Footprint with Mid-Band Ethernet Solutions from Hatteras Networks
RESEARCH TRIANGLE PARK, N.C.--(Business Wire)--Hatteras Networks, the Mid-Band Ethernet(TM) market, technology
and services leader, today announced that Cavalier Telephone and TV
has selected Hatteras Networks Mid-Band Ethernet solutions to underpin
its Ethernet Express business service. Cavalier, one of the nation's
largest competitive local exchange carriers (CLECs), already serves
650,000 business customers in 15 states and the District of Columbia
from its fiber network. This new addition to the Ethernet Express
service represents a tremendous opportunity for Cavalier to extend its
footprint throughout the Mid-Atlantic and Eastern United States.

"Ethernet Express enables us to cost-effectively deliver native
Ethernet services at far greater speeds than traditional T1s," said
Brad Evans, Chairman of Cavalier. "With Hatteras Networks Mid-Band
Ethernet solutions installed, our business customers have the
flexibility to purchase Ethernet bandwidth in increments that are
suitable for their business requirements today, with the ability to
scale as their businesses grow."

rigid T1 service increment structure, gaining greater flexibility in
the types of services they can offer its business customers. Cavalier
is leveraging Hatteras Networks' Mid-Band Ethernet solutions to build
a portfolio of converged services over one Ethernet connection
including Internet, VoIP & Private LAN. The service is available in
hundreds of carrier exchanges across seven states and Washington, D.C.
at speeds from 3 to 45 Mbps.

"Cavalier has created a network to serve a rapidly evolving set of
business requirements for higher performance, greater flexibility and
unmatched resiliency," explained Kevin Sheehan, President and CEO of
Hatteras Networks. "Cavalier has built a clear competitive advantage
by leveraging a cost-effective way to extend their Ethernet Express
services to businesses served by copper facilities."
