Automated system that needs to periodically use the line while giving the voice user the highest
priority
A common use for these features would be an automated system that needs to
periodically use the line while giving the voice user the highest priority.
The automated system would make a connection when the line is free. It would do this
without disturbing the line if the line is in use. The automated system would periodically
retry the connection until the line is free. Once the line is free it would dial and make its
connection. If a voice user wishes to use the line while the modem is connected. The
modem will drop the line and give the line to the user. The modem will then try to regain
control of the line by once again periodically retrying to establish a connection.
