Foreword
This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
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 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 1 aspects (overall service description) for the Terminal Portability (TP)
supplementary service. The stage 2 and stage 3 aspects are detailed in ETS 300 054 (1991) and
ETS 300 055 (1991), respectively.

1 Scope
This standard defines the stage one of the Terminal Portability (TP) supplementary services for the pan-
European Integrated Services Digital Network (ISDN) as provided by European public telecommunications
operators. Stage one is an overall service description from the user's point of view, but does not deal with
the details of the human interface itself (see CCITT Recommendation I.130 [1].
This standard defines the interworking requirements of private ISDNs with the public ISDN.
In addition this standard specifies the base functionality where the service is provided to the user via 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 but does include interworking requirements of other
networks with the public ISDN.
Interactions with supplementary services not listed in clause 8 are outside the scope of this standard.
Charging principles are outside the scope of this standard.
The Terminal Portability (TP) supplementary service allows a user to move a terminal from one socket to
another within one given basic access during the active state of a call. It also allows a user to move a call
from one terminal to another terminal within one given basic access during the active phase of the call.
The portability of a terminal during the idle state is part of the basic access capabilities and does not
require any procedure.
The portability of a terminal in the call establishment and in the call clearing phases is not possible.
The TP supplementary service applies to some interactive circuit-switched telecommunication services
requiring the attendance of a human being, such as telephony, videotelephony, etc.
The TP supplementary service does not apply to non-interactive services such as facsimile, teletex,
mixed-mode, computer communication etc.
However, the network will not take any action to restrict its applicability.
It is a user's responsibility to
