These
holdoffs
are
only
applicable
when
the
Switch
is
in
Auto
Mode.
When
an
active
modem
exhibits
an
unmasked
fault,
the
Switch
checks
that
the
Redundant
Modem
is
not
also
faulted.
If
there
is
no
fault,
the
Backup
Holdoff
determines
how
long
the

is
currently
backing
up
a
Traffic
Modem,
and
that
offline
modem’s
fault
clears,
the
Switch
will
continue
to
back
it
up
unless
the
active
modem
becomes
faulted.
