Notes:

1For subparameter VR, values 00, 01, 02, 04, 08, 10, 20 and 40 (hexadecimal) indicate a single choice; they are the only values allowed in the +FCS parameter and +FCS: report. All values that are sums of these values shall only be used to indicate multiple capabilities; these are allowed in +FIS and +FCC parameters. For example, value 07 (01 + 02 + 04) would indicate capability for all metric-based resolutions.

2For subparameter JP, values 00, 01, 02, 04 08, 10, 20 and 40 (hexadecimal) indicate a single choice. All values that are sums of these values shall only be used to indicate multiple capabilities in +FIS and +FCC subparameters and to indicate the choice in the +FCS subparameter. For example, to indicate support for JPEG, full color mode ,and no subsampling, the host should set the JP subparameter to 01 + 02 + 10 = 13h. If one or several of the values 02h to 40h are not used, that means that the default value for the subparameter (e.g. respectively: gray-scale, custom Huffman tables, 8 bit/pel/component, 4:1:1 subsampling ratio, D50 illuminant, default gamut range) is used, as defined in Annex E/T.30 and Annex G/T.4.

3The modem ignores this value in •FCC and in •FIS when generating DIS or DTC frames.
