This clause includes seven test data sets; all are presented in hex, while the first is also presented in binary
Bit ordering should be largely self explanatory, but in particular:
The 5-bit BEARER is written in hex in a "right aligned" form, i.e. as a two-hex-digit value in the range 00 to 1F inclusive, with BEARER  as the msb of the first digit.
Similarly the single DIRECTION bit is written in hex in "right aligned" form, i.e. the DIRECTION bit is the lsb of the hex digit.
Where the length of the message, or of a message sub-block, is not a multiple of 32 bits, it is written in hex in a "left aligned" form, i.e. the least significant few bits of the last word will be zero.
