IPSL SPECIAL INTEREST GROUP™ AND
RIM SEMICONDUCTOR ANNOUNCE MEETING

Industry Group to Meet in Milan in to Accelerate
Adoption of New Specification for Video Over Broadband
and to Recruit European Members.

PORTLAND, OR and SUNNYVALE, CA: October 31, 2007: The IPSL Special Interest Group and Rim Semiconductor Company today announced that the IPSL SIG™ will conduct its Fall 2007 meeting in Milan, Italy. Pirelli Broadband Solutions will serve as host for the meeting. The principle agenda item will be consideration of draft Release 1.0 of the Internet Protocol Subscriber Line™ specification.

The IPSL SIG™ is targeting its Spring 2008 meeting at a location in Asia that will be announced later.

IPSL™ 1.0 allows data speeds as high as 384 megabits per second (Mpbs), versus 100 mbps for the nearest similar technology, VDSL2. IPSL 1.0 also specifies data speeds of up to 35 mbps at distances that are as far as 8,000 feet from the nearest telephone company facility. This reach is designed to be more appropriate for advanced telephone network services like internet protocol television (IPTV) than existing DSL technologies are.

Rim Semiconductor Company is the first company to build IPSL 1.0-compliant semiconductors for inclusion in a variety of telecommunications equipment products. Rim Semi has used its patented and patent-pending technologies to enhance data protocols, modulation schemes, noise reduction algorithms and other core technologies that together achieve results that are far better than existing technologies. The Company is demonstrating IPSL 1.0 to telephone companies and to equipment makers in several countries now.
