Installing the Dialogic®
Brooktrout® TruFax® BRI
PCI Board
Part Number: 931-107-05
The Dialogic® Brooktrout® TruFax® BRI
(Basic Rate Interface ISDN) PCI boards are half-
sized, single-slot PCI-bus compatible fax processing
boards. They provide the following:
On-board BRI connections
Up to four V.17 fax channels per board
The TruFax® BRI PCI Series boards can be used in
either 3.3V or 5V bus (signaling) slots.
You need a fax application to use a TruFax® BRI
board. Dialogic does not provide the application or a
driver for this board. A driver comes with the
application that you purchase.

Telephone service: BRI interface
Setting the Module Number
Set each board to a unique module number to easily
identify the resources associated with a specific board
in a multi-board system.
Use the SW-1 rotary switch (Figure 1) to set a unique
module number for each Dialogic® Brooktrout®
board. See Figure 5 for the switch location. Select a
number from 2 - F on the rotary switch. Settings 0 and
1 are reserved and cannot be used.
Figure 1. Rotary Switch (SW-1)
Setting Termination Jumpers
for the BRI Line
Before installing your board, set termination for the
BRI line if necessary. See Figure 5 for the location of
the termination switches.
Set jumpers as follows (See Figure 2 for details):
Figure 2. Termination Jumpers
When the jumpers are removed from both
switches for the appropriate port, there is no
termination.
When jumpers are present, the lines are
terminated with 100
ohms (this is how the boards
are shipped)
.
Dialogic does not support any configuration
except the two illustrated in Figure 2.
Installing the Dialogic®
Brooktrout® Board
To install your board:
1.
Turn off your PC and remove the cover.
2.
If the system has a PCI expansion hold-down bar,
remove it.
3.
Locate a free PCI bus slot and remove the slot
cover.
4.
Carefully align the board with the slot and firmly
seat the board into the slot.
5.
Tighten the mounting bracket screw to secure the
board to the chassis.
6.
Replace the cover.
7.
Turn on your computer.
Note:
Dialogic® Brooktrout® boards should not be present in the
computer during the installation of any operating system.
The operating system might misinterpret the board as being
some other device, with unpredictable consequences.
Recognizing PCI Slots
The PCI connectors in the computer chassis usually
appear as white slots. The TruFax® BRI board has a
PCI board edge connector. It can be inserted into any
of the PCI slots shown in Figure 3.
Figure 3. PCI Slots
Connecting the Phone Service
The appropriate telephone service and hookups must
be installed at your site in order to connect to
telephone service. The following table shows the
channel/port relationship:
Use the cable supplied with the board. Use these
instructions to connect your board to BRI service:
1.
Plug one end of the cable into the telephone
connector on the board.
Connect to Port A for channels 0 and 1 or to
Port B for channels 2 and 3 (see Figure 5 to
locate ports).

Caution: A small amount of static electricity can destroy
the sensitive components on your board. To prevent
static damage, always connect yourself to ground using
a ground strap before touching a circuit board. Handle
boards only by the edges or metal mounting brackets
and transport boards in an anti-static bag.
Warning: When installing the board, be sure that the
mounting bracket is securely fastened to the chassis and
the chassis is plugged into a grounded three prong plug.
Improper chassis or bracket grounding can result in
harmful or fatal electrical shock as well as component
damage.
