Legerity Joins Forces with VoicePump on Advanced Reference Board Optimized for Packet-Voice Applications
Legerity's Am79R70 Ringing SLIC Provides Cost-Effective Line Interface for VoicePump's VP140 DSP-Based Solution for VoDSL and VoIP Equipment
AUSTIN, TX and PHOENIX, AZ — March 21, 2001 — Legerity, the proven communication IC company, today announced that it will provide ringing subscriber's line interface circuits (SLIC) for a voice over broadband (VoB) reference board developed by VoicePump, a DSP Group (NASDAQ: DSPG) subsidiary.
The advanced reference board -- which combines VoicePump's four-port VP140 mixed-signal digital signal processor (DSP) with four Legerity Am79R70 Ringing SLICs and other discrete devices -- will provide an integrated, turnkey solution that speeds the time to market and reduces the cost for voice over digital subscriber line (VoDSL), voice over Internet protocol (VoIP) and other packet-voice equipment. The reference board was announced at the Voice on the Net (VON) conference in Phoenix this week.
"Legerity has an expertise in voice communications and an established understanding of broadband networks," said Didier Boivin, chief executive officer at VoicePump. "Together, our companies can offer complementary technologies that provide optimized solutions for voice-over-broadband equipment manufacturers, allowing them to create cost-effective low- to medium-density voice gateways and integrated access devices (IADs)."
Legerity's Am79R70 Ringing SLIC is a high-voltage, bipolar device that supports on-chip ringing and battery switching for short-loop and "loopless" VoB applications, such as IADs. The Ringing SLIC's integrated capabilities minimize power consumption and help reduce system cost and component count by eliminating the need for separate, on-board generators and relays.
"VoicePump is among the industry's premier voice over broadband innovators, and we are very pleased that they have chosen our Ringing SLIC as an integral part of their VP140 DSP-based reference board," said Ron Van Dell, CEO of Legerity. "We consider VoicePump to be a strong ally in the race to deliver next-generation, toll-quality solutions for voice over broadband. Going forward, we hope that the combination of VoicePump and Legerity technologies will be a key enabler for broadband networks that leverage VoDSL and packet-voice applications."
The VP140-based board supports toll-quality voice and performs all voiceband processing required for VoDSL applications that comply with DSL Forum TR-036 Annex A Broadband Loop Emulation Services (BLES).
