SCPC Step Down Threshold

This menu item appears for the Remote modem 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.
Typically the default value will be optimum, 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 3-43. Note that this value must be less than the value specified for the
SCPC Step Up Threshold.

SCPC Step Delay

This menu item appears for the Remote modem only.
The SCPC Step Delay feature provides a switching delay period to ensure that
a premature switch up or down in the SCPC rate does not occur due to a tempo-
rary rise or fall in traffic.
A default value (in 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 3-44.
