Switches are innovative “in the wall” devices
providing a unique, cost-saving way to expand LAN connectivity
in almost any network environment. The switches replace a
one-port LAN wall outlet, giving four switched Fast Ethernet
ports for connections. They are ideal for expanding LAN port
capacity in small-office or enterprise businesses, government offices,
classrooms, public kiosks, and shared office spaces – particularly
suitable for older or hard-to-wire structures. IntelliJack Switches are available in designs for both US-style and
European/UK style data outlets for easy deployment in any
networking environment. The upgrade from single port Ethernet
outlet to four auto-sensing 10/100 switched ports is fast and easy,
requiring no new cabling. The IntelliJack Switches NJ225 and
NJ220 are managed four port switches with advanced capabilities such
as VLANs and traffic prioritization. The IntelliJack Switch NJ105 and
Network Jacks NJ100 and NJ90 are unmanaged switches for greater
economy.

Understanding Wireless LAN Standards
Wireless Bluetooth technology delivers untethered connections
among PCs, handhelds, mobile phones, printers, and a host of
other Bluetooth-enabled devices.
3Com Wireless Bluetooth PC Card with XJACK Antenna
• For connections between notebook PCs and other Bluetooth
devices, as well as “light” network access
• Securely share files with other Bluetooth PCs, synchronize
handhelds, connect to the LAN through a Bluetooth access
point, or dial up the network with a Bluetooth cell phone
3Com Wireless Bluetooth USB Adapter
• Share files with other Bluetooth PCs with point-and-click ease
• Synchronize PCs and handhelds with the push of a button or
jump on the Internet or network through a Bluetooth access
point, or using a Bluetooth phone
Proliferation of wireless standards can be confusing. This quick
guide will help you choose between a, b, and g standards.
• 802.11g and 802.11a products provide speeds up to 54 Mbps,
almost five times faster than 802.11b products and perfect for
high-bandwidth applications; products that support Super A/G
Turbo provide speeds up to 108 Mbps
• 802.11g products offer high-speed wireless connections
and are also backward compatible with 802.11b products,
preserving existing 802.11b investments
• 802.11b products are the most widely sold and have
a large installed base. They provide speeds up to 11 Mbps
• 802.11a products offer high speed and operate at the less
crowded 5 GHz frequency, but they are not compatible with
legacy 802.11b networks or 802.11g networks

3Com Security Solutions
3Com Embedded Firewalls
The 3Com Embedded Firewall solution extends centrally managed,
hardware-enforced security to notebooks, desktops, and servers
across the organization inside and outside the network perimeter.
This innovative combination of policy server software and firewall
card hardware safeguards network assets with superior tamper-
resistance that software-only firewalls can’t match.
• Embeds firewall functionality into PC Card hardware, making
security virtually tamper-proof; unlike software-based products,
firewall operates transparently to host OS and end users
• Lets security administrators distribute and build the configuration
they want—when and where it’s needed
• Streamlines and automates security administration; enables
quick response to network attacks; prevents security from being
modified or disabled at the host
