Figure 3-61 Target DPC Address prompt
The STDMA Burst Controller (Demod 1 on a CDD-56X configured as Hub
with No Expansion) is not permitted to specify a DPC Target because the
demodulator is receiving multiple bursts very rapidly from all Remotes in the
group and is unable to utilize DPC to control the transmit power of the Remote
modems. However, the transmit power of the Burst Controller adjusts to meet
the target E

values for the Remotes in the group. These Remotes and their
status and E

/N
o
values are displayed in the Vipersat Summary screen, DPC
details (see “Vipersat Summary” on page 3-51).
Set Home State Parameters
A CDD-56X’s Home State consists of those parameters which provide a
known RF configuration that the CDD-56X will return to, either as the result of
a command by the VMS, or as it comes back on line from a reset or a power
cycle.
Enter H at the command prompt in the Vipersat Configuration screen to
display the Home State Configuration screen shown in figure 3-62.
A CDD-56X’s Home State settings are typically selected so that it goes to a
configuration which is optimum for its function in the network. These parame-
ters are configured on an individual, per demod basis.
Note that each of these Receive parameters are the same as found in the Rx
Configuration screen that is in the Satellite Demod Configuration menu.
