6–61
• 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.
• Excess Capacity (0 to 100) – Enter the Excess Capacity data rate percentage to be added to
the SCPC data rate. This setting makes additional bandwidth available for when demand
arises while minimizing Step Up switching events.
ToS Switching Configuration
• Enable – Use the drop-down list to select operation as Disabled or Enabled.
• Max # of Sessions (per ToS Id) (1 to 127) – Allows setting a limit for the number of active
sessions for a particular ToS switch type. Note that the overall limit for active sessions in the
network is 127.
