MIDAS 4.X NMS Configuration, Rev.6
2–6 Setup and Operation
Satellite Name Enter Satellite name.
System Parameters:
Allocation Factor 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.
Step Size This is the smallest unit of bandwidth that will be displayed and allocated on the Space Segment.
Range: 2.5 to 25.0 kHz, in 2.5 kHz increments.
Keep Logs for This parameter sets the number of days that logs will be kept before they are deleted from the
system.
Lock Time 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 NMS if the circuit failed due to
carrier loss.
