Voice-enabled Residential/Small-office Gateway/Router with Embedded DSL Modem (xDSL IAD)
A voice-enabled residential/small-office gateway/router with embedded DSL modem, also known as an xDSL IAD, is part of a voice-over-DSL solution. It enables the bundling of multiple derived voice lines, high-speed data and continuous Internet access over a single DSL connection. It typically combines a DSL modem with a router, firewall and varying plain old telephone service (POTS) port configurations. It can be a wired device or include a wireless access point.
