MOTOROLA ANNOUNCES COPPERGOLDTM ADSL
TRANSCEIVER WITH ADAPTIVE RATE MODE
Standards-Based Solution Enables End Users to Receive Fastest Access to
Services Available, Providing Telcos with a Competitive Advantage
Technology to be Featured at Supercomm, Booth #3270
Austin, TX - June 11, 1996 - Motorola's (NYSE: MOT) MOS Digital-Analog Integrated Circuit
Division (MDAD) today announced an industry-leading solution for telcos entering the highly
competitive interactive multimedia services market. Called CopperGoldTM (part # MC145650), this
Discrete Multi-Tone (DMT)-based Asymmetric Digital Subscriber Line (ADSL) transceiver has an
adaptive rate mode which ensures that end users receive the highest data throughput - and therefore the
fastest access to multimedia services - possible. In the competitive communications environment, the
service provider which can provide quickest access has a strong competitive advantage. The Motorola
CopperGold transceiver will enable up to 600 times the data rate of a 14.4 analog modem, using existing
copper phone lines.
How CopperGold Works
Motorola's CopperGold ADSL transceiver gives telcos flexibility through implementation of several
modes of operation including, but not limited to, ATM and Rate Adaptive Mode. During initialization, the
CopperGold transceiver can be configured through the host processor interface as an adaptive rate
modem that can adjust the data rate to within 32kbps of the maximum throughput the line is capable of
supporting. Upon line start-up of the rate adaptive DSL (RADSL) mode, CopperGold determines the
line condition and transport capacity of each specific line, and then operates at the best data rate possible
for each line. Alternatively, the telco can predetermine the rate. Data rates are from 64kbps to 1.0mbps
bidirectional, 32kbps to 8mbps downstream.
The key behind this technology is the DMT standard developed by Amati, endorsed by ANSI
T1.413-1995 and adopted by Motorola in the development of a single chip transceiver. The advantage of
DMT-based RADSL is that it is not optimized for only one loop but dynamically optimizes to each loop
for the greatest throughput available. Rate adaptive capability was built into the DMT standard originally
and is now recognized as a key to the business case for ADSL deployment for internet access and
on-line services.
Key Advantages
Motorola's CopperGold transceiver is highly integrated into a single chip solution to achieve the lowest
cost while maintaining high performance. An additional advantage of the CopperGold ADSL transceiver
is that it operates with low power consumption, using approximately 1/3 of the power of today's
systems.
A home receiving ADSL-based services could simultaneously be viewing up to four movies stored in
MPEG1 format and transmitted at 1.5 Mbps on separate televisions, while holding a video conference
utilizing 384 kbps, and downloading data files from a server at work utilizing 128 kbps via ISDN. A
telephone call from a neighbor could also be received without disturbing the other activities.

"Future Proof"
In a still-uncertain market, where it is not yet clear which broadband services will be in most demand
from the end users, Motorola's CopperGold solution empowers telcos with the ability to incorporate new
services as they reach critical demand. Capable of supporting today's broadband access via plain old
telephone service (POTS) lines, CopperGold also allows for the addition of tomorrow's advanced
services such as videoconferencing, VOD and interactive multimedia. Motorola's CopperGold
transceiver will be available in early 1997.
"CopperGold is a true revolution for the communications industry,"said Debbie Sallee, ADSL Business
Development Manager for Motorola's MOS Digital-Analog IC Division. "Its adaptive rate capabilities,
low power consumption, and single-chip, low-cost design combine to provide telcos with a powerful and
cost-effective means of delivering the multimedia services consumers demand."
Motorola will be featuring ADSL Internet access technology at their Supercomm Booth (#3270), June
23-27, in Dallas. For more information on the CopperGold ADSL transceiver, visit Motorola's web site
