Broadcom's Chips Continue To Lead Industry In Cable Modem Customer Certification

CableLabsÆ Certifies Cable Modems From Com21, GI And RCA, Re-Qualifies Cisco CMTS

Broadcom Corporation (Nasdaq: BRCM), a leading provider of integrated circuits enabling broadband communications to and throughout the home and business, announced Friday that the recently CableLabsÆ Certifiedô Data Over Cable Service Interface Specification (DOCSIS) cable modems from Com21, General Instrument and Thomson Multimedia's RCA Broadband Cable Group (RCA), and re-qualified cable modem termination system (CMTS) from Cisco Systems, are all based on Broadcom's cable modem chip technology. The CableLabsÆ Certifiedô seal indicates to consumers and cable operators that the cable modem complies with the DOCSIS standard, which was developed to ensure the availability of interoperable cable modems from multiple vendors at retail prices. Earlier in the year, 3Com Corporation, Arris Interactive (majority owned by Nortel Networks), Askey Computer Corporation, Cisco Systems, General Instrument, Philips Broadband Networks, Samsung Electronics and Thomson Consumer Electronics received the CableLabs Certified seal, and Arris Interactive, Cisco Systems and Motorola received CableLabs certification for their cable modem termination systems. All of these companies also use Broadcom's cable modem chips. Broadcom has been a principal contributor to the DOCSIS standards development efforts since the project began almost two years ago, and continues to author backwards-compatible, next-generation features to advance the standard to support new Internet Protocol (IP) services. CableLabs established the DOCSIS standards and certification process to allow equipment designed to common specifications to work in any cable network, with the ability to extend the standard to support future upgrades and services, such as IP telephony, increased Internet security, and video teleconferencing. The recently certified products use the BroadcomÆ BCM3300 chip. The BCM3300, announced in September 1998, was the world's first DOCSIS-compliant single chip modem. Broadcom's QAMLinkÆ chips are used in cable modems, cable headends, set-top boxes and other broadband consumer devices worldwide. The company's DOCSIS 1.0 and 1.1 standards compliant chips incorporate all of the basic media access control (MAC), physical layer transmission, computational resources and peripherals necessary for robust broadband connectivity and provide support for encryption, multicast filtering and Quality of Service capabilities for low cost, reliable telephony and data services.
