4.5. Setting the Encoding Method for DM3 E-1 Applications

The PCM encoding method for DM3 boards is defined using the Media Type (User Defined) parameter in DCM. Initially, the value selected is Default. This causes the system to default to the initial value of m-law which is determined by the Media Type (Resolved) parameter. To change the PCM encoding method to A-law for DM3 boards in E-1 applications, perform the following:

1. On the DCM Main Window (Figure 8, DCM Main Window), double-click Bus-0 under TDM Bus in the DCM tree structure of configured devices. This displays the TDM Bus Configuration property sheet for Bus-0.
2. Set the Media Type (User Defined) parameter to ALaw.
3. Click the Apply and then the OK button to set the parameter and return to the DCM Main Window.

Go to the next relevant configuration activity.
