Model DG800 for Annex A (ADSL over analog lines)

The ADSL DG800 integrates a full-rate ADSL modem, router, firewall, four-port 10/100
Ethernet switch, and VoIP phone port into a single cost-effective product.

The TelePort feature provides a phone port that lets you use your standard single-line phone for conventional phone calls or free and very low-cost Voice Over IP (VoIP) calls.* Because the DG800 integrates Internet telephony with a full featured
ADSL gateway, setup is easy and system security is ensured. Integration of the voice processing with the firewall in the router ensures reliability of VoIP calls and reduces service provider support requirements.

The DG800's built-in four-port Ethernet switch eliminates the need for a separate Ethernet hub for most home networks and many small offices.

Intelligent relay that allows a single phone to place and receive both VoIP calls and calls over the Public Switched Telephone Network (PSTN). PSTN Fail-Over allows the DG800 to automatically route calls over the dial-up phone network when power is
lost. PSTN support also allows emergency dialing using services like 911 or 112 calling.

The DG800 uses Session Initiation Protocol (SIP) for compatibility with a wide range of VoIP infrastructure equipment. Quality of Service prioritizes voice data packets over other packets, so that voice quality remains high, even when there is substantial non-voice traffic.

Setup is easy using any authorized local or remote computer's Web browser and the graphical user interface built into the DG800. After setup, the DG800 voice featureswork even without an attached computer. Flash memory allows easy firmware

updates, including additions to the voice compression codecs.
