4.3.1.9 MODEM SWITCHING STYLE
This screen allows the user to perform:
•
Linked Switching (U) - switching the modulator and demodulator together.
•
Independent Switching (M) - switching the modulator and demodulator separately.
When a prime channel is programmed for Linked Switching, both the modulator and the demodulator will
be switched to a backup channel if either the modulator or the demodulator fail. When a prime channel is
programmed for Independent Switching, only the modulator will be backed up if the modulator fails, and
only the demodulator will be backed up if the demodulator fails.
