GTE and ADC Team to deliver VideoConnect Broadcast Video Service

GTE Becomes First Major Telecommunications Company to Use ADC's AccessPoint System to Offer Broadcast Video Over Standard, Open Networks

MINNEAPOLIS and IRVING, Texas -April 3, 2000 - ADC (Nadaq: ADCT; http://www.adc.com and GTE today announced that GTE will use ADC's AccessPoint Universal Media Access System to deliver its VideoConnect broadcast video service to customers in California and Florida. GTE's VideoConnect service delivers high-speed, broadcast quality video transmission and distance learning capabilities at speeds up to 270 megabits per second (Mbps). Using ADC's AccessPoint system for MPEG-2 video compression, GTE can transport video over standard fiber or ATM networks to its customers at variable speeds that were until now only available in TV1 analog and 45 Mbps, thereby reducing costs.

GTE's VideoConnect service is delivered through two state-of-the-art transmission centers in Los Angeles and Tampa, Fla., and on a point-to-point basis. These facilities provide customer-controlled switching of video transmissions, which offers a cost-effective, secure and convenient way for video to be delivered to and from broadcasters, producers and editors at broadcast television stations and video production companies. Through customer-controlled software, customers can manage their own video switching from their desktop, thereby eliminating third-party scheduling conflicts. AccessPoint features multiplexing capabilities allowing GTE to maximize the use of existing copper or fiber, which reduces expenses while improving broadband video quality for customers.

"ADC's system allows us to successfully access and deliver video signals over standard networks," said Joe Palmer, group marketing manager for GTE Network Services, the local phone unit of GTE Corp.. "The system's high-level of quality and consistency have made it a fundamental piece of our VideoConnect service."

WFTS TV in Tampa, an ABC affiliate, was one of the first broadcast TV stations to utilize GTE's VideoConnect service and ADC's AccessPoint system. "We've found that GTE's VideoConnect services have been very reliable," said Jack Winter, broadcast operations and engineering manager for WFTS TV/DT. "By being responsive and working closely with us, GTE helps us keep monthly costs down as well as reducing our capital expenditures. We are now using VideoConnect for high definition broadcasts."

"We're excited that GTE is the first major carrier to implement AccessPoint for broadcast video services," said Karl Rookstool, vice president of marketing for ADC's Wireline Systems Division. "Whether the application is point-to-point or public ATM networks, AccessPoint delivers quality broadcast video. With a standard network transmission method, carriers like GTE can offer cost-effective video delivery services to their customers."

GTE's customer-controlled switching facilities can be utilized from customer's homes or offices. The video transmission centers support both analog, National Television Standards Committee (NTSC) video and audio, and compressed/uncompressed component serial digital video and digital audio. The service is available in three different speeds, including analog TV1 format and digital and analog video speeds from T1 to 270 Mbps. Each format adheres to all applicable broadcasting standards.

ADC's AccessPoint system allows for the instantaneous connection of video, audio and data over broadband ATM networks. The system's MPEG over ATM architecture requires less bandwidth to transmit very high quality video images, enabling carriers and network operators the ability to offer more bandwidth efficient, cost-effective video service in point-to-point and point-to-multipoint environments. AccessPoint integrates video, voice and data interfaces, MPEG compression, and ATM transmission interfaces into a single, modular system.
