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.
A default setting (95%) is provided, but there may be unique network configura-
tions that require modifying the STDMA slot capacity value. To change this
setting, enter U at the command prompt in the Auto Switching screen to display
the dialog shown in figure 3-48.

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. This setting is used to specify a delay before
a switch occurs.
A default value (10 seconds) is provided, 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 the Auto Switching screen to
display the dialog shown in figure 3-49.
