SCPC Step Down Threshold
This menu item appears for Remote modems only.
The SCPC Step Down Threshold establishes the percentage of bandwidth use
that will trigger a switch down from the present SCPC rate to a lower rate to
ensure efficient bandwidth usage.
A default value (65%) is provided, but if a different threshold is desired, an
alternate value can be specified by entering D at the command prompt in the
Auto Switching screen to display the dialog shown in figure 3-52. Note that
this value must be less than the value specified for the SCPC Step Up Thresh-
old.

SCPC Step Up Delay
This menu item appears for Remote modems only.
The SCPC Step Up Delay feature provides a switching delay period to ensure
that a premature switch up in the SCPC rate does not occur due to a temporary
rise in traffic.
A default value (10 seconds) is provided, but this parameter can be modified by
entering W at the command prompt in the Auto Switching screen to display the
dialog shown in figure 3-53.
