6.2.28. Continuous Wave Identification
This block periodically inserts a Morse code identifier into an audio stream. It has one input
and one output. The input is the audio stream into which the identifier is to be inserted.
The output is the audio stream, with the identifier inserted. The period between identifiers,
the speed of the Morse Code, the frequency of the CW tone and the message being sent are
set in the transmitter profile, on a per channel basis. Further details are in section 7.10.
The CWID block will only insert audio when the incoming audio stream is inactive, meaning
the identifier will never interrupt a call. If the audio is active when the next identifier is due,
the identifier will be sent at the first opportunity, after the audio becomes idle. If the
transmission of an identifier is interrupted by a call, it will be retransmitted at the first
opportunity, until it has been sent in its entirety.
If the identifier is to be override a call, leave the input to the CWID block disconnected, and
use either a priority or addition block to mix the output of the CWID block into the audio
stream.
The CWID Block uses the International Morse Code, as in
Table 1.

6.2.29. Digital Input/Output
This block generates a verbal announcement in response to an external digital input. It has a
single output, which is active whenever the alarm message is being spoken. The message
