NOTE
Before enabling DPC, the operator should verify that a demodulator at another
terminal is receiving from this modulator, and that there is a working communi-
cations channel from that receiving station back to the modulator terminal
(inband communications). Additionally, since DPC controls potentially the full
power range of the modulator's output power, it is recommended that the termi-
nal be commissioned and calibrated before usage.
Tip: The DPC feature will not function unless the Outbound IP address is

DPC Enabled

The DPC Enabled command (enter E) is a toggle that allows the DPC feature
to be either Enabled or Disabled. The CDM-570/570L is shipped with the DPC
Enabled menu item turned off (Disabled) to allow entrance link levels calibra-
tion during terminal setup.

Calibrated Data Rate

This menu item is for information only and displays the Calibrated Data Rate
in Kbps for the target CDM-570/570L. This value is pulled from the Home
State.
There is a proportional relationship between data rate and power level; as the
data rate increases, there is a corresponding increase in transmit power level,
and vice versa.
