Vipersat Configuration
For Dynamic Cycle and GIR configurations, the number of cycles is automati-
cally set to one in order to ensure optimum performance for these Hub types.
This parameter can be modified from the Hub CDM-570/570L by entering a C
at the command prompt as shown in figure 3-15.

On Remote units, this menu item is an information-only display.
Slot Guardband
This menu item, which appears for all Hub configurations, displays the current
length of the Slot Guardband in milliseconds and in bytes for the remotes in the
group. The Slot Guardband is the amount of time between the point when one
remote completes transmitting data and the point when the next remote in the
cycle begins transmitting. This prevents the remote from overrunning the next
terminal in the cycle. The setting for this parameter should be obtained using the
Vipersat STDMA Calculator.
Tip: For a copy of the latest Viper Calculator, contact a Comtech Vipersat
Networks representative.
On a Hub unit, this value can be modified by entering G at the command
prompt to display the dialog shown in figure 3-16 and entering a new value.

On Remote units, this menu item is an information-only display.
Note: The value entered at the command line in figure 3-16 is in milliseconds.
The corresponding value expressed in bytes is calculated by the
CDM-570/570L based on the STDMA transmit bit rate as shown in the
menu in figure 3-7.
