SMC7204BRA

4-Port ADSL Router with Built-in Annex A
ADSL Modem

The ADSL BarricadeTM (SMC7204BRA) is an external Ethernet standards

based ADSL modem and Router that provides high-speed Internet access
to both the residential and the small and home office (SoHo) user. This new
Modem/Router provides unrivaled asymmetric high-speed data transport
over a single copper pair linking branch offices, home offices and individual
subscribers to their network service providers, including Internet service
providers.

With the ADSL BarricadeTM, investments are protected through the support
of popular DSL connection models such as PPP over Ethernet (PPPoE), PPP
over ATM (PPPoA), bridging and routing. The Barricade ADSL supports two
modes of operation. This modem can be configured to function as bridge to
support a single computer, then as the network grows, it can be reconfigured
as full featured Router to provide Internet access to multiple computers.

Another benefit of using the SMC7204 BRA in router mode is that you are also

protected by the built-in SPI/NAT firewall. Other features that are available in
Router mode include VPN pass-through, remote access communications, and
DHCP Server easy network setup.

This new high-performance ADSL Gateway has an easy-to-use web-based

management user interface that can be used to configure and manage your
network via a local or remote computer. For added control, this modem can
also be managed via the Command Line Interface (CLI), which can be initialized
through a Telnet session, or through a Windows-based configuration tool.
