Diamond Lane Publishes Free ADSL CAP Framer Tool Kit
Moves Supports CAP Interoperability
PETALUMA, Calif.--(BUSINESS WIRE)--Feb. 11, 1998--Diamond Lane Communications, a technology leader in high-speed xDSL access systems, announced today it is publishing a free software license and designer's tool kit for its CAP framer's VHDL implementation, the first step in supporting future interoperability work using the Globespan CAP (Carrierless Amplitude and Phase Modulation) ADSL line interface.

''We wholly support the need for open, interoperable xDSL interfaces in the marketplace, no matter what line code or modulation technique is used. By making available our framer, we hope to encourage those companies deploying or planning to deploy CAP ADSL (Asymmetric Digital Subscriber Line) to work toward the development of an open interface,'' says Dr. George Hawley, President and Co-founder of Diamond Lane.

The free Diamond Lane CAP framing algorithm is the result of the company's active participation in the T1E1.4 CAP/QAM ad hoc working group which recently drafted letter ballot 653 to encourage CAP standardization among ADSL equipment companies. T1E1.4 functions as a unit of the T1 Committee which is sanctioned by ANSI (American National Standards Institute).

Included in the tool kit is a free software license, Diamond Lane's field-proven VHDL code and supporting documentation.

According to Hawley, the Diamond Lane design kit implements a frame and ''EOC'' design agreed upon by many ADSL industry members during the development of the recent CAP letter ballot interface proposal.

This interface format provides a separate ''EOC'' (Embedded Operations Channel) for communication of line-related management information between the Central Office DSLAM and the customer's ADSL modem to separate network provider line maintenance and management functions from service provider and corporate ATM payload management information. This payload independent framing and ''EOC'' design follows the general principles used in other transmission line interface standards such as DS1 and ISDN basic rate.

Diamond Lane is also developing a standard T1.413 DMT (Discrete Multitone) version of ADSL, as well as other DSL line interfaces in response to varying customer needs in the marketplace. Both CAP and DMT are offered for ''splitterless'' operation at the end user premises to support customer ''Plug-In DSL'' and to save installation expenses.

In September Diamond Lane shipped the first commercial, Bellcore verified NEBS compliant xDSL product: The SpeedLink(TM) system consists of a Digital Subscriber Line Access Multiplexer (DSLAM) using state-of-the-art ADSL-ATM-to-the-desktop (Asynchronous Transfer Mode) technology. SpeedLink CAP ADSL enables private and corporate PC users to download large files from the Internet at up to 6.2 Mbps, 200 times faster than with conventional modems. It is now in commercial use by Silicon Valley corporate telecommuters and New England power users.

Diamond Lane Communications Corporation, founded in 1995, is one of the first companies in the world to commercially offer DSL (Digital Subscriber Line) data access. Privately held, the company is a worldwide technology leader in xDSL solutions, enabling a variety of high-speed data applications via its SpeedLink(TM) system, a DSLAM (Digital Subscriber Line Access Multiplexer) based on ATM standards. Its mission is to enable network and service providers to offer today's NetSet power users, corporate telecommuters and small businesses economical, high-speed access to the Internet, as well as other data services.
