If the D/41JCT-LS-EW or VFX/41JCT-LS-EW will be
connected to other telephony boards via a CT Bus
cable, you should install the boards to minimize
unused connectors on the CT Bus cable:
■Install boards in adjacent slots whenever
possible.
■If the D/41JCT-LS-EW or VFX/41JCT-LS-EW
board will be connected to one or more PCI
boards, use the PCI Express slot(s) closest to the
PCI slots.
5. Installing the Board
WARNING! Unplug the equipment before
performing the procedures described here.
Failure to disconnect the power before you
open the chassis can result in personal injury.
Ensure that the system is disconnected from
its power source and from all
telecommunications links, networks, or
modem lines whenever the chassis cover is
removed. Do not operate the system with the
cover removed.
CAUTION: To avoid possible damage to the board,
remove power from the computer before beginning
installation. Observe proper anti-static precautions
at all times while handling and installing the board.
To install a D/41JCT-LS-EW or VFX/41JCT-LS-EW
board, perform the following steps:
1. Turn off all power to the system and disconnect
the system’s power cords.
2. Remove the compute r ’s cover.
3. Choose an empty PCI Express expansion slot
and remove the slot’s retaining screw and
access cover plate.
Note: If you are not installing the board in
a full-length form-factor PCI Express slot,
remove the slot retainer bracket from the
end of the board before installation.
4. Insert the board’s edge connector into the bus
slot, and apply firm pressure to the top edge of
the board until the board is fully seated in the
edge connector.
5. Reinstall the retaining screw.
6. Repeat steps 1 through 5 for any additional
boards you are installing.
7. If applicable, connect the telephony boards
together with a CT Bus cable of the appropriate
size (not included). If possible, use a cable
assembly that matches the number of boards in
your system. If the cable has more than one
unused connector, install the cable so that all
the unused connectors are at one end of the
cable.
8. Replace the computer ’s cover.
9. Reconnect the computer ’s power cord.

6. Connecting to External Equipment
Each RJ-11 jack on the rear bracket of the
D/41JCT-LS-EW and VFX/41JCT-LS-EW boards
supports a single channel. Use RJ-11 connectors
and telephone cable to connect each channel to an
analog PBX or standard telephone outlet.
Note: Since these boards emulate a standard
telephone, a standard telephone will not function
when directly connected to the board.
Note: Connect the Earth Recall signal to pin 2. Do
not connect Tip or Ring lines to pin 2, or improper
operation of the D/41JCT-LS-EW or VFX/41JCT-LS-
EW will result.
7. After Installing the Board
The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards
require the use of an Dialogic® System Software
version that specifically supports it.1
If this is the first Dialogic® telecom board you have
installed in your system, you will need to install an
appropriate version of the Dialogic® System
Software and configure the software for the specific
board(s) you are using. Refer to the installation
and configuration documentation that accompanies
the release for instructions.
1.Required Dialogic® System Software:
System Release 6.0 PCI for Windows Ser-
vice Update 131 or higher; System Release
6.1 for Linux Service Update 232 or higher.

If you are installing the board in a system that
already has the Dialogic® System Software
installed, you should verify that your installed
software version supports the board. If not, you
will need to obtain and install a Service Update that
does support the D/41JCT-LS-EW and VFX/41JCT-
LS-EW boards before configuring the system for
the newly installed board(s).
Please refer to the Release Update document for
your release version (on the Dialogic Telecom
Support Resources web page) for up-to-date
information about support for PCI Express boards
and any known issues relating to their use.
8. Removing the Board
Removal of the D/41JCT-LS-EW and VFX/41JCT-LS-
EW board is essentially the reverse of the
installation procedure:
1. Observe anti-static precautions.
2. Disconnect the telephony cables.
3. Remove the computer’s power cord.
4. Remove the computer’s cover.
5. Disconnect the CT Bus cable (if applicable).
6. Remove and set aside the board’s retaining
screw.
7. Remove the board and place it in static-
protective packaging.
