How the Class Request Works
When a class request is made, the process is as follows:
D
Search through local hub group (see figure below) for primary class,
then secondary class. If no available ports on local hub group, unit
will place the call in queue for any available primary port or secondary
class port.
D
A call is made to remote unit(s), a
CALL IN PROGRESS
message displays.
The unit searches the primary, then secondary class. If no available
ports, unit will place the call in queue.
D
When a connection is made, all other pending queue requests are
cleared.
There is no way to determine which remote unit will be connected if class
exists on more than one remote node.
