Integrating a Voice Application on the TDM Infrastructure

Abstract
This paper describes the main challenges when integrating a Linux* user space voice application with the TDM infrastructure of the Intel® EP80579 Integrated Processor with Intel® QuickAssist Technology, examining decisions that are needed when adding features. As an example, the choices made when integrating Asterisk® with this integrated processor are detailed.
The authors present a brief overview of the processor’s TDM Infrastructure interface for Linux user space voice applications. They describe the different options available for adding FXS, FXO and E1/T1 features, along with the choices made during Asterisk® integration. The authors show how an open source DSP software library can be used to add an additional feature to the voice application. The authors conclude with a summary of recommendations on the design decisions for integrating voice applications with a particular architecture.
