ATM data rate

The ATM (asynchronous transfer mode) data rate is the rate measured at DSLAM (Digital Subscriber Line Access Multiplexer) level, unlike the IP data rate, which is measured between the DSLAM and the subscriber.

Internet access providers now only communicate by ATM data rates, a marketing ploy allowing a relaunching of the speed race.

Example: 20 Mbps ATM = 16 Mbps IP.
