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 INACTIVE 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 default is 0.

2  –  INCREMENT

 Applies to DDCMP CONTROL circuits. This parameter sets the
 increment value added to the INACTIVE tributary priority each
 time the scheduling timer expires. Increment must be a decimal
 integer from 0 to 255.  If not specifically set, the default is 64.

3  –  THRESHOLD

 Applies to DDCMP CONTROL circuits.  It specifies the number of
 times to poll the active tributary before changing that
 tributary's polling state to inactive because of no data
 response.  Count must be a decimal integer in the range 0 to 255.
 The default count is 8.
