About Your Internet and Voice
Wireless Gateway
The XFINITY™ Internet and Voice Wireless Gateway is the next-generation cable modem and Voice-Over-IP
(VoIP) adapter, integrated with home gateway features. It combines a two-line Embedded Media Terminal
Adapter with an integrated WiFi router and four wired Gigabit Ethernet RJ45 ports for multiple device
connection. Your Internet and Voice Wireless Gateway has been designed to meet DOCSIS®3.0
specifications.
Here’s what you get
...when you subscribe to both XFINITY Digital Voice and High-Speed Internet services:
•WiFi Technology — WiFi uses radio frequency to connect computers and other devices to a network
without wires. Your Internet and Voice Wireless Gateway can connect to b, g and n clients simultaneously.
•Fast Download Speed — Your Internet and Voice Wireless Gateway is DOCSIS 3.0 compliant with
speeds up to eight times faster than DOCSIS 2.0 cable modems.
•Easy Connectivity — Connect any WPS-compatible computer or device with just one button.
•Security — Because WiFi networks send information over radio waves, signals from your wireless
network can be intercepted by unauthorized users. Use the simple Home Network Wizard to securely set
up your WiFi broadband connection for WiFi enabled devices.
•Convenience — Simultaneously use four Ethernet ports for wired devices and 802.11b/g/n connectivity
for wireless devices. Choice between wireless LAN (WLAN) or wired Ethernet LAN connections.
•Flexibility — the ability to support two lines of telephone service, as well as high speed data; the ability to
use your existing router with your Internet and Voice Wireless Gateway
•Telephony Services — Complies with PacketCableTM 1.5
•Protection — Lithium Ion battery back-up (included with XFINITY Voice subscription)
Note: !If you haven’t already done so, please activate both XFINITY Voice and Internet
!services if you subscribe to both, or just XFINITY Internet services if you subscribe
!only to high-speed data services. Refer to the user guide you received with each of
!these services for activation instructions and information about XFINITY Voice and
!Internet features.
