latter is not also faulted. If there is no fault, the backup holdoff
determines how long the switch will wait before performing the
actual backup, or switchover of traffic to the redundant modem.
When the switch is currently backing up a traffic modem, and
that offline modem’s fault clears, the switch will continue to
back it up unless another active modem becomes faulted. In this
case, the restore holdoff is the length of time that the originally
faulted modem must stay unfaulted before the switch will
automatically put it back online so that the redundant modem
is available to bridge the newly faulted modem. Both holdoffs
can be set from 2 to 99 seconds.

ALARM MASK
The switch logs and reacts to both modem faults and its own
faults. Types of either may be masked using this sub-menu. In
addition, an audible buzzer can be enabled as an additional
indicator.
(CONFIG, OPTS, MASK)
MODEM ALARMS
The user is prompted to mask Transmit or Receive Traffic
faults (or both) from being reacted to by the switch. This
not only prevents the switch from performing Auto mode
functions when these modem faults are sensed, but also
keeps the faults from being logged by the switch. Note
that these selections are global to all the modems. If
masking of individual modem faults is desired, it should
be done directly on the modem. Unmasked modem
faults are logged on both active and inactive modems.
