ADC Telecommunications Provides HDTV Transmitter and Fiber-Optic Transport For the First Commercially Available Digital Service Offering in Latin America.

MINNEAPOLIS & MEXICO CITY--(BUSINESS WIRE)--Aug. 17, 1999--

ADC Telecommunications, Inc. (Nasdaq: ADCT; www.adc.com) and Televisa, Mexico's largest television broadcaster, announced the availability of high definition television (HDTV) transmission in Latin America. Prior to the implementation of this system, HDTV transmission was used only in trials. Televisa's HDTV broadcasts, supported by equipment from ADC, are the first commercially available in Latin America.

The interoperability of ADC's broadcast products and cooperative effort among ADC's divisions and partners contributed to Televisa's successful implementation of this innovative service. "ADC's broad product line provided Televisa a total solution," said Fernando Bastarrachea, chief engineer for ADC. "We were able to provide the necessary transmitter, fiber transport and connectivity components, all from a single source."

The digital television (DTV) transmitter, digital audio and video patching, and fiber optics were supplied through ADC's Mexican subsidiary, ADC de Mexico, S.A. de C.V., and distributor, Dicimex, S.A. de C.V. In addition, ADC provided the digital uncompressed fiber optic transport between Televisa's transmission site in Cerro Tres Padres and its HDTV programming network in Mexico City.

"ADC's equipment and engineers have provided excellent technical capabilities and support for our HDTV transmissions and tests since 1997," said J. Leonardo Ramos M., high technology projects director and chief engineer of the HDTV project for Televisa.

The ADC equipment used in the total solution purchased by Televisa includes a DT800 series solid-state UHF transmitter. The transmitter utilizes the ADC-built DT1A 8-VSB modulator, which processes information such as video and/or audio in a digital format. A fully redundant, dual fiber-optic ring using ADC's DV6000 product line transports the signal through Televisa's network in Mexico City feeding its transmitter site. Also, ADC's fiber-optic and copper patching products for both analog and digital video/audio signals are installed throughout Televisa's network.
