CLEC
It's an exciting time to be a competitive local exchange carrier (CLEC). With more carriers entering the
market, customers know they have many options for service. In fact, shopping around for the most
economical and best quality solution is becoming almost as basic for businesses as casual Fridays. For
new competitors, the key to getting customers' attention is finding a cost-effective way to deliver and
differentiate their services. The opportunity is clear when CLECs take a look at the exploding T1 ser-
vice delivery market. T1 services are growing at 30 to 40 percent annually to meet the demand for hicap
voice, ISDN-PRI, Frame Relay, Internet access, PCS access, and ATM services.
CLECs that find a way to bundle these services and offer both voice and data over the same line will
set themselves apart from the competition. Customers benefit from one-stop-shopping, while the
CLECs reduce the cost of doing business by bundling services over the same T1 line. With a grow-
ing number of businesses now having at least one T1 line, the potential to generate more revenue for
your business is clear. Currently, more than 60 percent of businesses with 50 or more employees
have at least one T1 line, and that number is growing fast. For CLECs, T1-based services can account
for a majority of total revenue and a corresponding percentage of profit. Capitalizing on this potential,
however, takes careful planning. One of the key decisions facing CLECs is selecting complementary
transmission and access products for optimal service delivery and improved customer satisfaction.
Making the right choices will position CLECs to take advantage of the exploding local services market.
To capitalize on the opportunity, CLECs must rapidly capture revenue-
generating customers. To maintain a competitive advantage,
CLECs must minimize their total service access and
delivery cost. Likewise, they must find a reliable
way to reduce their total costs associated with
trouble resolution, service restoration, and
maintenance. Carriers that want to stay
ahead of their competition must make the
right business decisions to remain profitable.
CLECs currently building their customer bases need a service delivery architecture that can help them
control overhead expenses. At the heart of the preferred solution is unbundled copper—the method that
can save CLECs a bundle over traditional approaches of T1 delivery.
Unbundled copper is the best replacement for leasing T1 lines directly from the incumbent provider.
CLECs that lease T1s, commonly referred to as Type II lines, tie into these circuits at the ILEC facility
where the T1s are typically backhauled to their local digital switch. The remote end of these circuits ter-
minates into a standard channel bank housed on the customer premises.
Leasing T1 circuits directly from the incumbent local exchange carrier (ILEC) is most economically feasi-
ble in situations where the size of the CLEC customer base can’t justify the cost of collocation. But leas-
ing T1 circuits from an ILEC is expensive, and once a CLEC’s customer base grows, it’s a wise decision
to migrate to a more economical method of service delivery. Once CLECs have enough customers ser-
viced from the same ILEC central office, they can negotiate collocate space, order unbundled loops, install
equipment into that space, and systematically convert customers over to unbundled copper. When
migrating, CLECs should look for a service delivery system employing high bit-rate digital subscriber line
(HDSL) over unbundledcopper elements. HDSL is a transmission technology that provides cost-effec-
tive delivery of high-speed services. HDSL offers long reach enabling signals to be transported on copper
cable over distances up to12,000 feet without repeaters.
Additionally, as ILEC collocation space is at a premium, a solution that minimizes the number of compo-
nents, such as integral M1-3 multiplexers, is important in conserving space and improving reliability. It
also offers a fiber-quality signal with installation times measured in hours not weeks. There is now a new
generation of HDSL-enabled devices encompassing these important features, minimizing installation
costs, making it easier for carriers to take advantage of this technology.

HDSL
• HDSL is a mature technology used to provi-
sion 80 percent of all new global T1 circuits
• Gives CLECs major savings over leased T1s,
providing them with a more profitable business
• Allows carriers to differentiate themselves by
offering bundled services
• Reduces maintenance cost
• Allows CLECs to retain complete end-to-end
control over their service delivery network
• Several hundred thousand lines in the United
States and growing
• Increased reliability (crosstalk tolerant), robust

Control the Wire, Control Your
Business
In order for a CLEC to get the maximum bene-
fit from migrating to less costly HDSL-based T1
service delivery, they must control the wire.
Although the ILEC will still always own the
wire, CLECs can control services. Controlling
the copper pairs improves trouble response
and customer satisfaction, thereby increasing
revenues.
To gain control of those pairs, CLECs must
establish a collocate space at the ILEC end
office and select the right transmission plat-
form and access solution. When selecting a
solution, CLECs should choose a complete
system with intelligent technology that
allows them to provide superior service for
less money. The transmission platform
and access solution should be based on
ILEC friendly technology, reduce turn-up
cost, and facilitate cost-effective network
administration. In addition, a complete sys-
tem should conserve collocate space, be
simple to install, and allow for advanced
performance monitoring. The complete
system approach has many advantages,
including:
• Minimizing total service access and
delivery costs by using unbundled loop
versus Type II leased T1s
• Rapidly capturing revenue-generating
customers by offering bundled voice and
data services
• Reducing cost of trouble resolution,
restoration, and maintenance end-to-end
• Increasing profitability of existing cus-
tomers
• Enhancing competitive advantage
• Improving quality of service
