Vipersat Configuration
Figure 3-37 QoS Rules Based Switching screen
Determine which QoS rules will be used as a basis for performing SCPC
switching, then configure the VMS policy type, the SCPC switch rate, and the
timeout value to be associated with each rule. Assigning a 0 (zero) value means
that no SCPC switch will occur for that rule.
Enable QoS Switch Detection Feature
Once QoS has been enabled and configured as described above, the last step in
implementing QoS switching is to Enable the QoS Switch Detection feature.
Entering Q at the command prompt in figure 3-34 toggles the QoS Switch
Detection feature between Enabled and Disabled.
Load Switching
One of the four automatic switching functions that the Vipersat CDM-570/570L
is able to perform is Load Switching . The system will detect variations in data
rate and can be configured to switch from STDMA to SCPC based on band-
width requirements.
The initial switch for a Remote CDM-570/570L from STDMA mode to SCPC
mode is determined by the Hub Burst Controller. Once the Remote is switched
into SCPC, any requests to meet additional switching requirments within SCPC
(Step Up or Step Down) are made by the Remote modem.
The
Load Switching command on the Auto Switching menu is a toggle that
Enables and Disables Load Switching on the target CDM-570/570L. Entering
L at the command prompt will toggle between these two states. Refer to Appen-
dix B, Automatic Switching , in this document for additional information on
Load Switching.
