Actiontec GT701D ADSL Modem

Overview
The Actiontec GT701D is an ADSL2+ router/bridge (1 LAN port) that was commonly used by subscribers to Qwest Telephone's DSL service (USA). It is an early example of an Internet appliance that met the US EPA's requirements for an ENERGY STAR  designation.

The modem uses the Texas Instruments TNETD7100 system-on-a-chip (SoC) from the AR7 family. This SoC provides bridging or routing, a digital signal processor, the DSL physical layer including a line driver, and the Ethernet physical layer. The AR7 family are Texas Instruments' designs  that first entered service in 2003. The family of designs was sold to Infineon in 2007, and the wireline business of Infineon was in turn spun-off in 2009 to form Lantiq. Lantiq is now part of Intel.

The firmware provided with the modem supports both a web-based interface and telnet log-ins; Telogy's ADAM2 bootloader (later TI's PSPboot ) allows for firmware updates using FTP.
