10.5.11.2 DS3 M23 (with C-bits used as payload) Direct Mapping
For direct mapping into DS3 M23 (with the C-bits used as payload) frames, ATM cells must be bit aligned, HDLC
packets are always bit aligned. The NAD bit must be set to one in this mode when direct mapping ATM cells into
DS3 M23 (with the C-bits used as payload) frames.
NOTE: PLCP mapping into DS3 M23 (with the C-bits used as payload) frames will not operate correctly.
