Broadcom Enables iCable's Residential VoIP Multimedia Terminal Adapter

9/23/2003 - Broadcom Corporation (Nasdaq: BRCM), the leading provider of silicon solutions enabling broadband communications, announced that iCable System Co., Ltd has developed a residential VoIP (Voice over Internet Protocol) multimedia terminal adapter (MTA) based on the Broadcom® BCM1112 VoIP CPE engine chip and xChangeTM VoIP firmware.

iCable System is a leading developer of high-speed and multimedia Internet terminals in Korea. The company has incorporated Broadcom's VoIP technology into the ICS-G101, which is a standalone MTA supporting VoIP functions over all types of networks, including cable, ADSL and various Ethernet interface networking technology. The ICS-G101 is available in production quantities and is shipping to Hanaro Telecom in Korea and an incumbent telecommunications service provider in Japan.

"The level of integration and functionality we have achieved in the BCM1112 is enabling OEMs to develop complex terminal adapter products in remarkably short design cycles, with low risk and high-volume reliability," said Paul Shore, Director of Marketing for Broadcom's VoIP Client Products. "Residential VoIP deployments are accelerating rapidly in several parts of Asia, and we anticipate a similar expansion in North America starting in early 2004."

iCable's ICS-G101 features one analog POTS (Plain Old Telephone Set) port for connection to existing analog phones or fax machines, and additionally one PSTN (Public Switched Telephone Network) port. The products also include a Fast Ethernet switch and two physical Ethernet interfaces to support connection to a broadband DSL or cable modem and to a PC or home local area network (LAN).

"The high level of integration within the BCM1112, the field readiness of the xChange VoIP firmware, and Broadcom's excellent technical support collectively reduced the risk of our development program and helped ensure that we pass Hanaro's BMT (Bench Mark Test) for VoIP subscriber terminals," said Dr. Youngok Rhee, CTO of iCable System.

The ICS-G101 has been supplied to Hanaro Telecom via the model name of MTA2100 through Seoul Electron.

The BCM1112 features a 150 MHz MIPS32TM RISC processor and a powerful dual-MAC digital signal processor (DSP). The chip's Ethernet block includes an Ethernet switch and two integrated 10/100 Ethernet transceivers. Also integrated into the BCM1112 are three analog CODECs capable of supporting both narrowband (8 kHz) and wideband (16 kHz) sampling. These CODECs, in conjunction with wideband vocoders such as the Broadcom BroadVoice32TM, will enable IP networks to deliver higher fidelity voice quality than the traditional PSTN in the future. The xChange VoIP firmware that runs on the chip offers all of the common high-level protocol stacks popular today (SIP, H.323, MGCP, H.248/Megaco), as well as voice-band processing algorithms (variety of vocoders, line echo canceller, call processing tone generation, fax relay, etc.) required to enable customers to bring products to market extremely quickly.
