NOTE (1):
Quoted latencies are for back-to-back connected FWA units. For audio channels this is for audio
following channel initialisation. The total end-to-end latency will require addition of latency through the Radio Units.
Channel establishment is NOT included.
NOTE (2):
E & M latency includes a 5ms de-bounce delay.
NOTE (3):
For the UART the quoted delay does not account for the interface transmission delay (e.g. the
time to transfer a word between the connected UARTs at either end).
