preempted.
Normal priority circuits,
Which cannot preempt other circuits. Other high-priority
circuits can preempt these circuits.
The traffic channels can have the following priorities associated with them:
High priority,
Which means that all the circuits originating from this traffic
channel would be “high priority circuits” as defined above.
Normal priority,
Which means that all the circuits originating from this traffic
channel would be “normal priority circuits” as defined above.

MIDAS can support up to 300 traffic nodes. Each node can support up to 30
traffic channels. Refer to Chapter 1 for descriptions and illustrations of a
Single-Channel traffic node and Multi-Channel traffic nodes.
