ADSL has arrived? Read on:
LARGO, Fla., June 3 /PRNewswire/ via Individual Inc. -- AT&T Paradyne has announced an industry breakthrough that will soon enable customers worldwide
to have much faster Internet access, with simultaneous voice service on a single telephone line. The new GlobeSpan(TM) Rate Adaptive Digital Subscriber
Line (RADSL) technology increases data throughput up to 400 times faster than a 14.4 Kbps modem, using existing copper phone lines. Telecom equipment
manufacturers are currently licensing GlobeSpan RADSL technology as the basis for their new generation of high-speed products for Internet access and
other data services.
With the dramatic speed advantage offered by GlobeSpan RADSL technology, users can finally enjoy the World Wide Web -- without the wait. Web site
graphics that would require six minutes to display using a 14.4 modem could appear in less than one second with RADSL products. GlobeSpan RADSL delivers
the highest possible performance over standard phone lines, with downstream rates of 600 Kbps to 7 Mbps, and upstream return rates of 128 Kbps to 1
Mbps.
GlobeSpan RADSL technology is a significant advancement over other DSL implementations because its transmission speed is rate adaptive based on the
length and signal quality of an existing telephone line. RADSL products will have the option to select the highest practical operating speed
automatically or as specified by the telecom service provider. This variable rate feature ensures high quality service to all customers, even those
residing a long distance from the telephone company's nearest equipment location.
Another key advantage provided by GlobeSpan RADSL technology is its ability to allow telephone conversations and data transfer simultaneously over a
single phone line. Concurrent use of the same phone line delivers considerable savings and convenience for end users. For example, a telecommuter can
log-on to a corporate network from home and remotely edit a document while discussing the changes with a colleague on the same phone line. Likewise, one
member of a household can use the family phone line to surf the Internet, while another family member uses the same line for a telephone call. RADSL
also provides a practical solution for retaining telephone service when house electrical power is interrupted.
"We wanted to develop a flexible and low-cost technology that enables telcos and Internet Service Providers to meet the growing demands of their
customers for fast Internet access," said Gabe Torok, general manager of Paradyne's Advanced Transmission Technology Unit. "The Internet is at a
critical turning point. People realize the incredible potential of the Internet and the World Wide Web, yet many have dubbed it the 'World Wide Waste of
Time.' They're simply tired of waiting ... and waiting ... and waiting for graphically intense Web pages to materialize on their screens."
Clete Gardenhour, director of business development expanded on the Paradyne solution, adding that, "GlobeSpan RADSL technology puts an end to the World
Wide Wait, bringing back the excitement that brought residential users to the Web in the first place. It also allows business users to realize effective
use of the Internet and Intranets for practical applications by minimizing network access delays."
Benefits of GlobeSpan RADSL Technology for Telcos and Telecom
Equipment Providers
Paradyne's GlobeSpan technology provides the fastest, most reliable solution for telcos and PTTs to provision RADSL access on their existing networks.
With GlobeSpan technology, RADSL products can be provisioned on a great majority of telephone lines without costly and time-consuming network upgrades.
GlobeSpan technology will enable telephone companies to satisfy current market demand immediately, while also protecting their installed customer base
against other access providers (cable TV, satellite and wireless) who plan to offer Internet and Intranet services in the future.
RADSL is a flexible technology implementation that utilizes the powerful transmission characteristics of both ADSL and SDSL (Asymmetric and Symmetric
Digital Subscriber Line) technologies. By using the best of both, RADSL enables optimization of data transfer rates by application and ensures high
quality transmission over longer distances.
Its variable rate capability offers significant savings for equipment manufacturers who can sell one DSL product to support a range of data rates, with
both symmetric and asymmetric transmission modes. In addition, GlobeSpan RADSL transceiver technology allows denser packaging and consumes less power
than alternative ADSL technologies. The new cost-effective generation of GlobeSpan RADSL products will reduce complexity and lower expenses for
equipment manufacturers, telcos and Internet Service Providers, thus ultimately benefiting residential and small office users who want reliable,
high-speed Internet access.
Availability of the Industry's First Rate Adaptive DSL Technology
Continuing its long-standing leadership role in the DSL market, Paradyne is the first technology provider to offer licensing rights to its Rate Adaptive
DSL solutions. GlobeSpan RADSL is a fully integrated solution for high-speed data access with simultaneous telephone service on the same phone line. In
addition, GlobeSpan RADSL technology is based on reliable, low-power, field-proven VLSI devices that are in volume production and are also used in
GlobeSpan HDSL, ADSL, and SDSL transceiver designs.
Initial availability (with downstream data rates up to 2.3 Mbps and upstream data rates up to 1 Mbps) is scheduled for August 1996. The full range of
automatic rate adaptive speeds (up to 7 Mbps downstream) will be available in November 1996.
