Now you can implement Gigabit Ethernet switching in your network
for about the same cost as Fast Ethernet. ADTRAN's new NetVanta
1524ST Gigabit Ethernet switch delivers 24-port, managed, 1000
BaseT switching at a cost that is up to 50 percent less than
most managed Gigabit switches. The savings aren't a result of
cutting corners; they're a result of smart engineering! ADTRAN's
100% satisfaction guarantee on this product includes unlimited
technical support, free firmware upgrades, and a 5-year

IS TELEWORK TAKING OFF?

Recently an Atlanta based non-profit group worked with several
local businesses to start or expand telework programs. The
results should not surprise you. Telework increased productivity
and improved morale across the board. What else did this
telework initiative bring to the table? Click here for more:

Today's focus: FTTE is where the real cost savings are

By Jeff Caruso

Last time, I started discussing the cabling cost model developed
by the Fiber Optics LAN Section of the Telecommunications
Industry Association - but I didn't get to the most interesting
part.

While the model can give you cost estimates of an all-fiber
network and a hierarchical-star network, it also introduces the
concept of fiber-to-the-telecommunications-enclosure, or FTTE.
It turns out that this network cabling design brings the most
cost benefits of all.

In an FTTE network, you run fiber all the way from a central
location to an "enclosure" - a "$300 box with a fan," as FOLS
Vice Chair Dan Harman says. This enclosure can be placed close
to users, under the floor or in a ceiling space, and copper
cabling can run from the enclosure to desktops.

The network uses the best attributes of fiber and copper. You're
using fiber for the long runs (from the central location to the
enclosures on every floor), and fiber is better than copper for
long distances. "It's not just good at it, it's cheaper," Harman
says.

You're using copper to connect to desktops, and copper is better
than fiber when it comes to NIC costs.

Plus, you're not taking up valuable floor space with a wiring
closet on every floor. And moves, adds and changes are easier
than with a centralized cabling scenario.

FOLS says that its cost model shows FTTE setups coming in at 30%
to 40% less than the hierarchical star architecture.

The FTTE architecture was recently standardized by the TIA,
although the idea has been around in the form of Corning's "zone
cabling," for example, says FOLS Chair Gary Cawley.

The cost model is available for free (but requires registration)
from the FOLS Web site
