Overview

SIST ETS 300 242:2003/A1 E1:2003 provides essential amendments to the European telecommunications standard for Terminal Equipment (TE) focusing on Group 3 facsimile equipment. Developed by the Slovenian Institute for Standardization (SIST) and aligned with the European Telecommunications Standards Institute (ETSI), this standard refines testing procedures for facsimile (fax) devices, particularly clarifying test combinations and introducing new requirements for Error Correction Mode (ECM) as standardized by CCITT Recommendation T.30.

This amendment is critical for manufacturers and testing bodies engaged in the development, testing, and certification of Group 3 facsimile equipment, ensuring conformance, compatibility, and efficiency in the telecommunications sector.

Key Topics

• Group 3 Facsimile Equipment: Focuses on equipment classified under ITU-T Group 3, widely used in analog fax transmission.
• Error Correction Mode (ECM): Details test requirements for equipment offering ECM, an optional feature enhancing data integrity during fax transmission.
• Testing Procedures: Specifies the combination and execution of tests for both normal and exceptional operating conditions. Emphasizes efficient test sequencing where validity is maintained.
• Conformance Requirements: Introduces new test cases (B.7) for ECM-capable devices, aligning with CCITT T.30.
• Coding Definitions: Adds precise DIS/DTC and DCS coding table data for use in relevant test cases.

Applications

• Product Development: Assists designers and manufacturers of Group 3 fax devices in meeting updated regulatory and technical requirements, supporting market access and compliance in Europe and internationally.
• Testing and Certification: Enables standardized and efficient testing of facsimile equipment for both normal and exceptional scenarios, particularly for devices implementing ECM.
• Quality Assurance: Promotes robust error management and data integrity in fax communications, minimizing transmission errors and ensuring reliable operation.
• Regulatory Compliance: Ensures terminal equipment meets both national (Slovenian) and pan-European telecommunications standards, supporting harmonization across markets.

Related Standards

Understanding and applying SIST ETS 300 242:2003/A1 E1:2003 is enhanced by familiarity with these related documents:

• ETS 300 242 (1992): The original European standard for Terminal Equipment, Group 3 facsimile equipment.
• CCITT Recommendation T.30: International foundational standard defining procedures for Group 3 facsimile communication, including ECM.
• EN 300 242: European Norm version providing harmonized requirements for fax terminal equipment.
• IEC and ITU-T Standards (e.g., V.21, V.27ter): These support lower-level and protocol-specific requirements for facsimile communication, including signaling and modulation.

Practical Value

Integrating the amendments in SIST ETS 300 242:2003/A1 E1:2003 into the product lifecycle improves interoperability, test efficiency, and adherence to international best practices. Companies benefit from reduced non-compliance risks, streamlined test procedures, and assurance that their Group 3 facsimile equipment will function reliably in global markets.

Effective implementation of this standard supports ongoing improvements in fax technology, ensuring that error correction and testing align with evolving communication needs and regulatory landscapes.

Foreword
This Amendment to ETS 300 242 (1992) has been produced by the Terminal Equipment (TE) Technical
Committee of the European Telecommunications Standards Institute (ETSI).
This Amendment to ETS 300 242 covers changes to tests in Annex B - Testing. The changes are to
include clarification regarding the possibility of combining tests for efficiency and also to include a new
Clause (B.7) covering the CCITT standardized Error Correction Mode (ECM).
ECM is an optional feature of a facsimile equipment. For equipment providing ECM, conformance to this
ETS will include tests defined in Clause B.7 (see below).
For equipment not providing ECM, conformance testing to this ETS does not include tests defined in
Clause B.7 (see below).
Amendments
The changes covering the combination of tests are as follows:
Page 14, subclause B.1.3 insert the following text at the start of the 4th paragraph.
"For efficiency in testing, a test sequence may combine any number of tests where the combination does
not affect its validity".
Page 15, subclause B.1.4.1 add the following sentence at the end of the text.
"However, for efficiency, tests may be combined".
Insert the following text as Clause B.7 to Annex B.
"B.7 Tests for CCITT Recommendation T.30 in ECM mode
B.7.1 Tests for normal conditions
B.7.1.1 Test No. TNO1 . TNO9
Testing normal conditions with ECM capability.
Facsimile equipment transmitting/tester receiving.
Facsimile equipment transmits two test charts: first a CCITT Test Chart No.3 followed by an all white page
not exceeding A4 length.
Before each sequence a call is established and the tester shall:
T-DIS V2;
R-DCS;
R-phasing/training, TCF;
T-CFR;
R-fax msg in ECM mode.
For facsimile equipment capable of transmitting only one page, tests TNO4, TNO5 and TNO6 shall not be
applied.
NOTE 1: Optional signals may appear before DCS.
NOTE 2: Tests TNO1-TNO3 may be repeated several times, depending on the number of bytes
per frame selected in the DCS frame.
