Foreword
This second edition Technical Basis for Regulation (TBR) has been produced by the Special Mobile Group
(SMG) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This TBR covers the requirements for GSM Telephony (speech).
This TBR contains the procedures and requirements for the approval testing of GSM terminal equipment
for speech.
The requirements of other TBRs apply in addition to this TBR.
For each test, supplementary information is provided, giving a justification why this item has been selected
for regulatory testing, and a reference to the relevant article of the Terminal Directive [1].
This TBR is based on the ETS 300 607-1 (GSM 11.10-1 version 4.15.1) [2].
This TBR 20 corresponds to TC-SMG TBR 20 version 4.0.1 and is a result of further work within TC-SMG.
NOTE: This TBR for Phase 2 may be developed in stages. The first release will include, as a
minimum, all of the basic Phase 2 requirements for full rate and primary band.
Subsequent releases will include additional requirements.

1 Scope
This Technical Basis for Regulation (TBR) specifies the technical requirements to be met by terminal
equipment capable of connecting to a public telecommunications network. These requirements apply to
terminals for Phase 2 of the public land mobile radio service, operating in the 900 MHz band with a
channel separation of 200 kHz, utilizing constant envelope modulation and carrying traffic channels
according to the Time Division Multiple Access (TDMA) principle.
This TBR specifies the requirements for GSM Telephony (speech) for the GSM900 version of the Global
System for Mobile communications (GSM).
For each test purpose and its corresponding conformance requirement, a reference is given to
ETS 300 607-1 (GSM 11.10-1) [2]. The requirements apply to speech transmission.
The measurement uncertainty is handled, as described in ETS 300 607-1 (GSM 11.10-1) [2].
This TBR covers the essential requirements of the Terminal Directive 91/263/EEC [1] Article 4g.
Articles 4d, 4e, and 4f are covered by TBR 19.
The Terminal Directive 91/263/EEC Articles 4a and 4b are covered by other directives, and, therefore, not
by this TBR.
In this TBR, there are no Electromagnetic Compatibility technical requirements in terms of the Terminal
Directive 91/263/EEC, Article 4c.
NOTE 1: Technical Requirements for EMC performance and testing of the equipment are
covered by the relevant standards applicable to the EMC Directive 89/336/EEC,
annex A.
Terminal equipment may be subject to additional requirements in other Common Technical Regulations
(CTR) depending on the equipments functionality.
ETS 300 607-1 (GSM 11.10-1) [2] constitutes the conformance test suite for GSM. The verification of the
conformance requirements in this TBR is based on the tests described in this reference. The set of
requirements in ETS 300 607-1 (GSM 11.10-1) [2] and the set of requirements in this TBR need not be
identical.
Some requirements only apply to specific types of mobile station (e.g. data tests only apply to mobile
stations with a data facility). The TBR also indicates the specific test which shall be carried out for each
mobile station type.
An active accessory is covered by this TBR if it modifies the terminal performance in an aspect which
affects conformance to essential requirements.
NOTE 2: Only active devices are subject to this TBR. Accessories may be tested with specific
terminals, and either approved for use with those terminals only, or may possibly be
approved for use with a wider range of terminals, depending on the nature and effect
of the accessory.

2 Normative references
This TBR 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 revision of any of these publications apply
to the requirements specified in this TBR, only when incorporated in it by amendment or revision. For
undated references the latest edition of the publication referred to applies.

4 Requirements
The following table contains all requirements that are needed to meet the essential requirements as
defined in the Terminal Directive [1]. A justification according to article 4 of the Terminal Directive is given
by stating the relevant category (g) together with a text supporting the justification.
The entries are defined as follows:
- "ETS 300 607-1 Item" defines the item number of the conformance requirement and also the
reference to ETS 300 607-1 (GSM 11.10-1) [2]. This reference is a normative reference to a
subclause of ETS 300 607-1 (GSM 11.10-1) [2] containing the conformance requirement text, and
references to the base standard.
- "Description" contains a short description of the requirement.
- "TBR Justification" contains supplementary information to explain the justification of the requirement
according to article 4 of the Terminal Directive [1].
- "TD Cat" defines the category according to article 4 of the Terminal Directive [1].

- "Test Cat" defines whether the requirement is covered by a "special test situation" (e.g. a
manufacturer’s declaration of some form). An "X" indicates a special test situation, whilst, a blank
entry indicates conformity is by the test referred to by this TBR.
