1 Scope
This European Telecommunication Standard (ETS) defines the Terrestrial Trunked Radio (TETRA)
system supporting Voice plus Data (V+D). It specifies the stage one to three of the TETRA gateway to
Public Switched Telephone Network (PSTN). 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.
The PSTN gateway establishes a basic call, when SwMI detects an outgoing call from a TETRA user to
PSTN or the PSTN gateway detects an incoming call from PSTN to a TETRA user. The PSTN gateway
ensures that basic signalling required in the operation of the TETRA call and the PSTN call is maintained
across the gateway.
Circuit mode data modem types and data modem data connection set-up negotiations required to set-up
circuit mode data modems used in the analogue path between the PSTN gateway and a PSTN subscriber
are outside the scope of this ETS.
Support of TETRA and PSTN supplementary services is outside the scope of this ETS.
The PSTN gateway and the TETRA system is seen by the external network as it were a subscriber of the
external network. For incoming calls from PSTN two step dialling is used. The dialling requires Dual Tone
Multi Frequency (DTMF) capability from the PSTN user provided either by normal telephone set or by a
DTMF device external to the telephone set. Other means of incoming call dialling and a direct
communication, using other than PSTN subscriber lines, between TETRA system and the external
network exchange are outside the scope of this ETS.
End to end encryption is outside the scope of this ETS.
Gateway specifications are presented in three stages. The stage 1 specification specifies the PSTN
gateway service as seen by the TETRA system and by the PSTN subscriber. The stage 2 specification
identifies the functional entities involved in the gateway service and the information flows between them.
The stage 3 describes the service protocol related to the services. The described network layer services
and protocols apply for the Switching and Management Infrastructure (SwMI) and for the PSTN gateway
and to the keypad protocol for the PSTN subscriber using TETRA services.
This ETS describes the PSTN gateway as an Additional Network Function, which provides a PSTN
interface to the SwMI. The service description is informative and does not imply any implementation.

outgoing call: A call from a TETRA network to the PSTN.
PSTN: Any telecommunication network, which supports analogue PSTN subscriber signalling.
PSTN subscriber: An analogue PSTN user outside TETRA addressing domain and participates in a
PSTN gateway call.
TETRA user: A user within TETRA addressing domain and participates in a PSTN gateway call.

4 PSTN gateway stage 1 specification
4.1 Description
4.1.1 General description
The PSTN gateway enables calls to be set-up from a TETRA user to a PSTN subscriber and from
a PSTN subscriber to a TETRA user. Additionally, for the duration of the call, the PSTN gateway allows
TETRA signalling information to be passed from TETRA Switching and Management Infrastructure
(SwMI) to the external network user and from the external network user to the TETRA SwMI in
accordance with the TETRA Call Control (CC) procedures as defined in ET
