Aculab System Diagnostics
The Aculab System Diagnostics is a command line based tool for monitoring trunk activity on TDM telephony based on Prosody and Prosody X based hardware.
The application provides a convenient way to
- verify that the connected trunks are active
- check the error status of the trunks
We recommend that you place a shortcut to this tool on the desktop.
Running System Diagnostics
The tool may be found at C:\softdial\aculab\bin\sysdiag.exe. On starting the application, you will see the following command line window (Fig. 1):

This window is a simplified view of what you see in the Port Properties tab of the CallLab Card Manager window. (See Testing 1 - Aculab hardware and drivers - 1.5) Check Port Statistics tab)
Layer 1 statistics
In the Layer 1 Statistics section:
- the error flags (NOS, AIS, LOS etc) should all be zero (0x0)
- the USR value should be 0xf1
- the Bipvios/ Faserrs/ Sliperrs fields should not be increasing in value
This indicates that
- the physical connection is good
- the electrical connection is good
- the two endpoints are synchronised and able to exchange bytes of data without error
You may see some values in the Bipvios/ Faserrs/ Sliperrs fields or some errors listed in the LineStat box but these may be left over from a previous error e.g. on start up. To check this go to CallLab / Card Manager / Port statistics and click Reset Port. If these go away and stay away, then all is well.
Layer 2 statistics
In the Layer 2 statistics (L2 State), you should see a line of 1s (either 30 for E1 connections or or 23 for T1). This indicates that
- the protocol chosen is compatible with the remote endpoint
- both ends are in a state where the channels can all be used.
There is an exception to this: in the case of CAS (Channel Associated Signalling) type protocols the indicators will remain at 0 because for CAS protocols the channels are all used individually with no overall control, as if they were 24 individual telephone lines.
