C.P. Clare to Demonstrate Home Phoneline Networking Solution At HomeNet '99.

BEVERLY, Mass.--(BUSINESS WIRE)--July 26, 1999--

-- Low Cost, Next Generation Technology "Turbos" to 10+Mbps

Speeds with No New Wires --

C.P. Clare Corporation (NASDAQ:CPCL) today announced plans to demonstrate real-world, multiple-PC home networking using its low-cost 10+Mbps phoneline network physical layer (PHY) transceiver at HomeNet '99, July 27-29, 1999 in San Francisco. The Company's high speed PHY transceiver, branded JackRabbit(tm), economically networks multiple PCs and peripheral equipment over existing phone lines in a residence or small office without interrupting normal voice telephone service or requiring any new wiring. Along with typical small office/home office (SOHO) PC network applications, such as file and printer sharing, JackRabbit technology allows the rapidly growing number of multiple-PC home consumers to easily create a broadband network within their homes for shared high speed Internet, multimedia, network gaming and home security applications.

Optimized for the complex and dynamic home phoneline network communication medium, C.P. Clare's PHY transceiver is extremely robust and overcomes the most difficult line impairments to ensure high data throughput along with a high level of consumer satisfaction. Unlike complex Quaternary Amplitude Modulation (QAM)-based PHY transceiver solutions, C.P. Clare's JackRabbit PHY is implemented in silicon without the use of a Digital Signal Processor (DSP), resulting in a much less complex and more cost-effective consumer home networking solution. C.P. Clare is a participating member of the Home Phoneline Network Alliance (HomePNA), and its JackRabbit PHY transceiver interoperates with products conforming to the existing HomePNA 1Mbps specification while "turbocharging" up to speeds greater than 10Mbps.

At HomeNet '99, C.P. Clare will demonstrate a multiple PC network connected with JackRabbit PHY PCI bus cards over ordinary RJ-11 phone jacks and phone wire found in an estimated 100 million households and 20 million small businesses throughout the U.S. In addition, the PCs will be connected to a high speed Internet modem via the JackRabbit phoneline network, to demonstrate shared Internet services and video signal distribution at Ethernet (10Mbps) performance speeds.

"We developed this product with the consumer in mind and now we're demonstrating a solution that truly meets the performance and cost needs of the home networking market," said Doug Dillon, C.P. Clare's vice president of home network marketing. "The unique features of C.P. Clare's JackRabbit PHY transceiver allow networking, PC and PC peripheral OEMs to offer consumers low cost solutions that are easy to install and use at the speeds required to ensure optimal consumer satisfaction."
