Differentiates between the active, inactive and dying DDCMP timer
 parameters

1  –  BASE

 Applies to DDCMP CONTROL circuits. This value sets the base
 priority of an Dying tributary after the tributary has been
 polled.  You can set a separate base for each of the indicated
 polling states.  Base must be a decimal integer from 0 to 255.
 If not specifically set, the DYING BASE default is 0.

2  –  INCREMENT

 Applies to DDCMP CONTROL circuits. This parameter sets the
 increment value added to the DYING tributary priority each time
 the scheduling timer expires. Increment must be a decimal integer
 from 0 to 255.  If not specifically set, the DYING INCREMENT
 default is 16.

3  –  THRESHOLD

 Applies to DDCMP CONTROL circuits.  It specifies the number of
 times to poll the active or inactive tributary before changing
 that tributary's polling state to dying because of receive
 timeouts.  Count must be a decimal integer in the range 0 to 255.
 The default count is 2.
