Vipersat Configuration
3-30 Vipersat CDM-570/570L User Guide
Note: Load Switching must be enabled for each CDM-570/570L in a
network that is going to perform Load Switching in order for the
VMS to dynamically optimize network performance as load condi-
tions change on these circuits.
Application switching by the VMS, such as for Voice and/or
Video, is not affected by this setting. However, using Load
Switching for real-time applications is not recommended.
STDMA Slot Capacity
This menu item appears for Hub modems only.
The STDMA Slot Capacity command allows setting the threshold or level of
slot capacity at which the Burst Controller sends a switch request to the VMS to
switch the Remote from STDMA mode to SCPC mode.
Typically the default settings will be optimum, but there may be unique network
configurations that require modifying the STDMA slot capacity value. To
change this setting, enter U at the command prompt in figure 3-33 to display the
screen shown in figure 3-38.

STDMA Switch Delay
This menu item appears for Hub modems only.
In order to minimize unnecessary switching from STDMA to SCPC due to tran-
sient conditions, such as a temporary spike in network traffic for example, a
switch delay parameter is provided.
Typically the default values will be optimum, but this value can be changed to
accommodate a unique network configuration or application. To change this
setting, enter W at the command prompt in figure 3-33 to display the screen
shown in figure 3-39.
