Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Signalling
Protocols and Switching (SPS).
The present document 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) ATM transfer
capability and traffic parameter indication, as described below:
Part 1: "Protocol specification [ITU-T Recommendation Q.2961 Part 1 (1995), Part 2 (1997), Part 3 (1997),
Part 4 (1997), modified]";
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".
The present document details the access signalling system protocol aspects and switching functions required to support
the ATM transfer capability and the related traffic parameter indication at call and/or connection establishment time.

Global modifications to ITU-T Recommendations Q.2961.1

Insert the following clause (Scope).
Scope
This first part of EN 301 068 covers the support of additional traffic parameters for the Broadband Integrated Services
Digital Network (B-ISDN) at the T reference point or coincident S and T reference point as defined in ITU-T
B B B
Recommendation I.413 by means of the Digital Subscriber Signalling System No. two (DSS2) protocol for the pan-
European Broadband Integrated Services Digital Network (B-ISDN) as provided by European public telecommunication
operators.
It defines the DSS2 protocol procedures, formats and functions needed to support the identified ATM transfer
capabilities and the ATM traffic related additional capabilities.
The specifications provided by the present document allow for the signalling of the ATM transfer capabilities and of the
additional traffic parameters beyond the ones already specified by EN 300 443-1 for B-ISDN basic call/connection
control at the UNI. The additional traffic parameters support a Broadband Connection-Oriented Bearer Service (BCOB)
as specified in ITU-T Recommendation F.811.
The present document forms part of the DSS2 family of standards; it specifies extensions to EN 300 443-1 which
specifies the control protocol for point-to-point call/bearer connection, and does not repeat states, information elements,
messages and procedures contained therein, but only specifies extensions related to additional traffic parameter
indications.
This present document does not cover procedures for the negotiation and modification/re-negotiation of the ATM traffic
parameters.
