A default setting (95%) is provided, but there may be unique network configura-

tions which require modifying the STDMA Slot Capacity value.

STDMA Switch Delay

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 figure 3-43 to display the screen

shown in figure 3-45.

Percent Allocation

The Percent Allocation menu item, shown in figure 3-43, allows adding a fixed

percentage to the channel bandwidth request to accommodate additional band-

width requirements which may occur after a switch is made from STDMA to

SCPC mode.

To change this setting, enter E at the command prompt to display the screen

shown in figure 3-46.
