has been in the VoIP (news

and the company has been educating the
market at TMC�s Internet Telephony
shows when others in the space went into seclusion. During this period,
the company was innovating. These investments paid off as now they have a
few new products that will further help the VoIP space.
Atlanta 100 is a RISC-based system on a chip or SOC (news -
- define) for short, which
supports up to eight voice channels for phone and fax and routing over
broadband connections, whether they be ADSL, cable, WiMAX (news
- define - tutorial), etc. Included
is a hardware reference design.
This customer premises equipment (CPE) product will
allow service providers to increase their revenue by giving consumers
toll-quality VoIP with features such as global phone number portability,
virtual phone numbers, iron clad security, echo cancellation and other
features you won�t find on the PSTN.
You will also find Caller ID, Japan Caller
Identification Protocol, call forwarding, call waiting, generic voice
activity detection, comfort noise generation (so you know the call is
still active), message waiting indicator, teleconferencing, call hold and
VoIP protocols supported are G.711 (PCM), G.729a/b,
G.726.32 and G.723.1. There is also support for Internet protocol
Security, (IPSec), Data Encryption Standard (DES), 3DES, and Advanced DES.
An OEM can add WiFi (news

Overall this is a robust chip and it shows that
semiconductor integration continues to engulf more and more functions that
used to require extra circuitry. This lowers cost, reduces electricity
needs (which means less heat dissipation) and typically increases MTBF.
The company has also developed the first gateway on a
chip named the Palladia 400, which will allow service providers to deploy
home gateways, IADs,
voice routers, and IP PBXs (news
- define - tutorial).
The chip-based gateway supports ADSL2/2+ and 2++. It
further offers a 200 MHZ MIPS processor and DSP designed specifically to
process VoIP. The device is designed for 50 Mbps downstream access! Let me
take a moment to ponder. Actually no, please allow me to beg. If any
service provider in the North East, specifically
is thinking about testing the rollout of 50 Mbps downstream DSL service,
PLEASE let me be the first beta tester. I even promise to write about it!
All in all, miniaturization of VoIP components is an
excellent thing as it lowers cost and makes it easier to develop new
products and of course increases competition. Centillium has shown that
they worked hard through the economic downturn and they are now around to
help service providers take advantage of the VoIP market as it continues
