1 Scope
This European Telecommunication Standard (ETS) defines the stage 1 specifications of the call hold
(HOLD) supplementary service for the Trans-European Trunked RAdio (TETRA) as provided by European
operators. Stage 1 is an overall service description from the users point of view but does not deal with the
details of the human interface itself.
This ETS specifies the service description of the supplementary service and the procedures to be
expected with successful and unsuccessful outcomes. In addition the ETS specifies the interactions with
other TETRA supplementary services and inter-working considerations.
Charging principles are outside the scope of this ETS.
The HOLD supplementary service enables a user to interrupt communications on an existing call and then
subsequently, if desired, re-establish communications.
2 Normative references
This ETS incorporates, by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] CCITT Recommendation I.130 (1988): "Method for the characterization of
telecommunication services supported by an ISDN and network capabilities of
an ISDN".
[2] ITU-T Recommendation Z.100 (1993): "Specification and Description Language
(SDL)".
3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
bearer service: A type of telecommunication service that provides the capability for the transmission of
signals between user-network interfaces.
served user: The user who places a call on hold. The served user may be either the calling user or the
called user.
Supplementary Service (SS): A supplementary service modifies or supplements a bearer service or a
teleservice. A supplementary service cannot be offered to a customer as a stand alone service. It should
be offered in combination with a bearer service or a teleservice.
Switching And Management Infrastructure (SwMI): All of the TETRA equipment for a Voice plus Data
(V+D) network except for subscriber terminals. The SwMI enables subscriber terminals to communicate
with each other via the SwMI.
teleservice: A type of telecommunications service that provides the complete capability, including
terminal equipment functions, for communication between users according to agreed protocols.
user B: The user placed on hold.

4.1 Description
4.1.1 General description
The served user shall be able to put individual calls on Call Hold (HOLD). Additionally the served user
shall be able to put multipoint calls on HOLD if he is the call owner.
The maximum number of calls on hold at any one time shall be an operator option. The served user shall
be informed at the stage when the maximum number of calls on hold has been reached.
4.1.1.1 Individual call
When the HOLD supplementary service is invoked, communication for the served user shall be
interrupted and the resource on the served users side shall be released from use by the existing call. The
resource of user B may be released from use depending on network implementation.
If the served user has more than one call on hold, he/she shall be able to switch from one call to another
call as required, privacy being provided between the calls. The served user shall also be able to
disconnect the active party, with the other parties still held, and shall be able to disconnect one of the held
parties whilst communicating with an active party.
After HOLD invocation, the served user shall be free to send a request to the network in order to, for
example:
- retrieve that call from hold;
- originate a new call;
- retrieve another call which is on hold;
- establish connection to an incoming call, e.g. a waiting call;
- invoke another supplementary service;
- interrogate the network.
