Qwest Delivers First Nationwide All OC-192c Internet Protocol Network

DENVER, January 31, 2001 ? Qwest Communications International, Inc. (NYSE:Q), the broadband Internet communications company, today announced its entire North American Internet Protocol (IP) network now operates at OC-192c capacity ? or 10 Gigabits per second (Gbps) -- making it the first in the industry to offer customers IP transport and connectivity at this speed throughout the U.S.

While others have announced plans to deploy or are bringing up their first OC-192c IP segments, Qwest is carrying OC-192c IP customer traffic nationwide. At these speeds, the Qwest network could simultaneously transmit every major movie released last year to every major U.S. market in less than an hour.

More than a year ago, Qwest launched the first coast-to-coast, OC-192c IP link carrying commercial traffic. With its deployment of OC-192c IP equipment complete, Qwest is enabling customers nationwide to exploit the latest bandwidth-intensive applications and high-speed access to hosting services provided by its 14 U.S. CyberCenters(sm), each offering direct connections to the OC-192c IP network.

For this milestone, Qwest incorporated Juniper Networks Inc.'s (NASDAQ: JNPR) M160 Internet backbone routers into Qwest's existing broadband optical network, enabling speeds four times faster than existing networks and the lowest latency, greatest efficiency and lowest cost of operation and maintenance.

"As the demand for data transport reaches more than 600 terabits per week across our network, we continue to scale and stay ahead of the demands of our customers," said Mike Perusse, Qwest's senior vice president of engineering and technology. "With our innovative network architecture, the upgrade to all OC-192c was seamless and poises us for the next generation of network speeds ? OC-768c."

With its all OC-192c IP network fully operational, Qwest maintains its position as the industry leader in providing broadband applications and services, such as managed applications, streaming media and complex hosting.

"Qwest is extending its leadership in the communications arena by being the first to offer its customers the added benefits of end-to-end IP broadband connectivity at 10 Gigabit speeds," said Chris Nicoll, vice president of telecom infrastructure at Current Analysis. "By sticking to its strategy of constantly evolving and maintaining a multi-vendor network, Qwest is providing a solution that should be at the top of any customer's list for broadband services."

Having achieved this industry milestone, Qwest is testing terabit routers from Juniper Networks® and other companies, including Cisco Systems Inc. (Nasdaq:CSCO) and Avici Systems Inc. (Nasdaq: AVCI) for deployment in Qwest?s next generation IP network. These technologies would continue to enable Qwest to collapse multiple networks into a single IP core network, resulting in greater efficiencies and lower costs for customers.
