• After selecting protocol filters, be sure to click Apply Filters.
•
Size of the log is determined at startup. DMG1000 ~1.1 Mbytes, DMG2000 ~24 Mbytes.
• Downloading the Network Capture clears the log and starts another.
• Stopping the log and restarting it does not clear the log, new data is just appended.
9.4.4 TDM Capture
The TDM Capture creates an in-memory log of voice traffic on the DMG2000's T1 or E1 line. The
capture is controlled from the DMG2000's Web interface, as shown in Figure 66. You can log voice
traffic from a single channel in either the Rx direction, or the Rx and Tx direction, where Rx is
defined as entering the DMG2000 and Tx as leaving the DMG2000. The TDM Capture is not
supported by the DMG1000.

9.4.4.1 TDM Capture Details
Figure 66 shows the default values (i.e. immediately after power-up) for the TDM Capture. You
can select any one channel for logging. The range of channels is dependent on the TDM
configuration (T1 or E1) and the number of hardware spans. Table 18 shows the mapping from a
protocol and span to the TDM Capture channel numbers.
To use the TDM Capture, enter the Channel Number to capture, select either RX or RX & TX, then
click
Start Capturing . Logging begins and the display changes to show the state of the log. An
example of a running log is shown in Figure 67.
