The valid operating ranges for items in this section are provided in parentheses.
•
Mode – Use the drop-down list to select operation as Disabled or Enabled.
Click [Submit] to save.
• Step Up Threshold (0 to 100) – Enter the percentage of bandwidth use that will trigger a
switch up from the present SCPC rate to a higher rate to ensure that there is sufficient
bandwidth available for current conditions. Note that this value must be greater than the
value specified for the SCPC Step Down Threshold. A typical setting for this parameter is
95%.
• Step Down Threshold (0 to 100) – Enter 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
for current conditions. Note that this value must be less than the value specified for the
SCPC Step Up Threshold. A typical setting for this parameter is 65%.
•
Delay (1 to 50) – Enter the Switching Delay period, in seconds, to ensure that a premature
switch up or down in the SCPC rate does not occur due to a temporary rise or fall in traffic.
