• TDM Capture: The TDM log is a copy of the voice data transferred on the T1/E1 line. It is
available only on the DMG2000.
To view a log you must transfer the log to a PC. When transferred to a PC, each log is formatted
into an industry standard to facilitate viewing and sharing of data. The format for each log is:
• Trace Capture : Uses an ASCII text format (.TXT)
•
Network Capture : Uses an Ethereal format. Ethereal is a freeware program downloadable
from the Internet. It is required only to view Network Captures, not to transfer them from the
Media Gateway to a PC.
• TDM Capture : Uses a Wave file format (.wav). Wave format is a standard Windows

In summarizing the overview of Diagnostic Logging, remember:
• Logging is available on Media Gateway Version 5.0 Software and later.
• The DMG1000 provides two logs: Trace capture and Network capture.
• The DMG2000 provides three logs: Trace capture, Network capture and TDM capture.
• The Media Gateway stores the logs in RAM. Therefore, the logs are not preserved if the unit is

• Special applications are not required to download logs from the Media Gateway to a PC, but
are required to view the logs.
• All control of logging is through the Web interface.
9.4.2 Trace Capture
The Trace Capture enhances the trace mechanism described in Section 9.6, “Trace Mechanism” , on
page 302. Specifically, it allows users to set the trace mask via the Web page in addition to allowing
