3. Programming the Flag Bits
Controller features can be enabled of disabled with the use of the
Configuration Flag Bits. These bits are encoded into a single byte, which
is programmed into the controller at address 01. Multiple flag bits can be
selected by summing their hex weights. For instance, to set up a link
controller with no ISD1420, no courtesy tone, and suppress the DTMF
muting, you would add 01, 10, and 20 to produce hex 31, which you
would then program into address 01 in the controller as pppp0131.
