Qwest Activates Major OC-192 Four-Fiber Network Ring and Indianapolis to Chicago Segment

DENVER, October 15, 1998 ? Qwest today announced the activation of its second Dense-Wavelength Division Multiplexed (D-WDM) OC-192 four-fiber bi-directional line switched ring (BLSR) on its 18,449-mile nationwide Macro CapacitySM Fiber Network. The 3,186-mile SONET ring connects Denver, Kansas City, Houston and El Paso. Using this configuration, network capacity on the four-fiber ring is dramatically increased, and 100 percent service survivability is ensured through the instantaneous rerouting of traffic in the event of a fiber cut or other disruption. In addition, Qwest has lit an additional 215-route mile segment between Indianapolis and Chicago.

A recent report found that while it takes almost a year to double network capacity, Internet traffic continues to double almost every four months. In order to meet the growing traffic demands of customers, Qwest is aggressively deploying its nationwide fiber optic network and currently has initiated construction on more than 95 percent of the network. Imbedded in the Qwest Macro CapacitySM Fiber Network is the world?s first commercially available OC-48 (2.4 gbps) IP network. The OC-48 network service will provide Qwest?s customers with virtually unlimited bandwidth for sophisticated multimedia, e-commerce and data applications.

"Technologies like the D-WDM four-fiber solution allow us to not only increase network capacity, but also to provide our customers with unprecedented service level agreements that ensure 100 percent network availability," said Larry A. Seese, executive vice president of network engineering and operations for Qwest. "In addition, we?re excited to bring Chicago online and to continue to meet our aggressive build schedule to satisfy the growing demand of communications services for residential and business customers."

In June of 1998, Qwest activated the world?s first D-WDM OC-192 four-fiber BLSR between San Jose, San Francisco and Oakland.

The Qwest Macro Capacity Fiber Network

Qwest?s planned domestic 18,449-mile network will serve over 130 cities, which represent approximately 80 percent of the data and voice traffic originating in the United States, upon its scheduled completion in the second quarter of 1999. To date, approximately 9,100 miles of the Qwest Macro Capacity Fiber Network are activated, and construction has commenced on 17,773 miles. Qwest?s transcontinental segment extends from Los Angeles to Sacramento and across to New York. Additionally, Qwest owns transatlantic submarine capacity linking the United States to Europe and will jointly own a transpacific submarine cable system connecting the U.S. to the Pacific Rim. Qwest is also extending its network 1,400 miles into Mexico with completion slated for late 1998.

The Qwest Macro Capacity Fiber Network is designed with highly reliable and secure bi-directional, line switching OC-192 SONET ring architecture. Upon completion, the network will offer a self-healing system that provides the ultimate security and reliability by allowing instantaneous rerouting in the event of a fiber cut.
