of ETSI standards", which is available free of charge from the ETSI Secretariat. Latest updates are available on the
ETSI Web server (http://www.etsi.fr/ipr or http://www.etsi.org/ipr).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

which are, or may be, or may become, essential to the present document.
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. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) Terminal Portability (TP)
supplementary service, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification".
The present document contains no parts related directly to conformance testing. All procedures related to the TP
supplementary service are contained within basic call control and consequently all conformance testing requirements are
specified within the basic call control test specifications. The optional call rearrangement procedures within the basic
call control become mandatory for the TP supplementary service and the support, or otherwise, of these procedures is
the determining factor in assessing an implementation's conformance to the present document.
In accordance with CCITT Recommendation I.130, 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 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.
The present document details the stage 3 aspects (signalling system protocols and switching functions) needed to
support the Terminal Portability (TP) supplementary service. The stage 1 and stage 2 aspects are detailed in
ETS 300 053 and ETS 300 054, respectively.
The present version updates the references to the basic call specifications.
