I have looked to one of supplement files there and I found notices
in TN5603 (see the end of file)

I have also tried to contact Adobe developers supoport:
-- First day I have been asked for my personal data.
-- Second day I have obtained human answer that I'm not registered (= paying)
   developer, so I must wait undefined time to answer.
-- Third day I have obtained answer from robot, that they are
   not help line for PostScript, because all can be found
   in PostScript Language Reference Manual.

I am adding test and info at the end of mail.

My last note about tiff2ps: Interpolate, in my opinion, should be optional.

       5 CCITTFax Filters

            CCITT stands for the Comité Consultatif International Télégraphique et 
            Téléphonique. This filter type, known as CCITTFaxEncode and 
            CCITTFaxDecode, is used for encoding and decoding facsimile (FAX) data 
            according to the CCITT standards. This filter is primarily intended for 
            encoding and decoding image data, not for communicating with FAX 
            machines.

    Note The CCITTFax filters accept an optional dictionary that includes the 
            CloseTarget key for the encode filters and the CloseSource key for the 
            decode filters.

            The implementation-defined limit for the value of the Columns key in the 
            decode dictionary has been increased from 25,000 to 62,000 for 
            LanguageLevel 3.
    Note There are C language source code files available for the CCITTFaxEncode 
            and CCITTFaxDecode filters. These files are readme.fax, makefile, bitstm.h, 
            ccmp.h, ccmpcode.h, ccmptab.h, cfaxfilt.h, protos.h, ccmpec.c, ccmpjc.c, 
            flipbyte.c, revbits.c, and runtab0.c. Although these files were written to 
            accompany an earlier level of the PostScript language, their information and 
            use should still apply. Source code can be acquired under license through the 
            Adobe Developers Association.

    Note For more information on the CCITTFaxEncode and CCITTFaxDecode 
            filters, see Section 3.3 of the Supplement: PostScript Language Reference 
            Manual, or Sections 3.8.4 and 3.13 of the PostScript Language Reference 
            Manual, Second Edition. See also Technical Note #5128, "PostScript Level 2 
            and Fax Modem Printing."
