Installing Brooktrout PCI Analog Fax Cards
in the Platform
All PCI fax cards should share IRQ 10 if the platform’s BIOS allows it
. Since Brooktrout PCI
analog fax cards are designed for the PCI expansion bus, the interrupts and memory (I/O)
addresses used by the cards are assigned by the BIOS of the platform, not by configuring
jumpers or switches. For example, a BIOS may allow you to assign IRQ 10 to the expansion
slots you intend to use for the fax cards. Another BIOS may automatically assign IRQ 10 to
the PCI expansion slot based on its location (slot number) in the platform. Refer to the
platform documentation to determine how to configure the platform to assign IRQ 10 to
expansion slots used by PCI fax cards.
In addition, the RightFax BoardServer assigns channel numbers to the PCI fax cards based on
the memory address range assigned to the fax card by the BIOS. The fax card with the lowest
memory address range in the platform is assigned channel 0, and then additional fax channels
in ascending order. For example, a TR114+P2L with the lowest memory address range among
fax cards installed in the platform will be assigned fax channels 0 and 1. A second
TR114+P2L with the next highest memory address range will be assigned fax channels 2 and
3, and so on for all TR114+P2L cards installed in the platform.
If the platform BIOS allows you to assign a memory address range to the PCI expansion slot,
be sure to assign the lowest memory address range to the PCI expansion slot that will contain
the fax card you want to be assigned channel 0. Further, be sure to assign memory address
ranges to additional PCI expansion slots that will contain fax cards in ascending order.
Another BIOS may assign memory address ranges to the PCI expansion slot based on its
location (slot number) in the platform. Refer to the platform documentation for information
about the memory address assignment scheme used by the platform.
Once you have determined a scheme that will assign IRQ 10 to all PCI fax cards, and the
lowest memory address range for the PCI fax card you want to be assigned channel 0 and for
each additional card in ascending order, you can install fax cards into the platform.
IMPORTANT
Brooktrout PCI analog fax cards are
not
approved for use in a platform
containing Brooktrout ISA fax cards. If Brooktrout ISA fax cards are
currently installed in the platform, they must be removed prior to installing
the Brooktrout PCI analog fax cards. Brooktrout PCI analog fax cards are
approved for use with all Dialogic linecards supported by OneBox.
