LEVEL ONE RAMPS TOWARD HDSL PRODUCTION

 FOLSOM, Calif., Oct. 26 /PRNewswire/ -- Level One Communications Inc. (NASDAQ: LEVL) today announced the first production orders for its High Speed Digital Subscriber Line (HDSL) Data Pump. The Level One HDSL program is supported by a consortium of leading international telecommunication equipment suppliers working toward a common implementation of HDSL for T1 and E1 systems.
 HDSL is an enhancement to the T1/E1 transport mechanism. Both T1 and HDSL use two wire pairs to provide a bandwidth of 1.544 Mbit/s. Since HDSL does not require line conditioning or repeaters, operating telephone companies can reduce their costs while offering customers faster hookup to services they now offer with T1/E1 transport systems.
 In a T1 network, each pair carries a 1.544 Mbit/s data stream in a single direction. HDSL breaks the 1.544 Mbit/s T1 signal into two 784 Kbit/s components, each of which is carried bidirectionally over a single wire pair. Sophisticated echo canceling techniques reduce Near End Cross Talk (NEXT) to enable successful bidirectional transmission over a single wire pair.
 "These orders are a validation of our design approach," said J. Francois Crepin, vice president of Business Development at Level One. "We have reached a significant milestone in the development of a cost- effective HDSL solution."
 Level One and the consortium expect that their efforts will lead to worldwide availability of the HDSL transport method initially recommended by Bellcore, and currently being specified by North American ANSI (American National Standards Institute) and ETSI (European Telecommunications Standards Institute) committees.
 Level One designs, develops and markets mixed-signal application specific standard integrated circuit products ("ASSPs") for high-speed digital signal transmission and networking connectivity applications. Level One combines its strengths in analog and digital circuit design with its communications systems expertise to produce mixed-signal solutions with increased functionality and greater reliability, resulting in lower total system cost.
