FEATURES
• Breaks distance and speed barriers —
extends a network as far as 6000 feet
or achieves 50-Mbps full-duplex speeds
over voice-grade wiring.
• Less expensive than using CAT5e or
fiber to connect remote Ethernet LANs,
PCs, or 10BASE-T/100BASE-T devices.
• Great for bandwidth-intensive
applications.
• Easy to configure; DIP-switch controls
set line rates.
• Six symmetric or asymmetric settings.
• Includes a pair of extenders that
work together to create a transparent
extension between two peered LANs.
• Auto MDI-X ports adapt to the type
of Ethernet cabling —no crossover
cabling required!
• Once configured, operates transparently
without any further user intervention.
• Link-side surge suppression.
• Front-panel LEDs indicate activity.
Deliver greater bandwidth to applications over an existing phone line.
OVERVIEW
Go farther and faster without spending a lot on cabling.
With the BLACK BOX®High-Speed Ethernet Extender Kit,
use ordinary voice-grade wiring to connect links far beyond
the 328-foot (100-m) distance limit of Ethernet.
Depending on the distance between connections, you can
achieve even greater speeds, too—as fast as 50 Mbps upstream
and downstream over 24-gauge, 0.5-mm cable.
And, in many cases, you can achieve this distance without
having to supply additional wiring. By using existing two-wire
unconditioned twisted-pair cabling, you can use your legacy
wiring infrastructure and eliminate the expense and hassle of
having to run new UTP or fiber optic cable.
The kit includes a pair of extender units. Each unit can be
configured as either a local or remote unit simply by flipping
a switch. They have an RJ-45 port for the interconnection and
a shielded RJ-45 port for a LAN link. Because the LAN port has
an automatic MDI-X feature, you can connect it to a hub or PC
with a straight-through or crossover cable.
Easy to deploy for many demanding applications.
The High-Speed Ethernet Extenders are designed to easily
interconnect a central LAN to remote devices or remote networks
located at lot farther away.
Use them, for instance, to deliver Ethernet links to peered
10BASE-T/100BASE-TX Ethernet LANs or remote PCs in buildings
located beyond the typical 328-foot Ethernet distance limit.
Because they use ordinary voice-grade copper, the extenders
give you an easy-to-deploy solution. Connect one to a network-
enabled device—whether it’s a security camera, a server, or
workgroup PC—and simply plug it into a nearby RJ-11 jack to
provide the interconnection to your central network. The
RJ-45 connector on the extenders’ twisted-pair interconnec-
tion interface is polarity insensitive and is wired for a two-
wire interface.
What’s more, their larger throughput provides you with
bandwidth greater than that of traditional copper-wired
technologies—with performance approximating that of fiber
optic technologies. For this reason, they’re particularly useful
in medical imaging, LAN broadcasting, videoconferencing,
and Voice over IP (VoIP) applications.
You choose the rate to fit user or customer needs.
By having six selectable line rates, you can tailor the reach
and rate of the extenders to a specific application, while also
taking into consideration the noise-level constraints of the
specific environment. Use asymmetrical rates for streaming
audio and video-on-demand applications. Or choose
symmetrical rates to deliver business-class VoIP or high-
resolution imaging.
The extenders also bring greater flexibility to service
providers, especially those wanting to differentiate their
services and provide various speeds to customers. They’re
particularly useful at satisfying customer demand for triple-
play services by enabling you to deliver HDTV, VoIP, and Web
access without having to use more expensive cable media.
NOTE: Actual distance and link performance may vary
depending on the environment and gauge type of wire
you use.

The High-Speed Ethernet Extender Kit passes higher-layer
protocols across the physical link, and it supports 802.1Q VLAN
tagged and untagged traffic, ensuring that VLAN information
reaches the remote side and is propagated across your network.
All data is forwarded across the link unmodified, with the
extenders adding and deleting MAC addresses automatically
and passing only packets meant for the remote peered LAN
over the interconnection.
The extenders work in pairs, with one of the units configured
as a local unit and the other configured as a remote unit.
It doesn’t matter which end is the local side and which is the
remote side; the link is always initiated by the the unit set to
operate as the remote unit. As long as the local unit is powered
on, the remote unit can establish a link by being powered on
or by having its power reset.
Eight DIP switches enable you to quickly configure each
extender unit for a wide variety of applications. Set their line
rate for either symmetric or asymmetric operation and configure
their Ethernet network speed (10 or 100 Mbps) for either half-
or full duplex. You can also set them to autonegotiate for
duplex and network speed, as well as disable the Ethernet
interface when no interconnection link is detected.
Once configured, the High-Speed Ethernet Extenders
operate transparently. To monitor or troubleshoot operation,
observe the three front-panel LEDs.
• A solid green PWR LED indicates that it’s powered on.
• A sold green LINK LED indicates that an end-to-end link
between units has been established.
• A solid green ETH LED indicates that a 10/100 Ethernet link
has been established. When the extender detects network
activity, this indicator flashes.
