Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 1 of a multi-part standard covering the Digital Subscriber Signalling System No. two
(DSS2) protocol specification for the Broadband Integrated Services Digital Network (B-ISDN) Closed
User Group (CUG) supplementary service, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 5: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".
NOTE: The final structure of the parts containing the test specifications is currently under
study.
In accordance with CCITT Recommendation I.130, the following three level structure is used to describe
the supplementary telecommunication services as provided by European public telecommunications
operators under the pan-European B-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.
This ETS details the stage 3 aspects (signalling system protocols and switching functions) needed to
support the CUG supplementary service. The stage 1 and stage 2 aspects of the equivalent N-ISDN
supplementary service are detailed in ETS 300 136 and ETS 300 137, respectively, and these have been
assumed as appropriate to be the foundation of the equivalent B-ISDN supplementary service
specifications.
Transposition dates
Date of adoption of this ETS: 22 May 1998
Date of latest announcement of this ETS (doa): 31 August 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 28 February 1999
Date of withdrawal of any conflicting National Standard (dow): 28 February 1999

Endorsement notice
The text of ITU-T Recommendation Q.2955.1 (1996) was approved by ETSI as an ETS with agreed
modifications as given below.
NOTE: New or modified text is indicated using sidebars. In addition, underlining and/or strike-
out are used to highlight detailed modifications where necessary.
subclause 1.1
Replace subclause 1.1 by:
1.1 Scope
This first part of ETS 300 770 specifies the stage three of the Closed User Group (CUG) supplementary
service for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as provided by
European public telecommunications operators at the T reference point or coincident S and T
B B B
reference point (as defined in ITU-T Recommendation I.413 [1]) by means of the Digital Subscriber
Signalling System No. two (DSS2) protocol. Stage three identifies the protocol and procedures and
switching functions needed to support a telecommunication service (see ITU-T Recommendation
I.130 [2]).
In addition, this ETS specifies the protocol requirements at the T reference point where the service is
B
provided to the user via a private B-ISDN.
This ETS does not specify the additional protocol requirements where the service is provided to the user
via a telecommunications network that is not a B-ISDN.
The CUG supplementary service enables users to form groups, to and from which access is restricted. A
specific user may be a member of one or more closed user groups. Members of a specific closed user
group can communicate amon
