Figure 67. Example of Running Log - TDM Capture
While the TDM Capture is running, the fill level of the log is displayed. The log is a circular buffer,
so when it reaches capacity, new data overwrites the old. Once the log reaches capacity, the fill
level does not change.
The log can be transferred to a PC clicking on Download. Doing this brings up a File Download
dialog box as shown in Figure 68. Select Save to save the file to the PC. After saving, you can play
the file using Windows Media Player or view it with a variety of audio file viewers (ex. CoolEdit
Pro, Adobe Audition).

Important points to remember about TDM Capture are:
• It is recommended to stop the trace first so the log file gets its header information written
before downloading.
• TDM capture occurs regardless of channel call state.
• Capture times
– Rx only = ~ 48 minutes (data into DMG2000)
– Rx & Tx = ~ 24 minutes
• Downloading does not require any special software, but viewing requires an audio viewer such
as CoolEdit Pro or Adobe Audition (not freeware).
