Notes on Alphabets - Table 4-G
------------------------------
o ITA5 can be referred to as IRA
o ITA5 is the ASCII alphabet and consists of 128 characters, controls,
specials, numbers, lower case letters and upper case letters. This
is an 8 bit alphabet (sometimes includes a 9th bit for parity).
o ITA2P is 5 bit ITA2 converted to 7. A character is composed of
1 sync bit + 5 bit ITA2 char + parity. Sync bit is always 1 (except for
idle and RQ), parity is odd.
o BAUER is a 10 bit alphabet, used by AUTOSPEC and SPREAD
o 16 bit alphabet 0 is a 16 bit alphabet, used only by ROU-FEC
16 bit alphabet 1 is a 16 bit alphabet mod 10, used only by ROU-FEC
THESE ALPHABETS ARE LISTED IN Wavecom 4100 literature - no further details.
o These alphabets are based on ITA2, a 5 bit alphabet.

Notes:
o When using ITA-5 on 12 tone Piccolo the parity bit is ignored.
o The 6 tone Piccolo doesn't use the 3 lowest or the 3 highest
tones.
o Because of the way in which the Piccolo code was created the
6 tone Piccolo using ITA-2 is really a special case of the 12
tone Piccolo using ITA-5 but it is difficult to visualize here
so the 6 tone Piccolo table and the 12 tone Piccolo table are
presented as 2 tables. See the Klingenfuss RadioTeletype Code
Manual, 13th Edition for the table as designed.
