Centillium Communications introduced an ADSL2+/2++ and VoIP gateway-on-a-chip for next-generation Customer Premises Equipment (CPE). The new Palladia 400 chip uses Centillium’s eXtremeDSLMAX technology for downstream rates up to 50 Mbps. It offers an integrated 200MHz MIPS processor and a high-powered DSP designed specifically to process VoIP. Palladia 400 supports a variety of voice codecs such as G.711 (PCM), G.729a/b, G.726.32 and G.723.1. The chip includes support for Caller Identification (Caller ID) — including Japan Caller Identification Protocol (JCLIP), Call Forwarding and Call Waiting. The chip also supports Generic Voice Activity Detection (VAD) and Comfort Noise Generation (CNG) and includes a Message Waiting Indicator, Tele-Conferencing, Call Hold and Pulse Dialing. Palladia 400 also integrates an IPSec engine with support for Data Encryption Standard (DES), Triple Data Encryption Standard (3DES) and Advanced Encryption Standard (AES), as well as Secure Hash and Message Digest Algorithms in hardware.
Applications include home gateways, Integrated Access Devices (IADs), small office-home office (SOHO) voice routers, IP PBXs and other access products with ADSL2+/2++, VoIP, advanced security features and WiFi networking capabilities. Sampling is underway.
Centillium also unveiled the first member of a new family of chips for the VoIP Customer Premises Equipment (CPE) market. The Atlanta 100 chip supports up to eight voice channels for toll-quality telephone voice, fax calls and routing functionality over any broadband access network (ADSL, cable, WiMAX, etc.). The device integrates a RISC processor that performs network management, data routing and other functions. The device also includes a built-in packet accelerator that pushes system performance to wire-speed while supporting multiple VoIP channels in parallel. Atlanta 100 supports a variety of voice codecs, such as G.711 (PCM), G.729a/b, G.726.32 and G.723.1. The chip includes support for Caller Identification (Caller ID) including Japan Caller Identification Protocol (JCLIP), Call Forwarding and Call Waiting. It also supports Generic Voice Activity Detection (VAD) and Comfort Noise Generation (CNG) and includes a Message Waiting Indicator, Tele-Conferencing, Call Hold and Pulse Dialing. http://www.centillium.com
