This is a factor, or multiplier, used as a carrier spacing placed between carrier
assignments to avoid interference (roll-offs, skirts). A typical Allocation Factor
is 1.4. Using a larger number will provide a larger spacing, but will also take
up valuable transponder space.

This is the smallest unit of bandwidth that will be displayed and allocated on
the Space Segment. Range: 2.5 to 25.0 kHz.
Note: This will define the frequency resolution of the MIDAS System.

This is the IF Center frequency of the transponder, depending on the specific
hardware involved, 70 or 140 MHz.
Caution! The Step Size and IF Center values should be changed only
when configuring the system for the first time, or if a substantial system
reconfiguration is required. Changing these values requires a system reset
(reboot), and will cause the loss of key bandwidth related information.
Additionally, all Active Calls will be deleted.
After the system is restarted, the Space Segment and Control Channels
must be reconfigured.

This sets the amount of time, in seconds, that a node will wait after a circuit is
successfully established before checking the traffic modems for loss of carrier.
It is only after this "stabilization" period that the node sends a terminate
message back to the Controller Server if the circuit failed due to carrier loss.

When this checkbox is selected, the MIDAS controller can perform power
calculations during call setup, as defined on the Power Setup window.
