Intel Dialogic System Information Output
When troubleshooting Intel Dialogic problems, use the Intel Dialogic System Information
Output file, which is automatically created in the
\Program Files\TeleVantage Server\Logs
directory each time the TeleVantage Server starts. The file, named tvsysinfoxx.htm , lists the
Intel Dialogic boards installed on the TeleVantage Server, as well as the firmware file and other
board configuration parameters. The latest
tvsysinfoxx.htm file is automatically included with
the other Server logs in the problem report package created by the TeleVantage Problem Report
Wizard.
Intel Dialogic drivers do not start
If you are unable to start the Intel Dialogic drivers after they are installed, do the following:
Q Verify that no other device is using the IRQ assigned to the Intel Dialogic drivers. To do
so, click
Start > Programs > Accessories > System Tools > System Information . In
the System Information dialog box, double-click Hardware Resources , and then
double-click IRQs .
Be sure to access the network with the Intel Dialogic drivers running to ensure the IRQ
is not conflicting with the network card. IRQ conflicts can also cause the system to crash.
If there is a conflict, enter a different free IRQ number for the affected boards.
Q If you experience intermittent problems with boards not starting, and your configuration
includes both PCI and ISA boards, in BIOS reserve for ISA devices the IRQ that is
assigned to Intel Dialogic. This prevents the PCI boards from intermittently using the
same IRQ.
Q Make sure that the network card on a DM/IPx board and the third-party network card are
both connected to the Ethernet hub, and that the IP address of the DM/IPx network card
is not in use by another PC.
Q Verify that DCM recognizes all of your boards, each at the correct ID.
Q If you have a T1 trunk board, in the DCM main dialog box, double-click it and then click
the Interface tab. Verify that the
ISDNProtocol setting reflects the switch protocol used
by your carrier. For a Robbed Bit T1 line, ISDNProtocol should be set to None .
Q If you have a combination of Internet telephony boards (DM/IPx) and T1 trunk boards,
verify that the
Primary Master FRU (User Defined) setting in DCM specifies T1 trunk
board. For instructions, see “Setting digital trunk boards to use the clocking signal sent
by the telephone company” on page 7-17.
