32、e 9 ETS 300 242: May 1997 5 Technical characteristics 5.1 General The facsimile equipment shall comply with the requirements of ITU-T Recommendation T.4 2, paragraphs 1, 2, 3, 4, 5, 6, 7, 8 and ITU-T Recommendation T.30 3, paragraphs 1, 2, 3, 4.3, 5, and additional requirements as described in this
33、ETS. The facsimile equipment may also include the optional error correction mode described in ITU-T Recommendation T.30 3, annex A. The testing specification is given in annex B. Requirements for the scanner of the facsimile equipment based on test chart No. 4 of ITU-T Recommendation T.22 4, are con
34、tained in annex A. This applies only if a physical scanner is implemented. 5.2 Features Basic feature: A standardized feature which is mandatory for the certificate of conformity. Optional feature: A standardized feature of facsimile equipment which may be used in a specified way to supplement the b
35、asic features and which incorporates compatibility between facsimile equipment. Optional features in this ETS are not mandatory but when implemented shall be implemented as described in this ETS for the certificate of conformity. The applicant shall state which optional features are to be certified.
36、 Special feature: A non-standardized feature of facsimile equipment which can be used to supplement basic or optional features but which does not incorporate compatibility between facsimile equipment. A special feature shall not impair the compatibility of basic or optional features between facsimil
37、e equipment. 5.3 Transmitter For equipment which is capable of sending only A5 and/or A6 size documents, the requirements for equipment capable of sending A4 size documents shall not be applied. 5.3.1 Document dimensions The facsimile equipment shall be capable of accepting and scanning documents wi
38、th dimensions of at least 212 mm x 299 mm. 5.3.2 Scanning track The density of picture elements (pei)s along the scanned line shall be between 7,79 pel/mm (200 pels/25,4 mm -1 %) and 8,12 pel/mm (1 728 pels/215 mm +1 Yo). The basic scanned line contains 1 728 pels. This length is thus between 1 728/
39、7,79 = 221,8 mm and 1 728/8,12 = 212,8 mm. For implementations which use centre alignment of the document in the scanner, the reference position of the document shall be such that the centre of the document lies between picture elements 851 and 877 over the first 20 mm of the document. For implement
40、ations which use right edge alignment of the document in the scanner, the reference position of the document shall be such that a point 10 mm from the right edge of the document lies between picture elements 1 623 and 1 648 over the first 20 mm of the document. The applicant shall state which implem
41、entation has been used. In addition to the basic line length, other lengths may be implemented. The basic scanning density shall be between 3,81 line/mm (3,85 line/mm -1 %) and 3,98 line/mm (100 line/25,4 mm +1 “/O). In addition, the facsimile equipment may provide other scanning densities. The sele
42、ction of the one used for message transmission shall be controlled by the transmitting equipment. STD-ETSI ETS 300 242-ENGL 1777 3400855 019bb08 O71 Page 10 ETS 300 242: May 1997 The document shall be positioned such that the first line to be coded and transmitted lies between O mm and 4 mm down the
43、 document from the top edge if the facsimile equipment does not transmit information related to its identity as part of the image signal. If the facsimile equipment does transmit information related to its identity as part of the image signal, then the first line to be coded and transmitted lies bet
44、ween O mm and 14 mm down the document from the top edge. 5.4 Receiver For equipment which is capable of receiving only A5 and/or A6 size documents, the requirements for equipment capable of receiving A4 size documents shall not be applied. The decoded picture elements shall be recorded as if the sca
45、nning direction was from left to right with subsequent recording lines adjacent to and below the previous line. The direction of recording refers to viewing the received copy in the vertical plane. The density of picture elements along the recorded line shall be between 7,79 pel/mm and 8,12 pel/mm.
46、The effective minimum recorded line length shall be 200 mm. For implementations which use centre alignment in the printer, the reference position of the recording medium shall be such that the centre of the recording medium lies between picture elements 851 and 877 over the first 20 mm of the docume
47、nt. For implementations which use right edge alignment in the printer, the reference position of the recording medium shall be such that a point 10 mm from the right edge of the recording medium lies between picture elements 1 623 and 1 648 over the first 20 mm of the document. The applicant shall s
48、tate which implementation has been used. In the case of facsimile equipment limited to A4 length received copies, the position of the recording medium shall be such that the first line to be recorded lies between O mm and 5 mm down the received copy from the top edge. 5.5 Performance The performance
49、 of the facsimile equipment shall be evaluated using the ITU-T Facsimile Test Chart No. 4 detailed in ITU-T Recommendation T.22 4. Performance tests of the facsimile equipment are described in annex A of this ETS. 5.6 Control procedures for message transmission and reception The facsimile equipment shall follow the binary coded control procedures detailed in ITU-T Recommendation T.30 3. As a basic feature, the facsimile equipment should transmit the appropriate subscriber identification signal Called Subscriber Identification (CSI)/Calling Subscriber Id
