Rim Semiconductor Achieves Best-in-Class Data Speed on Copper Wire

First Implementation of IPSL draft 1.0 Achieves Goal
PORTLAND, Ore.--(Business Wire)--Rim Semiconductor Company (OTCBB:RSMI) announced today that it has
achieved best-in-class data speed on copper wire. The company's draft
Release 1.0 of the Internet Protocol Subscriber Line(TM) specification
calls for a semiconductor to drive data at fiber-like speeds over the
existing copper telephone lines. In line with the draft specification,
Rim Semi's Cupria(TM) transport processor is now able to drive data
traffic at 40 megabits per second (Mpbs) 5,500 feet (1.67km) on 26AWG
(0.40mm) telephone wire. Existing technologies are able to drive data
15 mbps at this distance on this wire type.

IPSL(TM) draft 1.0 is designed to be more appropriate for advanced
telephone network services like internet protocol television (IPTV)
than existing DSL technologies are. Rim Semi is the first company to
build IPSL draft 1.0-compliant semiconductors for inclusion in a
variety of telecommunications equipment products. The company 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.

"We are delighted that we are able to meet the demanding
specification of IPSL," stated Brad Ketch, president and chief
executive officer of Rim Semiconductor. "Our technical team will
continue to push the boundaries of data transmission across copper
wire because 1.4 billion existing copper-based end users require it."
