Legerity Unveils VoiceChip Family of Voice over Broadband - VoB - Semiconductors.Business Editors and High-Tech Writers
AUSTIN, Texas--(BUSINESS WIRE)--Nov. 4, 2002
Legerity's VoiceChip Voice Interface Solutions Offer Fastest,
Simplest, Least Expensive Way to Connect Telephones to Cable
and DSL Modems
Legerity, the world's leading provider of voice interface integrated circuits Integrated circuits
Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (ICs), today introduced a new family of voice ICs specifically designed to enable connection of telephone lines to DSL DSL

The VoiceChip(tm) family includes new and updated telephone subscriber line interface circuits (SLICs) and integrated chipsets -- all sharing common interfaces, compatibility with worldwide standards and unique features specific to VoB. VoiceChip family devices support the connection of one to eight telephone lines.
"By introducing the new VoiceChip family, Legerity is making a significant contribution to help facilitate the deployment of voice over broadband technology," said Teresa Mastrangelo, program director for the Broadband Access Networks: Global program at RHK RHK Ratahallintokeskus (Finnish: Finnish Rail Administration)

IC vendors that introduce new technology that makes it easier and more cost-effective to develop and deploy VoB equipment will help drive the voice over broadband industry forward."
VoiceChip solutions make it practical to add voice to a wide range of broadband applications, including cable and DSL modems, integrated access devices (IADs), network interface units (NIUs), set-top and house-side boxes, voice over ISDN ISDN

VoiceChip solutions are also a good fit for emerging fiber to the home (FTTH (Fiber To The Home) See FTTP. ), ATM passive optical network (APON See PON. ), next-generation network (NGN (Next Generation Networks) An umbrella term for mixed voice and data networks running over the IP protocol. See IP Multimedia Subsystem. ) and other voice over IP (VoIP) applications, such as Yahoo! BB (Broadband) VoIP service in Japan.
Using VoiceChip IC products, customer premises equipment (CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises.

"The expansion of the worldwide VoB market, now standing at more than 12 million subscribers and growing at more than 30 percent a year, calls for voice interface solutions that make it fast, easy and cost-effective to add voice capabilities to broadband access equipment," said Eric Broockman, vice president of marketing at Legerity. "Legerity puts more than 20 years of voice experience into every VoiceChip IC, and the family's interface-compatible framework future-proofs our customers' VoB system designs by offering them a lot of options for where they take their forthcoming products."
Unique VoiceChip product features include:
-- Software programmable to operate in more than 100
countries ("one design fits all")
-- Interoperable with popular DSPs and network processors -- SLIC devices built with Legerity's proprietary, patented deep-trench high-voltage bipolar process designed to enable optimal voice performance at the lowest cost -- Integrated test features (similar to those used by telephone service providers) enabling remote diagnostics of telephone sets and lines by broadband network service providers
VoiceChip family members support a variety of integrated features essential for VoB applications, including on-chip ringing, modem tone detection, caller ID support and automatic battery switching or optional on-chip switching regulators (to generate high-voltage ringing battery). This high level of integration minimizes discrete component count, increases board density and reduces power requirements, resulting in lower system cost and simpler designs.
Major VoiceChip product categories include:
-- Programmable voice codec ICs - one- to eight-channel
DSP-based codecs The following is a list of codecs. Audio codecs
-- Ringing SLIC SLIC Subscriber Line Interface Circuit
SLIC Scottish Library and Information Council
SLIC System Licensed Internal Code
SLIC Subscriber Line Interface Card
SLIC Session Layer Interface Card (Alacritech, Inc. ICs - single- and dual-channel subscriber
line interface circuits
-- Integrated VoB chipsets - highly programmable one- to
four-channel SLIC/codec chipsets
The VoiceChip family is backed by Legerity's worldwide direct sales organization and field applications support network. The family is also supported by Legerity's comprehensive suite of design tools, including the VoicePath(tm) software development kit and more than 25 unique line modules, reference designs and evaluation boards developed by Legerity and many of the world's leading data chipset suppliers. Using these Legerity development tools, VoB design engineers can shorten their development schedules and reduce time to market by several months.
Legerity will introduce new VoiceChip products and reference designs over the coming months, including several VoiceChip family-compatible versions of voice ICs from Agere Systems' Voice Interface Solutions business, which Legerity acquired in late Q3 of this year.
