Reducing chips from designs lowers cost, reduces failure rates, reduces electricity usage and heat dissipation. Most importantly it reduces cost. This is especially true when you are eliminating a DSP.


The production version of a VoIP Analog Telephone Adapter (ATA) module

is the first without a DSP chip.

SANTA BARBARA, Calif., March 2, 2005….. D2 Technologies, Inc. and Alpha Networks, Inc. (Hsinchu, Taiwan) announce the availability of the first production version of a VoIP Analog Telephone Adapter (ATA), incorporating a MIPS-based processor chip, with embedded D2 VoIP software, without use of a DSP chip.

Traditional ATAs incorporate a DSP chip/core or special ASIC for voice processing functions like echo cancellation, voice compression, tone detection/ generation, etc.  However, D2's vPort software implements the voice functions as a "softDSP" on the MIPS processor. vPort is a complete VoIP software solution, which integrates the soft-DSP with voice signaling, packetizing, jitter smoothing, networking and telephony drivers needed in the ATA applicatio n.

The Ideal VoIP ATA for the Residential Market

 "This ATA is targeted at the residential market where telcos and service providers are aggressively deploying voice services over broadband," says David Wong, president of D2. "In addition to unlimited toll-free calls, VoIP will enable a cornucopia of new and exciting services, such as follow-me, international roaming, call management, data integration, multi-party conferencing etc. to be easily available to the subscriber. I think we are, finally, seeing the final days of the plain old telephone service, and the dawn of a new generation of IP communications services."

VoIP functionality includes: G.711, G.726, G.729AB voice compression, voice activity detection, packet loss compensation, silence compression (SID), G.168-2000 line echo cancellation, DTMF detection/generation/relay, call progress tone generation, fax/modem tone detection for fax pass-through or T.38 fax relay, three-way calling, dynamic/adaptive jitter buffer manager, RTP/UDP/IP and an embedded SIP call control stack.

"The combination of D2's voice technology and field-proven software, and Alpha's networking capability," notes Thomas Huang, vp Broadband of Alpha Networks, "has resulted in the development of a product that meets the demanding real-time requirements necessary for voice processing in packet network environments. This partnership has made it possible produce a low-cost VoIP ATA in a very small package because of Alpha's design and manufacturing expertise."
The Alpha device (ATA1001) is only 7.5 cm x 8 cm (approximately 3 inches x 3.2 inches). It has one RJ-11 port for the attachment of a standard telephone, and one RJ-45 port for connecting to a broadband/WAN device.
The ATA1001 is available beginning in March 2005.
