tw telecom has teamed with Columbus Networks to offer the carrier an advanced
resilient hub into a national footprint from their landing station in Miami.

"Our initial experience with tw telecom has enabled us to successfully connect
to many U.S. customer locations from one network access point," said Peter
Collins EVP and CTO of Columbus Networks. "The uniqueness of E-Access
provides us with additional seamless and scalable connectivity to extend our
regional managed business solutions to customers with offices here in the
USA."

According to Nan Chen, President of the Metro Ethernet Forum (MEF), MEF
standards are designed to encourage development of ubiquitous Ethernet
connectivity across the world. "tw telecom's E-Access is an industry first
in helping carriers reach thousands of enterprise buildings from one network
access point instead of needing to have local network to network connections
in each city or market."

Through a single network connection in one location, tw telecom's Business
Ethernet service is delivered to virtually any building or data center in the
United States across
tw telecom's 75 market national foot print. The E-Access solution, based on
MEF-compliant Ethernet Access standards, provides ready-made infrastructure
for carriers to quickly and easily reach their end user locations across a
secure, scalable and trusted network.

"E-Access with an external network to network interface (ENNI) provides
carrier, application, and data center service providers with a single point of
access into tw telecom's  vast national Ethernet footprint," said Tom Marx,
President of tw telecom's Wholesale Services. "These providers are
recognizing the need for a secure and scalable network as they roll out
business critical applications to their customers. Many of these carriers
typically do not have their own network to connect everywhere they need to
go. They look to tw telecom to deliver secure, scalable and predictable
network connections and solutions that help them deliver applications to their
customers."

"With tw telecom's E-Access, customers can avoid capital investments, reduce
operating costs and more easily manage their network capability," Marx said.
