Reference Designs Provide Hardware/Software Solutions for Delivery of

IP Telephony, High-Speed, "Always-On" Internet Access and Home

Networking Services

Broadcom Corporation (Nasdaq:BRCM), the leading provider of integrated circuits enabling broadband communications, today introduced the industry's most comprehensive, lowest-power, and feature-rich VoIP/Home Networking PacketCable(TM) reference designs for residential broadband gateways. These gateways enable entire new classes of consumer services and applications, from basic phone service to new household information appliances.

These complete reference designs, the Broadcom(R) BCM93352V and BCM93352VCM, are based upon Broadcom's BCM3352 VoIP/home networking residential broadband gateway chip and include all required hardware, plus Broadcom's DOCSIS 1.1 and CablexChange(TM) PacketCable software, to greatly accelerate manufacturers' development of next-generation cable modem residential broadband gateways. The BCM93352V is an ultra low-power, outdoor residential gateway, providing up to four-primary lines of Voice over Internet Protocol (VoIP) telephony, while the BCM93352VCM is a two-line, low-cost indoor VoIP cable modem gateway design. Using these designs, manufacturers can customize their products to address the full spectrum of cable modem gateway markets, including multi-dwelling units (MDUs).

"We are announcing two new reference designs based on the most highly integrated and lowest power single-chip VoIP DOCSIS Cable Modem, the BCM3352," said John Gleiter, Broadcom's Product Line Manager of Packet Telephony. "Manufacturers now have access to the most comprehensive two- and four-telephone line gateway reference designs available, integrating superior hardware with the industry's most flexible VoIP and DOCSIS 1.1 software."

The BCM93352V is a four-channel VoIP/home networking outdoor reference design that is delivered complete with all hardware and software required to develop a low-power VoIP gateway that meets industry-standard PacketCable specifications for operation in outdoor environmental extremes. In addition, the BCM93352V includes an integral high-efficiency switching power supply that can be powered directly off a hybrid fiber coax (HFC) cable network, or an uninterruptible power supply (UPS), providing a complete solution for demanding primary-line services. Primary line (911) service requires that the cable network, or UPS, power the VoIP gateway so that telephone service can be ensured in a power-out condition.

Other features of the BCM93352V include integrated home phone line networking, based on the HomePNA 2.0 universal worldwide standard. HomePNA 2.0 provides the lowest cost and most reliable method for networking communication devices in the home. Recently incorporated into consumer PC's and web appliances by Gateway Computer to power its "Connected Home," Broadcom's HomePNA 2.0 technology acts as a low-cost, robust, high-speed broadband communications backbone to which wireless, power line, and wire-line extension devices attach.

The BCM93352VCM is a reference design that addresses the two-line VoIP cable modem market. Many operators, both in the U.S. and overseas, do not have the need to provide primary-line service, but want to offer their customers a very cost-competitive second-line service for VoIP telephony and home networking. The BCM93352VCM provides a low-cost, commercial grade reference design with USB 1.1, 10/100 Ethernet and HomePNA 2.0 interfaces. This product is also supplied with Broadcom's DOCSIS 1.1 and CablexChange VoIP software, providing a well-designed solution for the low-cost VoIP cable modem market.

Both reference designs are based on Broadcom's leading CablexChange family of VoIP software, which is the industry's most complete, flexible and efficient PacketCable software solution, providing users with the only OpenVoIP(TM) architecture available. Broadcom's xChange VoIP software allows users to optimize cost and performance tradeoffs between the Central Processing Unit (CPU) and Digital Signal Processing (DSP) resources for each product and system architecture.

Unlike other DSP-centric solutions that require large amounts of expensive DSP MIPS and memory, Broadcom's xChange family of flexible OpenVoIP software translates to lower product costs and reduced power consumption. Field-proven over years of operation in "mission critical" carrier access applications, xChange provides highly reliable, open IP telephony software solutions. Unlike proprietary, closed systems, Broadcom provides a straightforward set of published Application Programming Interfaces (API's), providing customers with the ability to differentiate and add value to their products.

The BCM93352V and BCM93352VCM are available today.
