3.1 Introduction

This chapter summarizes Fusion AG TRAU functions, which are organized by task. The AG TRAU service provides functions for:

• Loading and unloading AG TRAU programs

• Attaching and detaching AG TRAU channels

• Enabling and disabling AG TRAU channels

• Monitoring channels on AG TRAU Programs

• Processing AG TRAU events

• Sending commands to AG TRAU programs

• Receiving and sending Fusion host-based information

3.2 Loading and Unloading AG TRAU Programs

The following functions load and unload AG TRAU programs on NMS board DSPs:

Function	S/A*	Description
trauLoad	A	Loads an AG TRAU program to an NMS board DSP.
trauUnload	A	Stops AG TRAU program and frees the associated DSP.

*Synchronous or Asynchronous

3.3 Attaching and Detaching AG TRAU Channels

The following functions attach and detach AG TRAU channels to and from CT Access context handles:

Function	S/A*	Description
trauAttach	S	Associates an AG TRAU channel with a CTA context handle (ctahd).
trauDetach	A	Disassociates an AG TRAU channel from a CTA context handle (ctahd) and returns the channel to offline state.

*Synchronous or Asynchronous

3.4 Enabling and Disabling AG TRAU Channels

The following functions enable and disable specific AG TRAU channels:

Function	S/A*	Description
trauEnable	A	Initiates AG TRAU processing on a specific AG TRAU channel.
trauDisable	A	Stops AG TRAU processing on a specific AG TRAU channel.

*Synchronous or Asynchronous

3.5 Monitoring Channels on AG TRAU Programs

trauShowDSPInfo retrieves the location and status of channels running on a specific AG TRAU program. trauShowDSPInfo executes synchronously.

3.6 Processing AG TRAU Events

trauReleaseBuffer frees buffers sent in the event.buffer field so that the application can reuse the buffers. trauReleaseBuffer executes synchronously.

3.7 Changing Program Configuration and Status

trauSendMsg conveys specific routines, or sets optional parameters for AG TRAU channels. trauSendMsg executes asynchronously.

3.8 Receiving and Sending Fusion Host-Based Data

trauRegisterCallback registers Fusion host-based application routines for processing voice data that is read form and written to AG TRAU channels.
