SIST TBR 020 E2:2004

• Abstract:

  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, utilising 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: 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 ref rence. 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.

Overview

SIST TBR 020 E2:2004 is a Slovenian standard that aligns with European requirements for GSM mobile stations, specifically addressing telephony functionalities within the GSM900 band. Developed by SIST (Slovenian Institute for Standardization) and based on ETSI Technical Specifications, this standard details the essential technical and attachment requirements for terminal equipment connecting to public telecommunications networks in compliance with regulatory directives.

Adhering to the principles established in ETSI’s ETS 300 607-1 (GSM 11.10-1), the standard is pivotal for ensuring GSM mobile stations in the 900 MHz band meet necessary conformance and interoperability requirements for speech services, as per Phase 2 of the GSM digital cellular telecommunications system.

Key Topics

• Scope of Application

  • Defines technical and regulatory requirements for GSM mobile stations (MS) supporting telephony (speech) in the 900 MHz frequency range.
  • Applies to GSM900 equipment utilizing 200 kHz channel separation and Time Division Multiple Access (TDMA).
  • Covers only active accessories influencing terminal performance.

• Conformance and Approval Testing

  • Aligns with ETS 300 607-1 (GSM 11.10-1) for test purposes and conformance criteria.
  • Enumerates mandatory requirements for key speech transmission metrics, such as sending/receiving sensitivity, loudness rating, side tone masking, distortion, and acoustic coupling loss.
  • Outlines specific justifications for each regulatory requirement to meet the Terminal Directive 91/263/EEC.

• Functional Requirements

  • Addresses both full-rate and half-rate speech channels under dynamic and static operational modes.
  • Ensures requirements for transmission delay, speech transcoding, and Discontinuous Transmission (DTX) functions are met to guarantee network compatibility and satisfactory speech quality.

• Interoperability and Compliance

  • Facilitates interworking of mobile stations with public GSM networks, ensuring users experience reliable and intelligible telephony services.
  • Supplements other regulatory frameworks, with electromagnetic compatibility (EMC) addressed under separate standards and directives.

Applications

Implementing SIST TBR 020 E2:2004 is essential for manufacturers, network operators, and test laboratories who:

• Develop or Certify GSM Mobile Stations

  • Ensure devices intended for the European GSM900 market comply with key technical, functional, and regulatory requirements for voice services.

• Perform Regulatory Compliance Testing

  • Follow a clearly defined set of requirements and justifications for conformance assessment, including acceptance and approval within the European Union’s telecommunications market.

• Support Quality of Service (QoS)

  • Guarantee that GSM mobile stations provide high-quality telephony, free from undue distortion, delay, or network interworking issues.

• Facilitate Market Access

  • Achieve compliance with the Terminal Directive, fostering confidence among regulators and customers in the device’s network compatibility and speech performance.

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.
