Adaptive Digital Announces Software Solution That Turns TI DSPs Into Voice Over Packet Engines

Adaptive Digital Technologies, Inc. announced availability of G.PAK, a scalable and configurable voice-over-packet DSP solution that provides sufficient flexibility to be used in nearly any voice application. G.PAK integrates the DSP building blocks required in voice-over-packet system into a user friendly turnkey solution without the need to learn DSP code System designers can therefore leverage a proven solution, allowing them to focus their efforts on rapid product development. G.PAK runs on the Texas Instruments TMS320C5400 family of Digital Signal Processors.

Adaptive Digital's G.PAK insures short time to market since there is no need to reinvent the wheel. In fact, with G.PAK, there is no need to write a single line of DSP code. G.PAK provides all of the DSP components necessary in a voice-over-packet system and provides an application interface to allow easy integration into a user's application. Adaptive Digital's G.PAK base algorithm set includes G.711 and Adaptive Digital certified "carrier class", patented implementation of an ITU G.168 - 2000 compliant network echo canceller. Custom solutions are built upon this base set by adding Adaptive Digital's field proven algorithms or customer supplied algorithms. The G.PAK software image loads directly on the DSP.

Adaptive Digital's building block algorithms include G.711 PCM, G.726 ADPCM, G.168-2000, Tone Detection and Generation, Tone Relay, Voice Activity Detection / Comfort Noise Generation, Silence Suppression, G.729AB 8 kbps speech coder, G.723.1 6.3/5.3 kbps speech coder, G.728 16, 12.8, or 9.6 kbps vocoder, Caller ID, and Fax Relay.

Adaptive Digital boasts runtime and build time configurability. In order to maximize channel density, G.PAK is configured specifically for the user's application. Each channel is configured at runtime to interface between the appropriate port types. Port types include PCM, Packet, and Circuit Data. The most common channel configuration is PCM on one side of the channel and packet data on the other side of the channel (a PCM to Packet channel.) Other configurations include PCM to PCM, Packet to Packet, and Circuit Data. The result is true universal port operation.
