Abstract
As broadband services roll out to an ever-larger share of households, PSTN replacement services based on VoIP and broadband access are becoming more pervasive. Service providers - both incumbents and new competitors - are using Analog Terminal Adaptors (ATAs) to rapidly deliver voice service to "the broadband masses". The ATA enables service providers to deliver a PSTN-like service directly over a customers' broadband access connection. This white paper explains the ATA and describes some of the essential building blocks and features that enable an ATA to replicate PSTN service quality levels.
