Figure 1-3 shows the peak time for the Toronto office. There are more calls
arriving in Toronto than that office can efficiently handle. The Toronto
nodal supervisors enter network configuration control commands to
improve the efficiency within their queues. They also send a supervisor
message to Houston requesting that some of the calls be overflowed to
other nodes.
None of the nodes can see the amount of activity at the other sites.
However, the NAC can see the activity at all attached nodes. This allows
the supervisors to determine which queues are least active and most likely
able to handle an increase in calls. The Houston supervisors send messages
to Chicago and Los Angeles to inform them that there is an increase in calls
overflowed from Toronto. They then enter network configuration control
commands to overflow the excess calls from the Toronto office to the
Chicago and Los Angeles offices.
