An ATM network which collects billing data from ATM switches in a switched voice network. A full, partial or summary report is produced. The ATM switches can be anywhere in the network. The ATM network includes the ATM switches a data collection, unit and billing systems. The data collection unit collects pertinent data and outputs the data to an AT&T billing system or any other desired billing system. Because ATM systems use cells for carrying information, the system is faster and more efficient than TDM systems. In addition, the output of the data collection system is table driven and can be defined to match the input needs of TDM billing systems without increased effort or expense.

Why it's free to use
- Filed February 28, 1997 and granted January 1, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 28, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 28, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
