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.
