SMC Barricade SMC7904WBRB4

4-Port Wireless Annex B ADSL2/2+ Modem Router
Product Overview
SMC7904WBRB4, is a highly integrated residential Internet access
device which combines the function of Annex B ADSL modem, 802.11g
54Mbps wireless access point and 4-port 10/100 switch. It is fully
compliant with latest ADSL2/2+ standards and TR-067 compliant,
ensuring interoperability with your ISP’s network infrastructure. The
SMC7904WBRB4 provides high-performance Internet access, with
downstream up to 24Mbps and upstream up to 2Mbps, making it ideal
for residential users, home offices, and small businesses. With the
SMC7904WBRB4, computers on the LAN side can communicate and
share the Internet access and files via a wired or wireless network
connection. The NAT firewall with Stateful Packet Inspection (SPI),
Intrusion Detection System (IDS) & Denial-of-Service (DoS) provides
robust security from hackers. VPN pass-through is also provided for
securely connecting to your office or corporate network.
Key Features and Benefits
Enhanced ADSL2+ Technology
Instant, always on Internet connectivity for wired or wireless computers. The built-in ADSL2/2+ modem gives
unrivaled asymmetric high-speed data transfer rates with up to 24Mbps downstream, 2Mbps upstream.
Robust Security and Firewall Protection from Hackers
The NAT firewall with Stateful Packet Inspection (SPI), Intrusion Detection System & Denial-of-Service
provides robust security from hackers while VPN pass-through allows secure connectivity to your office or
corporate network. Access Control Lists with URL blocking allow you to control access to Internet services &
filter inappropriate web sites.
Quality of Service (QoS)
The SMC7904WBRB4 includes a build in QoS engine, which allow network administrators to allocate
network resources and to prioritize real-time applications like voice & video, to enable smooth Internet phone
(VoIP) and lag-free online gaming. WMM (WiFi Multimedia) delivers QoS to the wireless network, while IP
QoS prioritizes outbound internet traffic.
