4.28 CCITT O.33 Sequences EBU O.33 sequence
Although the LA102 cannot make measurements from a CCITT O.33 sequence (see
section 3.27), the LA101 can generate an O.33 sequence. This is achieved using the ‘–’
segment which takes 7 characters in quotes:
–"BBC1A01"
The first four characters are the source identification, the next character is the special
signalling character while the final two characters are the program identification (00-99).
The LA101 will generate an FSK header complying with the CCITT O.33 specification:
110 baud, 1 start bit, 7 data bits, 1 even parity bit and 2 stop bits (as for Lindos FSK),
with the following characters:
Start of header (SOH) character, ASCII 1
4 character source identification
Start of text (STX) character, ASCII 2
2 character programme identification
ETX (end of text) character, ASCII 3
Any CCITT O.33 sequence can be defined, by following this segment with tone (!) and
channel selection (:) segments.
EBU O.33 sequence
Although this header format is different from the Lindos header format, the LA102 will
display the characters from an O.33 header as they are received, providing it is in
sequence mode. This may be useful for identifying the source of an O.33 sequence, but
the LA102 will not make any measurements.
