Type identifier and cause of transmission assignments (station-specific parameters) are
shown in the following tables. In these tables, shaded boxes (░) are not required, black
boxes (█) are not permitted in the companion standard, empty cells indicate the functions
or ASDU are not used, and a cross (╳) indicates availability only in the standard direction.
