, 1.411 of the Blue
Book.
The method of specifying ISDN connection types can be described as a four step process (a
precursor of this process involves some knowledge of the services to be supported; see section
3.1 below):
Step 1: Select a set of attributes, useful to describe ISDN connections,
e.g. Information Transfer Mode, Establishment of Connection,
Symmetry, Channel Rate, ... (cf. 1.140: "Attribute Technique ... ").
Step 2: Identify the possible attribute values (or value classes) for
these attributes, e.g. "Switched, semi-permanent, permanent" fo
"Establishment of Connection".
Step 3: Select a combination of specific attribute values to describe a
connection type.
Step 4:t a limited set of the combinations, if possible; these form
the Connection Types (in 1.340, this selection of combinations is
mainly based on a selection of 5 "dominant" attributes).

A connection type obtained by this method is therefore associated with a set of attributes with
certain values (they are still under study and will provided in section 4 of this CFS in 1991).
Step 4 is necessary, because not all of the combinations of attribute values of step 3 are of
practical use; some combinations will be impractical or may even be contradictory.
For the B-ISDN, the method used to get N-ISDN connection types has to be enlarged, taking
into account
