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.
