Mindspeed Adds Major Enhancements to LoopWizard Diagnostic Software for More Efficient and Cost-Effective DSL Deployment.

New Broadband Noise Measurement Feature Delivers More Line Testing Capabilities for Mindspeed's ZipWireMulti DSL Chips -- Eliminating the

Need for External Test Equipment

Mindspeed Technologies(TM), the Internet infrastructure business of Conexant Systems, Inc. (Nasdaq:CNXT), today announced significant enhancements to LoopWizard(TM), delivering broadband noise measurement technology in the latest installment of sophisticated diagnostic software that runs on Mindspeed's ZipWireMulti(TM) octal symmetrical high-bit-rate digital subscriber line (G.SHDSL) transceiver silicon.

The broadband noise measurement capability follows LoopWizard's groundbreaking Sequence Time Domain Reflectometry (STDR) technology, introduced earlier this year, which was the industry's first line-testing technology integrated into a DSL chip.

Delivering on LoopWizard's promise of a wide range of diagnostic features, the broadband noise measurement software performs the function of a high-end spectrum analyzer as well as of a traditional transmission noise measurement system.

These noise and spectrum measurements can be used to estimate the capabilities of a copper loop prior to deployment and to determine the cause of subsequent connection failures.

Key to Successful Deployment

LoopWizard software is an integral part of Mindspeed's multi-mode G.SHDSL solution for business-class applications that provide diagnostic technology embedded in its transceiver silicon, eliminating the need for expensive external test boxes and switching systems. By taking advantage of the loop test technology built into the DSL chips, operators can enjoy tremendous cost savings as well as increased reliability.

Large carriers are often unable to deploy loop testing on a scale required for a typical large city central office, as the amount of switching and test equipment required for such a vast number of lines would be prohibitively expensive. With LoopWizard, every port is a test head, resulting in an infinitely scalable solution.

LoopWizard is also one of the few practical test solutions available to carriers as they deploy DSL via unmanned remote terminals or Digital Loop Carrier (DLC) equipment. DSLAM manufacturers can now offer enhanced capabilities including sophisticated pre-qualification of lines and automated disaster recovery. "Smart DSLAMs" can now report outages along with details of why they have occurred.

"This latest installment of LoopWizard technology continues to deliver on the promise of efficiency, cost savings, and ease of DSL deployment that Mindspeed inaugurated with the simple -- yet revolutionary -- concept of sophisticated diagnostic capabilities built right into the silicon at the heart of a DSLAM," said Tom Kovanic, vice president of marketing with Mindspeed.

"The benefits to the industry are far reaching, providing more intelligent DSL equipment, more manageable and less costly DSL deployment, and, ultimately, better DSL service for everyone."

Technical Details

LoopWizard's latest offering performs the core functions of a broadband test head and implements them as broadband noise measurement software running on Mindspeed's RISC-based CX28985 ZipWireMulti chipset. This eliminates the need for external test equipment and the associated relay matrices required with conventional solutions in order to temporarily switch the line through a cross-connect during testing.

The broadband noise measurement capability emulates two separate test systems: a spectrum analyzer and a transmission noise measurement system. As a spectrum analyzer, the software outputs a spectral plot with a maximum bandwidth from 7 KHz (limited by the line transformer selected) to 850 KHz with the ability to output the average of a user-selectable number of scans and measurement bandwidth.

The measured spectrum data is stored in a format that is compatible with most Agilent(TM) spectrum analyzers, allowing users to employ a wide range of commercially available analysis tools. Mindspeed also provides powerful analysis and stimulus software for every LoopWizard feature.

Additional capabilities of broadband noise measurement software include fixed-filter energy measurements such as those found in conventional telephone test equipment, user-definable filters, and additional features. Fixed-filter measurements allow rapid and reliable correlation to noise measurements previously made with traditional transmission noise test sets.

Like all LoopWizard capabilities, this second offering allows diagnostic test to be conducted on any port of any chip at any time regardless of the status of any other port or chipset.

The broadband noise measurement software takes advantage of the RISC processor integrated into the CX28985 chipset without any of the hardware modification needed for standard G.SHDSL operation. A manufacturer simply enters a Mindspeed authorization code via an API command during the chipset's initialization.

LoopWizard can be easily integrated into previously designed CX28985-based products as well as into new ones, giving OEMs a wide range of choices for system features, options, and enhancements. The CX28985 chipset also has the versatility to accommodate multiple protocols. It offers G.SHDSL, HDSL2, HDSL, IDSL, or STDR in any mix on any port at any time.

In all cases, the external circuitry remains fixed and unchanged.

Future LoopWizard offerings will include additional diagnostic capabilities, such as impulse noise, crosstalk analysis, DC measurements, and others, further reducing the cost of deploying and operating successful DSL service.

Pricing and Availability

LoopWizard's broadband noise measurement software is available immediately for use with Mindspeed's CX28985 ZipWireMulti eight-port G.SHDSL chipset. The CX28985 is priced at $160 per unit in OEM volumes of 10,000. LoopWizard is available for a one-time license fee on a per-product basis, permitting unlimited use and distribution as an integrated feature on Mindspeed devices.
