Agilent Technologies Teams With Zoom Telephonics On Automated Cable Modem Test Suite to Speed DOCSIS Certification

PALO ALTO, Calif., March 20, 2000 -- Agilent Technologies Inc. (NYSE: A) announced today that it has teamed with Zoom Telephonics Inc., (NASDAQ: ZOOM) to develop an advanced, automated test suite that speeds standards certification of Zoom's cable modems. The new system is expected to reduce the time required for Zoom to deliver new cable modem designs to market by enabling pre-testing of its products for standards compliance before they are submitted to Cable Television Laboratories, Inc. (CableLabs) for DOCSIS (data over cable service interface specification) certification.

DOCSIS interoperability standards, developed by CableLabs, define interface requirements for cable modems supporting high-speed data distribution over broadband cable TV networks. DOCSIS certification ensures that cable modems will work properly with similarly certified head end equipment from any manufacturer, and is widely viewed as a requirement for success in this growing marketplace.

CableLabs, a research and development consortium of cable television system operators, is the primary third-party industry laboratory responsible for testing and providing DOCSIS product certification. As part of the certification process, suppliers must complete self-testing of their products at their own facilities, prior to submission to CableLabs, and products must also be evaluated by multiple cable system operators.

"The DOCSIS certification process is among the most rigorous of any in the communications industry," said Peter Shaw, marketing manager for Agilent's Service Test Division. "Our work with Zoom and other companies in the cable industry who will provide key elements required for deployment of interactive cable services reflects Agilent's growing involvement in all aspects of deployment of broadband cable services."

The test solution provides complete PHY/MAC (physical/media access control) design verification of RFI/PICS/ATP and a documentation package of test results for submission to CableLabs. Use of the test suite is expected to improve Zoom's ability to deliver new cable modem designs by automating tests used in both R&D (research and development) and production. Zoom believes the test system will allow earlier introductions of new feature sets and new cost-effective designs.

"These new tools from Agilent dramatically improve our ability to engineer and test our cable modems to the demanding standards of CableLabs," said Frank Manning, president of Zoom Telephonics. "Zoom was the first company to embrace this advanced test-automation technology, and to partner with Agilent to develop and implement these systems. We believe they will play an important role in establishing Zoom as a leader in cable modem design."
