Chapter 2 – AT Commands

Automated system that needs to periodically use the line while giving the voice user the highest priority

A common use for these features: An automated system that needs to periodically use the line while giving the voice user the highest priority. The automated system makes a connection when the line is free. It does this without disturbing the line if the line is in use. The automated system periodically retries the connection until the line is free.

Once free, it dials and makes its connection. If a voice user wishes to use the line while the modem is connected. the modem drops the line and gives it to the user. The modem will then try to regain control of the line by once again periodically retrying to establish a connection.
