Vipersat Configuration

N:M redundancy (protected) configurations. The message interval can be speci- fied by the administrator through the VMS.

Enter P at the command prompt in the Vipersat Configuration screen (figure 3-5) to toggle this feature between Enabled and Disabled.

Home State Revert

This menu item appears for the Remote modem only.

The Home State Revert feature allows automatic resource recovery to be performed on SCPC connections when a communications failure occurs between the VMS and a Remote, such as a rain fade condition, a Remote unit power down, or a hardware failure. The period of time (in minutes) for a failure is configured in the VMS for each Remote in the network. Should communica- tions be lost for more than the specified time period, the Remote will automati- cally revert to its Home State settings and the VMS will remove all allocated resources (bandwidth, demod(s)), freeing them for use by any other Remote in the network.

Because this feature is configured in the VMS, the status (Enabled or Disabled) appears as an information-only display in the Vipersat Configuration menu (figure 3-5).

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 additional 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 3-51is 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 3-52.Note that only the appli- cable settings appear in this screen.
