1 Scope
This TBR specifies the technical characteristics to be provided by Terrestorial Trunked Radio (TETRA)
terminal equipment which is capable of connecting and inter-working with a public telecommunications
network and which uses the TETRA technology. It applies only to terminal equipment intended for police
and emergency services operating within European harmonised frequency bands in the range 380 MHz to
383 MHz and 390 MHz to 393 MHz.
NOTE 1: These frequency bands may be extended by an additional 2 MHz at a later time.
The objective of this TBR is to ensure that no disturbance occurs to the public telecommunications
network, to ensure inter-working between public telecommunications networks and TETRA terminals and
TETRA terminal to TETRA terminal so that communication can be routed successfully through the
applicable network(s).
The requirements in this TBR apply together with the attachment requirements for the appropriate public
telecommunications network and the requirements of any other applicable TBR. It does not add to, or
reduce, the attachment requirements unless there is a particular effect on the network which is unique to
TETRA.
NOTE 2: Appropriate public telecommunications network refers to the TBR for basic rate
Integrated Services Digital Network (ISDN), the TBR for primary rate ISDN or the
national regulations (implementing ETS 300 001) for Public Switched
Telecommunications Network.
TETRA terminal equipment consists of several elements. This TBR is structured to allow testing and
approval of the individual elements as separate items. Due to the need for effective use of the radio
spectrum, the essential air interface characteristics have to be tested. For each essential requirement a
test is given including measurement methods.
Requirements apply to the public network interface and the Radio Frequency (RF) interface of the
equipment, which may be stimulated to perform the tests by additional equipment.
In this TBR there are no additional Electromagnetic Compatibility (EMC) requirements in terms of the
Terminal Directive 91/263/EEC [13], article 4c.
NOTE 3: Technical requirements for EMC performance and testing of the equipment are
covered by the relevant standards applicable to the EMC Directive 89/336/EEC.
Terminal equipment may be subject to additional requirements in other applicable Common Technical
Requirements (CTRs), or European Directives depending on the functionality (i.e. primary functions).
