Troubleshooting mixed CTbus board systems
If your system uses H.100 Intel Dialogic boards in native CTbus signaling mode, and you
experience problems with board detection or operation, you may need to change the order of
your boards in the PC chassis.
Determine your board type. A board with an H.100 connector can be either an H.100
board or an SCbus board. To determine which type it is, check to see if there is a
dedicated CTbus ASIC chip (-OKI ML53812-x) located within 2 inches of the H.100
connector.
If there is one, it is an H.100 board. If there is no such chip, it is an SCbus board. For
more assistance in identifying the type of board you have, contact your technical support
representative.
Insert your boards in the correct order. Perform this step only if one or more boards
in your system are H.100 boards. If no H.100 boards are in your system, the board order
does not matter.
The appropriate order for the boards in your PCI slots is as follows:
SCbus boards with SCbus connectors (26-pin) must be placed closest to the ISA
slots in the chassis. (If your chassis has no ISA slots, place the boards farthest to the
right, when viewed from the face plates of the boards.)
H.100 boards with H.100 connectors (68-pin) must be next.
SCbus boards with H.100 connectors (68-pin) must be next.
PCI boards not recognized at Server startup
Windows 2000 systems detect but do not recognize Intel Dialogic PCI boards. As a result, when
you restart a Server in which you have installed Intel Dialogic PCI boards, the Windows Found
New Hardware wizard starts for each new board detected. The wizard prompts you to install
drivers for the unknown PCI device.
Important:
Normally, you should NEVER use the Windows Found New Hardware wizard to
install drivers for Intel Dialogic boards. The only time you should use the Found New Hardware
wizard is as described below to resolve this problem with unrecognized PCI boards.
To prevent the Windows Found New Hardware wizard from starting when new
PCI boards are detected
1. Follow the instructions in Chapter 7 to install Intel Dialogic SR 5.1.1, Intel Dialogic
SR 5.1.1 FP1 SU, and the TeleVantage SR 5.1.1 Driver Updates.
2. Verify that the files
dlgcdm3_nt4.inf and dlgcsram_nt4.inf are located in the \DRVR
directory in the Intel Dialogic system directory. The default location is:
C:\Program Files\Dialogic\DRVR\
