Toshiba Enterprise IP Phones Ship with Broadcom BCM1113 Chip

11/12/2004 - Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, announced that the Broadcom® BCM1113 Internet Protocol (IP) phone chip is now shipping as a standard offering in Toshiba's IPT1020-SD enterprise IP telephones. The BCM1113 IP phone chip is designed for a wide variety of enterprise IP phones, which allow people to transmit and receive voice calls over the Internet using an Ethernet LAN connection in the office.

The integrated Ethernet switch (two port) capability in the BCM1113 enables manufacturers to develop IP phones that use the Ethernet switch connections of the IP Phone to support both voice calls through the phone and data traffic to the PC. This capability offers significant cost savings to businesses by eliminating the need to have two Ethernet connections in an office or to add switch ports in the wiring closet to support VoIP. As a result, the BCM1113 chip enabled Toshiba to offer an economical, high- performance IP phone solution to its customers and expand its enterprise Strata CTX digital business communication system product portfolio.

The IPT1020-SD IP phone is a key component of the Strata CTX system because it enables remote users to enjoy the same productivity features as those on the main office telephone network. The IPT1020-SD offers customers extension-to-extension dialing, busy lamp field (BLF) station status display, paging over telephone speakers, off-hook call announce over the telephone handset, voice mail and many other advanced telephony features.

"We are pleased to announce that our IP phone chip is now shipping as a standard component within Toshiba's Strata CTX enterprise IP phones, which is a significant milestone for Broadcom since Toshiba is recognized in the industry as an experienced, long-time enterprise telephony equipment company," said Paul Shore, Broadcom's Director of VoIP Client Products. "Our relationship with Toshiba is yet another example of how industry leaders are looking to Broadcom to provide them with innovative, high-quality voice IP solutions to support the transition from time-division multiplexing (TDM) to VoIP network services."

"Broadcom's feature-rich devices and outstanding technical support have enabled us to quickly and efficiently bring new cost-effective enterprise IP phones to market," said Kiyoshi Ishikawa, Senior Manager of Business Communication System Department, Toshiba. "The chip's high level of silicon integration and the proven reliability of the VoIP firmware package that operates on the chip have significantly reduced the development complexity and risk of our new IP phone programs."

Technical Background
The BCM1113 features a MIPS32® RISC processor to support advanced computer telephony integration (CTI) applications, and a powerful dual-MAC digital signal processor (DSP). The chip's integrated Ethernet MACs and wire-speed non-blocking 10/100 Ethernet switch support IEEE 802.1p packet prioritization and 802.1Q VLAN identification. Also integrated in the BCM1113 are analog CODECs capable of supporting both narrowband 8 Kilohertz (KHz) and wideband 16 KHz sampling, which in conjunction with wideband voice coders, such as the Broadcom® BroadVoice32TM coder, will enable IP phone networks to deliver high-fidelity voice transmission. The Ethernet transceivers are designed and tested to withstand 2000 volts of cable-sourced electrostatic discharge (CESD), which prevents the system from being damaged or destroyed due to electric discharge during installation and cable insertion.
