1. Product Description
The Dialogic
®
D/41JCT-LS-EW and VFX/41JCT-LS-
EW boards are combined media analog boards with

The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards
include the following components:
J1-J4 jacks: Four RJ-11 jacks to connect to PBX or
telephone network (Central Office) lines.
SW30: Rotary switch used when setting board ID.
SW4: Slide switch used to set hook state at
startup.
CT Bus connector: H.100 telephony bus
connector.
JP2 jumper: CT Bus termination jumper.
JP1 jumper: Not used.
PCI Express connector: Host bus connector.
Compatible with x1 or larger PCI Express Link
connectors.
Additional Information
Additional information about the D/41JCT-LS-EW
and VFX/41JCT-LS-EW boards is available from a
number of sources.
The product data sheet, available at
http://
www.dialogic.com/products/list.asp
, provides a
functional description as well as information about
applications and configurations, features, and
technical specifications.
Refer to the Release Guide and the online Release
Update for your Dialogic
®
System Software release
to verify that the D/41JCT-LS-EW and VFX/41JCT-
LS-EW are supported in the release, and for
information on any new features or issues that may
relate to it.
The Regulatory Notices document that is packed
with each D/41JCT-LS-EW and VFX/41JCT-LS-EW
board contains safety warnings and national
requirements for proper operation of
telecommunications equipment.
2. Before You Begin
Protecting the Board from Damage
CAUTION: All computer boards are sensitive to
electrostatic discharge (“ESD”). Handle all static-
sensitive boards and components at a static-safe
work area, and observe anti-static precautions at
all times.
If you are not familiar with ESD safety precautions,
visit
http://dialogic.com/support/hwinstall
to learn more.
Unpacking the Board
Unpack the board according to the following steps:
1. Prepare a static-safeguarded work area.
2. Carefully remove the board from the shipping
carton and anti-static packaging. Handle the
board by the edges and avoid touching the
board’s components.
3. Lay the board on the static-dissipative work
surface.
Note: Place boards in static-shielding bags when
carrying boards from station to station.
CAUTION: Do not remove the board from the
anti-static packaging until you are ready to install
it. Observe proper anti-static precautions at all
times.
3. Configuring the Board
The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards
use Plug and Play technology to simplify
installation. No user configuration is required for
IRQ or memory address.
The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards
have the following manually configurable options:
■
Board ID
■
Initial hook state
■
CT Bus termination
Setting the Board ID
When the system is started, each Dialogic
®
telecom board is assigned a board instance ID
number that programs can use to identify
individual boards in a multi-board system. The
setting of SW30 controls the generation of the
instance numbers.
Windows Systems: In a Windows system, leaving
SW30 set to the 0 position (the factory default
setting) on all Dialogic
®
telecom boards causes
the system software to assign instance numbers
geographically, based on the bus and slot
numbers. Note that when using this method,
there is no way to know what the instance
numbers will be until the system is started and
configured, and the instance number for any
given board is likely to change when there is any
change in the number or arrangement of boards
in the system.
As an alternative, you may set SW30 on each
board to a different position (0-9 or A-F) to
explicitly assign specific ID numbers to the
boards. Note that each board must be set to a
different ID number.
In either case, you can read the ID numbers
assigned to the boards in the Dialogic
®
Configuration Manager (DCM) after you start the
system and invoke that tool.
Linux Systems: In a Linux system, you must
explicitly specify the board ID numbers by
setting SW30 on each board to a different
position (0-9 or A-F). Refer to the Configuration
Guide for Springware architecture products in
your Dialogic
®
System Software documentation
for further information about the board ID
numbers.
Setting the Initial Hook State
The position of slide switch SW4 determines how
the board responds to an incoming call when the
chassis power is on but the board is not initialized.
Set the SW4 slide switch as follows:
■
SW4 = off (default): Callers hear ringing (on-
hook).
■
SW4 = on: Callers hear a busy signal (off-hook).
Note: If the chassis power is off, callers hear
ringing (on-hook) regardless of the setting of SW4.

Setting the CT Bus Termination
The Computer Telephony bus (CT Bus) provides
communication and flexible resource sharing
among the boards connected to the bus. The D/
41JCT-LS-EW and VFX/41JCT-LS-EW boards have a
CT Bus connector that complies with the ECTF
H.100 specification, and as such can be connected
to the CT Bus with a CT Bus cable. To connect the
boards to the CT Bus, set the CT Bus jumpers
according to instructions in this section.
If you do not require media sharing or switching
across the CT Bus, you may use the D/41JCT-LS-
EW or VFX/41JCT-LS-EWby itself with no CT Bus
cable. If you are not using a CT Bus connection,
you do not need to set the CT Bus jumpers and you
can proceed to Section 4, Choosing a Slot.”
Note: If you are operating the board without a CT
Bus connection, you must configure the board to
H.100 bus mode. Otherwise, all attempts to
download to the board will fail because the CT Bus
clock is absent.
The following instructions apply only to the boards
at each end of the CT Bus cable. Boards that are in
the middle of the CT Bus cable should not be
terminated.
Note: If these boards are operating in SCbus
mode, CT Bus (H.100) termination is not required.
JP1 jumper is reserved and unused. Do not install
a jumper link across the pins of JP1.
JP2 is a 2-pin jumper that is used to terminate the
CT Bus, ensuring that proper electrical
characteristics exist on the CT Bus. By factory
default, this jumper is not terminated on the board.
To use the CT Bus:
■
Install a jumper link on the JP2 jumper of a
board to terminate the CT Bus at that board.
■
Only terminate the first and last boards (the
boards located at each end) on the CT Bus cable.
■
Do not install a jumper link across the pins of
JP2 on boards located between the end boards
on the CT Bus cable (the jumper link must be
disconnected on the JP2 jumper to disable
termination).
The JP2 jumper terminates the following H.100
signals: CT_FRAME_(A&B) and CT_C8_(A&B).
4. Choosing a Slot
The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards
implement a PCI Express x1 lane configuration,
allowing them to be used in any full-length PCI
Express slot that fully meets PCI Express Card
Electromechanical Specification Revision 1.0a or
higher.
If the D/41JCT-LS-EW or VFX/41JCT-LS-EW is the
only Dialogic
®
telecom board in the system, you
may choose any slot for the installation.
