SIST ETS 300 280 E1:2003 is a SIST publication that is identical to ETS 300 280 Edition 1 from ETSI. It specifies terminal tests for Terminal Equipment (TE) offering Facsimile group 4 class 1 functionality on the Integrated Services Digital Network (ISDN). The document is for laboratories, manufacturers, and reviewers who need to check whether a terminal’s reception, printing, scanning, and related operating functions behave as required.
What does SIST ETS 300 280 E1:2003 specify?
SIST ETS 300 280 E1:2003 specifies the terminal tests for equipment that offers Group 4, class 1 facsimile functionality on ISDN. In practice, it is the test companion to the functional and protocol standards that define how this kind of fax terminal should work.
The document is organized as a test specification with supporting annexes. The main clauses cover scope, normative references, definitions and abbreviations, the coding algorithm test, printing tests, scanning tests, miscellaneous tests, and testing conditions.
| Annex | What it covers |
|---|---|
| Annex A | Normative definition of the T6test chart |
| Annex B | Normative definition of the PFTEST chart |
| Annex C | Informative explanation of the Guaranteed Reception Area |
| Annex D | Normative PICS proforma for terminal testing of the B-channels part |
| Annex E | Informative bibliography |
What are the key requirements of SIST ETS 300 280 E1:2003?
SIST ETS 300 280 E1:2003 is built around practical test cases for reception, printing, scanning, and operating behavior. The key point is that the standard does not just describe functions - it tells the tester what to send, what to inspect, and what to verify on the system under test (SUT).
Coding algorithm and reception
Clause 4 uses the T6test electronic chart from Annex A to check the Group 4 coding algorithm on reception. The tester transmits the chart and the SUT must display an image with the expected boundary behavior and correctly represented marked areas.
For a reader, this means the terminal’s basic decoding path has to preserve the structure of received facsimile images. It is a direct check that image data can be received and reconstructed in a usable form.
Printing functions
Clause 5 tests printing behavior using PFTEST from Annex B. The tests cover image orientation, page orientation, guaranteed reception area, resolution, paper positioning, and general printing capability.
In practice, this is where a supplier confirms that the received page prints the right way round, in the right place on ISO A4 paper, and with the expected printable area. The clause also checks handling of the Call Identification Line (CIL) relative to the guaranteed reception area.
Scanning tests
Clause 6 checks how the SUT scans and transmits using CCITT Recommendation T.21 test chart number 3. The tests cover basic scanned line length, scanning density, and the position of the document.
Table 4 then interprets several zones of the test chart to judge line reproduction, line separation, resolution limits, and distortion. For a manufacturer, this section is important because it verifies that the scanner preserves geometry and detail before transmission.
Miscellaneous operating tests
Clause 7 covers several operating behaviors that matter in day-to-day use. These include automatic answering, user-selected CIL placement, CIL format according to CCITT Recommendations F.184 and F.200, maximum receiving time, recovery after a power failure, date and time handling, and an activity log if one is provided.
These checks matter because they show how the terminal behaves around the core fax functions. They are the kind of details that affect installation, user experience, and fault handling.
Test conditions
Clause 8 sets the environment and power-supply conditions for the tests. The test results are intended to be taken only under declared operating conditions for the equipment.
This is practical guidance for laboratories and buyers: results should be interpreted in the same environmental and supply conditions that the supplier declares for the product.
Conformance reporting
Annex D adds a Protocol Implementation Conformance Statement (PICS) proforma for the B-channels part of ISDN facsimile Group 4 class 1 equipment in basic access and circuit-switched mode. The tables separate terminal class and configuration, main capabilities, optional capabilities, and indicators.
That means the supplier has a structured way to state what the implementation supports before testing begins, which helps labs scope the test effort and compare implementations consistently.
What terms does SIST ETS 300 280 E1:2003 define?
Call Identification Line (CIL) is the line printed on the page that carries call-identification information, and the standard checks where it is printed relative to the reproducible area.
Protocol Implementation Conformance Statement (PICS) is the completed statement of which protocol capabilities and options are implemented for a given product.
Protocol Implementation eXtra Information for Testing (PIXIT) is the extra implementation and test-environment information that the test laboratory needs alongside the PICS.
System Under Test (SUT) is the terminal being evaluated during the test.
Picture Element (PEL) is the image unit used to express resolution and image dimensions in the tests.
Terminal Identification (TID) is the identification information handled and printed by the terminal, including insertion and format checks in the PICS tables.
Who uses SIST ETS 300 280 E1:2003?
SIST ETS 300 280 E1:2003 is used by test laboratories, terminal manufacturers, and conformance engineers who need to verify fax terminal behavior against a defined test suite. Quality managers and buyers can also use it to ask for evidence that a terminal has been tested for the required reception, printing, scanning, and operating functions.
It is especially relevant for teams working with ISDN facsimile Group 4 class 1 equipment and with the associated conformance reporting for PICS and PIXIT documentation.
What changed in SIST ETS 300 280 E1:2003 from the previous edition?
SIST ETS 300 280 E1:2003 is identical to ETS 300 280 Edition 1.
Which standards are used with SIST ETS 300 280 E1:2003?
SIST ETS 300 280 E1:2003 cites several companion standards and recommendations that define the functions being tested:
- ETS 300 080 - lower layer protocols for telematic terminals on ISDN
- ETS 300 087 - functional specification of the facsimile Group 4 class 1 equipment
- ETS 300 112 - end-to-end protocols
- prETS 300 155 - end-to-end protocol tests
- CCITT Recommendation T.6 - coding schemes and coding control functions
- CCITT Recommendation T.563 - terminal characteristics
- CCITT Recommendation T.21 - standardized test charts for document facsimile transmissions
- CCITT Recommendation F.184 and F.200 - CIL-related service and format provisions
- CCITT Recommendation T.433 - negotiation and indication mechanism for document transfer
- CCITT Recommendations T.521 and T.503 - application profile references used in the normative references
These references give the technical basis for the test cases, the charts, and the conformance reporting used in the document.
What does the SIST ETS 300 280 E1:2003 document contain?
SIST ETS 300 280 E1:2003 contains test tables, chart definitions, explanatory figures, and a conformance proforma. The body of the standard includes test sequences for reception, printing, scanning, and miscellaneous checks, while Annex A and Annex B define the electronic test charts in formal detail for several resolution levels.
Annex C explains the Guaranteed Reception Area and how the tested printable area relates to an ISO A4 page. Annex D provides the PICS tables and guidance for filling them in, and Annex E lists bibliography items used for background and methodology.
The document therefore serves as a practical test specification, not just a functional description.
