Comtech EF Data VMS v3.12.x Vipersat - Manual (Page 385)

Chapter 7 - Out-of-Band Units 7-29
MN/22156, rev 12 Switching Out-of-Band Modems
The VMS uses the reference power setting as a basis for calculating the
correct power level for the carrier when setting up a switch event. This value
must be sufficient to close the link to the weakest receiving site.
8. If a priority setting is applicable for this circuit, click on the Priority check
box to activate this field (checked) and enter the required level.
Note that a lower number corresponds to a higher priority level. The default
value (0) equates to No priority.
9. For modem units that are Vipersat-enabled (not SNMP), the Extra Settings
parameters are available for configuration. Set the FEC and Modulation as
required.
10. Click the Add button below the Unmanaged Devices box to select the
target device(s) that will complete this channel. In the example used here,
this will be the demods for the two receiving sites.
The Select Object window will open containing the top level components for
the network, such as the satellite(s) and groups or sites.
11. Navigate through the Select Object window to select the corresponding
device(s) that will be used for this channel (figure 7-25) and click OK.
Take care to ensure that each device selected is the correct one. If groups are
displayed, double-click on the group that holds the target site. Double-click
on the target site to display the subnet list, then double-click on the subnet
that holds the target modem. Finally, double-click on the modem and select
the appropriate device.
The Unmanaged Devices box will now list the selected device(s).
If this is the only channel required for the circuit that is being created, proceed
to step 17.
If more channels remain to be defined for this circuit, continue with the next
step. For this example, a second channel will be defined for the P2P return path
from Remote 8 back to the Hub.
12. Click on the Add button in the lower section of the window.
The newly defined channel will be displayed in the channel table, showing
the associated parameters in the Managed Device, Ideal Rate, Power, and
Priority columns.
13. A second, incomplete channel appears directly below the first channel and
should be highlighted. If not, click on it to highlight it.
