APPENDIX I
(to Recommendation T.101)
Text and mosaic character repertoires
	In the Interworking Data Syntax all text and mosaic characters are assigned a code name so that they may be uniquely identified. An exhaustive Repertoire of all of the text and mosaic characters used in the data syntaxes specified in Recommendation T.101 is presented below. This simplifies many of the references to graphic character sets used in the IDS since only the code names need be used in the body of the ASN.1 description of the Interworking Data Syntax. None of the videotex data syntaxes make use of all of the text and mosaic characters identified below. There are areas where there is a large amount of overlap between the various data syntaxes. In order to aid transcoding and conversions several categories have been identified. Separate repertoires have been defined for each of these categories.
I.1	Repertoire I – Common alphanumeric text characters
	Repertoire I contains the common repertoire of basic alphanumeric text characters. These characters are taken from the primary and supplementary characters from Recommendation T.51, with registered final characters 4/0 and 6/2 respectively. In addition this includes the SPACE character (SP01) and the DELETE character (SM34). The descriptive names given to characters differ between the various terminal data syntaxes defined in Recommendation T.101 and between the repertoire of alphanumeric characters defined in ISO standards ISO 6937. Composite names are used here, which endeavour to include the full range of meanings specified in the different terminal data syntaxes identified in Recommendation T.101, and achieve the maximum level of commonality with ISO 6937.

	Note – The characters SM43, SM44, SM47, SM48 have multiple names since the descriptive names for these characters differ significantly between the various terminal data syntaxes defined in Recommendation T.101. These characters were originally intended as accent characters in the original usage of the IRV code table of ISO 646. This meaning has changed since the introduction of the composite method of coding accented characters defined in CCITT Recommendation T.51, ISO 6937 and several CCITT Recommendations. As a result these characters should not be used to generated accented characters. To retain compatibility with previous standards, multiple names are described here.

	Note – Since name codes are not included for these characters in either the ISO registry (Registration number 13) or in CCITT Recommendation T.101, codes beginning with JA are introduced here.
I.4	Repertoire 4 – Kanji characters
	These characters occur in only one of the terminal data syntaxes although the registered Kanji character code table is sometimes used in combination with the sets of another terminal data syntax. Except in the case when Kanji character capability is available at both ends of an interchange, the presentation of these characters must be converted so that their presentation effect may be achieved in the other terminal data syntax. The Kanji character set is registered as a two byte set. CCITT Recommendation T.101 uses a sub–Repertoire of this set which includes some 3639 characters, of which 2980 are Kanji symbol characters. These characters are unique to this Repertoire. The remaining characters, including a number of special characters as well as some alphabetics for other languages, overlap with other registered character sets. For example a Cyrillic, Greek, Katakana, and Hiragana alphabet are included, as well as all but 11 of the Latin alphabet characters of Repertoire 1. The overlap characters in this code table have the same name codes as the equivalent characters in Repertoire 1 and can therefore be converted directly between data syntaxes. Special handling is required for the other characters. In addition there are 32 drawing characters which overlap those in Repertoire 8. These also share the same name codes as those in other character sets and therefore are part of the greater drawing character Repertoire (Repertoire 8).
	The Repertoire of Kanji pictorial characters and unique special characters is voluminous. Since conversions from this Repertoire of characters require special handling, it is not necessary to list the Repertoire here. For reference, see CCITT Recommendation T.101 Data Syntax I which is a sub Repertoire of the ISO registration number 87. The name codes Kanji JK01 to JK2980, HK01 to HK83, and JS01 to JS366 have been introduced to identify the Kanji pictorial characters, the Hiragana characters, and the Kanji Special characters respectively.

I.7	Repertoire 7 – Block mosaic characters
	Block mosaic characters are a sub–Repertoire of the mosaics used in each of the terminal data syntaxes and therefore are directly translatable between data syntaxes. Even the coding of the block mosaic characters is identical except for the Filled Mosaic character. A Filled Mosaic is included in Repertoire 5. Either of the two equivalent codings established in Recommendation T.101 (code table position 5/15 or 7/15) for the Filled Mosaic character is acceptable in a string of characters from Repertoire 5.
	Note – The following convention is used to describe the shape of a 2 sub–cell wide by 3 sub–cell high mosaic character. The cells are numbered from the upper left, to upper right, centre left, centre right, lower left, and lower right as 1,2,3,4,5,6 respectively. This code is used in identifying each character in the Repertoire.

I.8	Repertoire 8 – Sub cell aligned smooth mosaics 1
	A general set of Sub Cell Aligned Smooth Mosaic characters are part of the Repertoire of mosaic characters used in two of the terminal data syntaxes, and have the same coding. These characters are identified separately as a Repertoire of the interworking data syntax since these characters are directly translatable between two of the data syntaxes. The presentation of these characters must be converted so that their presentation effect may be achieved in a terminal using a data syntax which does not support these characters.
	Note – The following convention is used to describe the shape of a 2 sub–cell wide by 3 sub–cell high mosaic character containing Sub Cell Aligned Smooth Mosaics. The vertices of the sub–cells are numbered from the upper sub–cell upper left corner as illustrated below. The smooth mosaic is filled below (B), above (A) to the right (R) or the left (L) of a line or lines through the indicated vertices.

I.9	Repertoire 9 – General smooth mosaics
	An additional form of Smooth Mosaic characters are available in only one of the terminal data syntaxes. These smooth mosaic characters align with half sub–cell boundaries. Since these characters are unique to only one of the terminal data syntaxes, the presentation of these characters must be converted so that their presentation may be achieved in another terminal data syntax.
	Note – The notation used to describe these characters is the same as that used in Repertoire 6 except that intermediate points which identify to the half sub cell are introduced. In the case that four numbers are given, such as for the characters (SG58 and SG71), the area is bounded on all sides by the four sub–cell positions. In two special cases, for the characters (SG68 and SG81), two areas are filled within the mosaic cell.

I.10	Repertoire 10 – Drawing characters
	A number of drawing characters, consisting primarily of line drawing characters are available in the various terminal data syntaxes. These consist of the drawing characters (DG01 to DG04, DG13 to 24, and DG32) which are common between DS I and DS II of CCITT Recommendation T.101, drawing characters (DG35 to DG50) which are unique to DS 1, drawing characters (DG05 to DG12, and DG25 to 31) which are unique to DS II and drawing characters (DG33 and DG34) which are unique to DS III.
	Note – The notation used to describe these characters identifies the character sub–cell vertices and intermediate points in a similar manner to the way smooth mosaics are identified in Repertoire 7; however, only lines are used here to connect the vertex and intermediate points. Some of the drawing graphics contain more than one line component. This is identified by the description of two line elements separated by “&”. In addition, the line weight (or width) may vary on some drawing characters. Heavy weight (wider) line elements are indicated by (W). Special drawing graphics are described in words.

APPENDIX II
(to Recommendation T.101)
Default states of the interworking data syntax
	The Interworking Data Syntax permits a choice of the default states to be established. These defaults correspond to the default states of the terminal oriented data syntaxes corresponding to the source of the data. Referencing Tables II–1/T.101 to II–3/T.101 provides a convenient way of establishing the states required for interworking with a particular source of data. Only three default tables are described below. If a particular profile of a data syntax does not correspond exactly to the default table given below, then explicit state vector commands may be used to alter the particular states which are different.
	The default tables include the default values for the function and parameters of the data syntax as well as the default boundary conditions. The Terminal Model Precedence indicator is always assumed to be initially “1”, and of course at the initial point, or at a reset, all global variables are assumed to be altered.
	Note – In Tables II–2/T.101 below a question mark “(?)” implies that the information for that entry in the table needs to be confirmed. A question mark alone indicates that the information needs to be supplied in a future version of the document.
