Tip: Contact either the network administrator or Comtech Vipersat Networks
Customer Support to obtain the Feature codes. A convenient option is to
use the Vipersat Vload utility to manage Feature codes.
Vipersat Management
This item is an information-only display, and indicates whether Vipersat
Management is Enabled or Disabled in the target CDD-56X. Activation of the
Vipersat Feature Code automatically enables the Vipersat Management feature.
Caution: This command must be Enabled in order to utilize any of the Vipersat
capabilities of the CDD-56X.
Vipersat STDMA
In order to utilize the Vipersat STDMA feature (burst mode) in the target
Vipersat CDD-56X, this feature must be Enabled. Enter A at the command
prompt to toggle On or Off.
Refer to table 2-2 for the relationship between Unit Role and STDMA. This
feature should only be enabled for a unit that is used as a Hub with no expansion
(i.e., a Burst Controller).
Note: Although the CDD-56X has multiple demods, STDMA is configurable for
only one demod. When this parameter is enabled, Demod 1 is set for
STDMA mode and the remaining demods are set for SCPC mode.
Vipersat Auto Switching
The Vipersat Auto Switching feature allows the CDD-56X to automatically
adjust to varying bandwidth demands in the Vipersat network by switching
between STDMA and SCPC connections. This feature should only be enabled
for a unit that is used as a Hub with no expansion, and that will be required to
send switching requests to the VMS in response to either traffic type (Applica-
tion switching) or network traffic loads (Load switching). Refer to table 2-2 for
the relationship between Unit Role and Auto Switching.
