The available memory
threshold, below which ringing
detection (and therefore
reception into memory) is
disabled
00 to FF (Hex), unit = 4 kbytes
(e.g., 06(H) = 24 kbytes)
One page is about 24 kbytes.
The machine refers to this setting before each fax
reception. If the amount of remaining memory is
below this threshold, the machine cannot receive
any fax messages.
If this setting is kept at 0, the machine will detect
ringing signals and go into receive mode even if
there is no memory available. This will result in
communication failure.
