Lucent Digital Radio and Moseley Associates Announce Agreement to Test Digital Audio Broadcast System.

WARREN, N.J.--(BUSINESS WIRE)--Aug. 23, 1999--

Lucent Digital Radio, a wholly-owned subsidiary of Lucent Technologies (NYSE: LU), and Moseley Associates, a leader in the design and manufacture of radio broadcast equipment, today announced that they have agreed to jointly test Studio Transmitter Link (STL) technology that will further develop Lucent Digital Radio's In-Band On-Channel (IBOC) Digital Audio Broadcasting (DAB) system. Tests will commence immediately and will be conducted at both Lucent Digital Radio and Moseley facilities.

The STL link, an integral part of the radio broadcast chain, connects a radio station's studio to its transmitter site. The Lucent Digital Radio IBOC system is designed as an end-to-end solution that will enable broadcast stations to seamlessly convert to an all-digital AM or FM broadcast scheme.

Lucent Digital Radio recently conducted tests of its IBOC FM system on National Public Radio (NPR) member station WBJB-FM. These tests were the first time that an IBOC system successfully passed a hybrid (both analog and digital) signal over a radio station's antenna and transmitter without affecting the host analog signal.

"Working with Moseley, an acknowledged leader in the STL field, will further demonstrate to the radio industry that our IBOC system delivers sound results," said Suren Pai, president of Lucent Digital Radio. "Our end-to-end IBOC system is designed to ensure that radio broadcasters make a seamless transition from analog to an all-digital IBOC future."

"We believe that IBOC is a tremendous opportunity for all involved in the radio broadcast industry, and we look forward to helping Lucent Digital Radio develop the best possible IBOC system," said David Chancey, national sales manager of Moseley Associates. "Furthermore, our joint efforts will allow our Starlink STL customers to understand how our product works with 21st century radio technology."

Lucent Digital Radio's IBOC DAB system is an enhancement to current analog AM and FM radio broadcasting systems. It will provide greatly enhanced sound quality for AM radio, CD-like quality for FM radio, as well as interference-free reception and innovative new data services.

Lucent Digital Radio draws on several patented Bell Labs digital audio and channel coding techniques that provide robust digital signal delivery in an impaired broadcast channel, including Lucent's Perceptual Audio Coder(TM) (PAC(TM)) technology, which delivers CD-like quality audio at 96 Kilobits per second; Unequal Error Protection, which prioritizes information based on its impact to audio quality; and Multi-Streaming, which provides for a more robust signal in an impaired channel.

The IBOC approach will allow broadcasters to introduce digital audio programming to listeners on their current dial positions using existing transmitters and antennas. IBOC DAB is both backward- and forward-compatible: current AM/FM receivers will still be able to receive the existing analog signals in the new system. When a station elects to turn off the analog signal in the future, IBOC DAB-compatible receivers will operate with the remaining all-digital signal.

A Lucent Technologies venture, Lucent Digital Radio is developing IBOC DAB technology for AM and FM broadcasting worldwide. Lucent Digital Radio's IBOC system will be resistant to multipath and other forms of interference that impair current analog transmissions.
