2.1.2. Determining the Board Types

It is important to know the types of boards you'll be using because some are installed before you install the Intel Dialogic System Software and some are installed after the Intel Dialogic System Software. To determine the type of board you are installing, refer to the Quick Install Card accompanying the board.

The following types of boards are installed before the Intel Dialogic System Software:

• BLT: Board Locator Technology (BLT) boards are uniquely identified by means of a rotary switch on the board. Boards in this category interface to the host through the ISA bus.

  When you run DCM, it automatically detects BLT boards and synchronizes the stored configuration data with the boards it finds in the system.

• PCI: Peripheral Component Interconnect (PCI) boards are uniquely identified by means of their board ID using PCI bus technology. Boards in this category interface to the host through the PCI bus.

  When you run DCM, it automatically detects PCI boards and synchronizes the stored configuration data with the boards it finds in the system.

• cPCI: CompactPCI (cPCI) boards are uniquely identified by means of their board ID using cPCI bus technology. Boards in this category interface to the host through the cPCI bus.

  When you run DCM, it automatically detects cPCI boards and synchronizes the stored configuration data with the boards it finds in the system.

Hardware configurable boards are installed after the Intel Dialogic System Software. Hardware configurable boards are uniquely identified by means of their hardware interrupt level (IRQ), which is set with jumpers, and their base memory address, which is set with DIP switches. Boards in this category interface to the host through the ISA bus.

Note: You must use DCM to determine the hardware interrupt level and base memory address parameters for hardware configurable boards before you install them. If the values for these boards do not correspond to the values in DCM or if another device in the system is attempting to use the same interrupt, port, or address, the Intel Dialogic System will not start successfully.

For this reason, the configuration and installation procedure for these boards is given after the software installation procedure. It is covered in Section 4.3, Configuring and Installing Hardware Configurable Boards.
