Trace Options for HiPath 3000 
 
Special user rights are required for activating the Trace setting in the Maintenance menu, that are exclusively reserved by the user group Development.  

12.4.6.1  

Tracing ISDN activities 
This feature allows the user to trace ISDN telephones (subscriber ports) and ISDN trunks (trunk ports) in real time. ISDN activities are routed to HiPath 3000/5000 Manager E and saved in a trace file. Only the ISDN sequences are displayed on the monitor, not the content of the ISDN messages.
The call occurs via HiPath 3000/5000 Manager E: Maintenance, "Call Monitoring" tab. The Start button starts Call Monitoring, whereupon the data of all available ports in the system is read out.
If the trace session is over, you can start the ISDN Message Decoder (ISDN Tracer) and use it to convert the trace file into a readable format (English only). You can also read out the trace data using remote service.
The ISDN Message Decoder is a 32-bit application which converts ISDN layer-3 messages and information elements into a readable format. Since you cannot find out from the trace file whether it deals with an information element from a Euro ISDN or a QSig configuration, you have to select the protocol. You may select the following settings from the main menu:
 •   Raw (default setting)
 •   Euro ISDN
 •   QSig V1
 •   CorNet NQ
With the "Raw" setting, the Hex values are only decoded, not interpreted. With the other two settings, the Hex values are decoded and interpreted for each feature (CC, AOC, etc.).

12.4.6.2  

Tracing call-specific activities 
You can trace all activities that were initiated by a call for telephones, trunks, etc. These include consultation calls, conference calls, and hunt groups, for example.
