ATA: Analog Terminal Adapter
Analog Terminal Adapter (ATA) is a device that allows a normal PSTN telephone to connect to the Internet in order to make or place telephone calls. An ATA device may work in conjunction with a computer, such as a USB ATA device, or it may be a stand-alone device that communicates with a service provider over the Internet. The latter types of devices are common with many broadband VoIP service providers.
