TI is providing wireless infrastructure OEMs the industry's most comprehensive, field-tested software to enable the transmission of packet based wireless and converged networks
With the availability of its productised Telogy Software framework on the TMS320C64x DSP, TI is providing wireless infrastructure OEMs the industry's most comprehensive, field-tested software to enable the transmission of packet based wireless and converged networks. With this approach, OEMs can benefit from reduced development time, yet continue to differentiate their offerings by adding their own intellectual property, and that of their development partners, into their solutions.

Customers will have access to the Telogy Software framework, while still controlling the functions and feature sets on the DSP in order to choose from a variety of Telogy Software functional components or add external software components.
'The wireless infrastructure market is extremely important to TI and from a voice perspective, it is entering a stage of dramatically increasing features and complexity', said Brian Glinsman, Director of Infrastructure Solutions in TI's Broadband Communications Group.
'By making our field-tested Telogy Software framework available on a platform optimised for wireless infrastructure applications, we're providing a rapid and powerful way for wireless OEMs to incorporate standards-based voice software into their solutions, while still retaining the ability to differentiate their products'.
The complete Telogy Software framework for wireless infrastructure applications includes the following product features: voice over IP (VoIP) software, including features such as tone detection, tone generation, adaptive playout, packet encapsulation, quality measurements, multi-instance, multi function operations and diagnostics; line or acoustic echo cancellation; a complete library of voice codecs, including G.726, G.729 a/b/e/g, G.728 and G.723.1.a; and a library of wireless codecs, including SMV, EVRC, AMR, WB-AMR and QCELP.
TI's planned roadmap for the Telogy Software framework will also have product features with requirements to meet the needs of 3G wireless, UMTS and CDMA2000 systems, such as: the Telinnovation echo canceller on the C64x device; voice quality enhancement (VQE); tandem free operation (TFO); transcode free operation (TrFO); PSTN/ISDN interworking; and Iu user plane (IuUP) interface.
