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.
