SIST TBR 006:2000 is the Slovenian standard equivalent to TBR 006 Edition 2 for Digital Enhanced Cordless Telecommunications (DECT). It specifies general terminal attachment requirements and type-examination tests for DECT terminal equipment that connects to a public telecommunications network through the DECT common interface.

In practice, it tells manufacturers, test labs, and approval bodies what to measure, how to set up the equipment, and how to judge pass or fail so the terminal does not disturb the public network and can interwork correctly with it.

What does SIST TBR 006:2000 specify?

SIST TBR 006:2000 covers the general attachment requirements for DECT terminal equipment and the procedures for type examination. It is written for equipment that can be connected to a public telecommunications network and uses DECT cordless communications for network access in the 1 880-1 900 MHz band.

The standard is organized into 17 clauses and a set of annexes. The main clauses move from scope, references, definitions, and general test conditions to detailed radio and receiver tests, synchronization, EMC, equipment identity, and efficient use of the radio spectrum.

Annex	What it covers
A	Bibliography
B	Procedures for test fixture calibration and radiated spurious emissions
C	Conducted spurious emissions
D	Test Support Profile (TSP)
E	Measurement of BER
F	Synchronization loss at the EUT by the LT
G	Requirements for PPs with direct PP to PP communication mode
H	Requirements for installation related issues
I	Essential requirements justification
J	Additions to ETS 300 175-2

The standard is based on the DECT Common Interface in ETS 300 175 parts 1 to 8. Annex J contains additions to ETS 300 175-2 and is meant to be read together with this TBR.

What are the key requirements of SIST TBR 006:2000?

Test preparation and equipment presentation

SIST TBR 006:2000 requires the applicant to identify the equipment model for type examination and to describe the equipment with PICS and PIXIT information, environmental test conditions, host-connected equipment, and an applicant's declaration. Clause 4 also states when type tests apply to receiver-only equipment, transmitters, analogue ports, synchronization ports, IPEI-equipped PPs, all FP equipment, direct PP to PP communication, installation-related issues, and wireless relay stations.

This matters because the test lab must know exactly what configuration is being assessed. For a buyer or manufacturer, it means the declared features and connections are part of the compliance evidence, not just the hardware itself.

Test sites, test fixtures, and test support equipment

Clause 5 defines the test philosophy and the allowed test environments: open air test site, anechoic chamber, stripline coupler, indoor test site, standard position, test antenna, substitution antenna, and test fixture. It also describes the Lower Tester (LT) and Upper Tester (UT), the test set-ups, and the arrangements for intermodulation measurements.

This is important in practice because the result depends on how the EUT is presented and stimulated. The standard gives calibration and mode-of-use rules so that radiated and conducted measurements can be repeated and compared between laboratories.

Test conditions, power sources, and host-connected equipment

Clause 6 sets nominal and extreme test conditions, power source requirements, and temperature-related conditions for testing. It also gives two ways to handle host-connected equipment and plug-in cards: as composite equipment or with a test jig and three hosts.

This means the same EUT may need to be checked under different supply and host arrangements. For procurement or quality teams, it helps define whether a product is being approved as a standalone item or as part of a larger host system.

Radio performance: frequency, timing, burst, and power

Clauses 7 to 10 cover RF carrier accuracy and stability, timing parameters, transmission burst behavior, and transmitted power. Clause 7 refers to ETS 300 175-2 for carrier accuracy, while Clause 8 covers packet timing jitter, reference timing accuracy of a RFP, and packet transmission accuracy of a PP.

Clause 9 and Clause 10 deal with burst timing and transmitted power, including Normal Transmitted Power (NTP), transmitter attack and release time, and the special handling of integral antennas versus external antenna connections. In practice, these tests check that the equipment transmits at the right time, with the right power, and without overdriving the air interface.

RF modulation and unwanted emissions

Clause 11 addresses RF carrier modulation, and Clause 12 covers unwanted RF power radiation. The unwanted emission tests are split into emissions due to modulation, transmitter transients, intermodulation, and spurious emissions when a transmit channel is allocated.

This matters because DECT terminals operate in a shared radio spectrum. The tests are designed to show that the equipment keeps unwanted radiation low enough not to disturb other users or other DECT channels.

Receiver performance and robustness

Clause 13 covers radio receiver sensitivity, reference BER, interference performance, blocking, receiver intermodulation performance, and spurious emissions when the PP has no allocated transmit channel. Annex E supports BER measurement, and Annex F gives a procedure for measuring synchronization loss by the LT.

These requirements tell a test lab how well the receiver copes with wanted and unwanted signals. For users, this is the part of the standard that links laboratory performance to real-world call quality and resilience.

Synchronization, EMC, and spectrum use

Clause 14 covers the synchronization port for FP equipment, including master and slave operation, integrated GPS synchronization, and external GPS synchronization devices. Clause 15 points EMC performance and testing to the standards applicable to the EMC Directive. Clause 16 covers equipment identity testing, and Clause 17 covers efficient use of the radio spectrum through channel selection, channel confirmation, and channel release.

These clauses matter for installations with synchronized DECT systems and for regulatory approval. They also show that the standard is not only about RF power and sensitivity, but also about stable network behavior, identification, and disciplined channel use.

What terms does SIST TBR 006:2000 define?

• Antenna diversity - A Radio Fixed Part (RFP) can choose different antenna properties, such as gain or polarization, to improve practical coverage for each bearer.
• Bearer handover - A MAC-layer internal handover that changes the underlying bearers while keeping the service to the DLC layer running.
• Cell - The coverage area served by one FP antenna system, including a leaky feeder if used.
• Central Control Fixed Part (CCFP) - The central grouping within an FP that controls one or more RFPs.
• Conducted measurements - Measurements made by direct electrical connection to the equipment under test.
• DECT-like carrier - A modulated DECT RF carrier used for interference testing that matches ETS 300 175-2 frequency and timing and uses a pseudo-random modulation sequence.

Who uses SIST TBR 006:2000?

Manufacturers of DECT terminal equipment use SIST TBR 006:2000 to design products for type examination and to prepare the required declarations and test documentation. Test laboratories use it to set up the LT, UT, antennas, sites, fixtures, and verdict criteria needed for the measurements.

Approval and certification bodies use it to assess whether a DECT FP or PP can be attached to a public telecommunications network without causing disturbance. It is also relevant to system integrators and installers working with synchronized DECT systems, direct PP to PP communication, and other cases covered in Annexes G and H.

What changed in SIST TBR 006:2000 from the previous edition?

SIST TBR 006:2000 is the second edition and updates TBR 6 based on work on GAP/PAP and comments received. It also includes Annex J, which adds text on GPS synchronization to ETS 300 175-2.

TBR 6: January 1997
1 Scope
This Technical Basis for Regulation (TBR) covers the general attachment requirements for terminal
equipment for the Digital Enhanced Cordless Telecommunications (DECT) common interface.
This TBR contains the procedures and requirements for the type examination of DECT equipment.
DECT equipment capable of being physically attached to the public network also needs to meet the
appropriate attachment requirements. Speech attachment requirements are covered in TBR 10 (see
annex A).
This TBR is based on the DECT Common Interface (CI) given in ETS 300 175 parts 1 to 8 [1] to [8].
Annex J of this TBR contains changes to text in ETS 300 175-2 [2] and should therefore be read in
conjunction with this TBR. ETS 300 175-2 [2] will be amended in due course to reflect these changes,
following the normal ETSI amendment procedure.
This TBR specifies the technical characteristics to be provided by terminal equipment which is capable of
connection to a public telecommunications network and which uses DECT cordless communications for
network access. The cordless transmissions for such terminal equipment operate within the frequency
band 1 880 - 1 900 MHz.
The objective of this TBR is to ensure that no disturbance occurs to the public network, and to ensure
interworking between network and terminal so that calls can be routed successfully through the network,
but without any guarantee of terminal to terminal operation.
The requirements in this TBR applies together with the attachment requirements for the appropriate public
network (see note) and the requirements of any other relevant TBR. It does not add to or reduce the
attachment requirements unless there is a particular effect on the network which is unique to DECT.
NOTE: TBR for basic Integrated Services Digital Network (ISDN), TBR for primary rate ISDN,
or national regulations (implementing ETS 300 001) for Public Switched Telephone
Network (PSTN). Interconnection of a DECT terminal to a GSM network is still under
study; in due course, the scope statement may need amending to reflect this point.
A DECT terminal equipment comprises two elements, referred to as a Fixed Part (FP) and a Portable Part
(PP). This TBR is structured to allow type approval of the FP and PP as separate items.
Because of the need for effective use of the radio frequency spectrum, the air interface characteristics
between FP and PP are tested.
For each requirement, a test is given, including measurement methods. Requirements apply at the public
network interface of the terminal equipment, which may be stimulated to perform the tests by additional
equipment if necessary.
Terminal equipment may be subject to additional or alternative requirements in other Common Technical
Regulations (CTRs) depending on its functionality, in particular if it supports a service
