The Node ID number that appears in this screen verifies that the unit is regis-
tered with the VMS and is active in the network. This number is automatically
assigned by the VMS.
Note that the four Demods of the CDD-56X are designated as 0 through 3 on
this screen. The IF values represent the Intermediate Frequency (Hz) that this
unit is currently using. The AF values represent Adjusted Frequency (Hz), a
translation of the IF that is used by the VMS for internal tracking of switching
commands.
The DPC target entries are the IP addresses of the modulators that are to
receive the Dynamic Power Control messages from the Demods for this unit.
The Primary Heart Beat Interval represents the time period between the
communication check message that is sent from the primary Hub CDD-56X to
the VMS in an N:M redundancy configuration. This interval is specified in the
VMS.
Data for the Current Switch Cache reflects either the Home Satae information
immediately after the unit boots, or the last switch command from the VMS (the
last command sent to the base modem).
DPC details provide the status and E

o
values for active Remotes in the
group.
Vipersat Migration
The Vipersat Migration command is used to set the compatibility mode for the
Hub Burst Controller when conducting a firmware upgrade on the associated
Remotes. Although this command appears in the menu for both the Hub modem
and the Remote modem, it only applies to STDMA Controllers and TDM
Outbound modems at the Hub.
Enter M at the command prompt in the Vipersat Configuration screen to
display the Vipersat Migration dialog shown in figure 3-70.
Refer to the specific upgrade procedure that is to be implemented for instruc-
tions on whether/how to utilize this feature.
