Vipersat Configuration
3-48 Vipersat CDM-570/570L User Guide
Because this feature is configured in the VMS, the status (Disabled, or the Time
Period in minutes) appears as an information-only display in the Vipersat
Configuration menu (figure 3-6).
Dynamic Power Control Configuration
Dynamic Power Control (DPC) is a Vipersat feature that acts to regulate the
transmit power of the Vipersat satellite modem, such that the specified receive
signal level (Eb/No) is met for the receiving Vipersat units in the group. DPC is
driven by the receiver demod, which notifies the transmitting modem of the
current Eb/No value.
Refer to Appendix C, “Dynamic Power Control,” in this document for addi-
tional information on the DPC feature.
The Dynamic Power Control Configuration screen (enter C in the Vipersat
Configuration menu) allows for setting the parameters for the CDM-570/570L
power levels. The information and commands in the menu will vary depending
on the function that the target CDM-570/570L performs in the network. The
screen shown in figure 3-61 is for a Hub or Remote operating in STDMA mode.
For comparison, the DPC Config screen for a unit operating as a Hub or Remote
with Expansion (SCPC mode) is shown in figure 3-62. Note that only the appli-
cable settings appear in this screen.
