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://www.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 static-shielding bag. 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 Dialogic

®

 D/120JCT-LS-EW board uses Plug 

and Play technology to simplify installation. No user 

configuration is required for IRQ or memory 

address.

The Dialogic

®

 D/120JCT-LS-EW board has the 

following manually configurable options:

Board ID 

Hook-switch state during start-up

Power budgeting (see Choosing a Slot section 

below)

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 SW100 controls the generation of the 

instance numbers.

Windows Systems: 

In a Windows system, leaving 

SW100 set to the 0 position (the factory default 

setting) on all Dialogic

®

 telecom boards causes 

the system release 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 SW100 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 SW100 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 release software 

documentation for further information about the 

board ID numbers.

Setting the Hook-Switch State for Start-
up

Slide switch SW1 determines how the Dialogic

®

 

D/120JCT-LS-EW board responds to an incoming 

call when the PC power is on, but the board is not 

yet initialized.
When the SW1 slider is positioned away from the 

board’s bracket, the Dialogic

®

 D/120JCT-LS-EW 

board responds as on-hook while uninitialized. 

With the SW1 slider positioned closer to the 

bracket, the board responds as off-hook during 

start-up.
The factory default setting for SW1 is on-hook.

4. Choosing a Slot

The Dialogic

®

 D/120JCT-LS-EW board is a full 

length x1 form factor PCI Express board that 

requires 25W of power. The following explanation 

and guidelines are provided to ensure proper 

configuration of the product.
Power Budgeting is a new feature, introduced in 

the PCI Express Specification, that provides a 

mechanism to enable a system to negotiate power 

consumption requirements for add-in devices.
Per PCI Express Card Electromechanical 

Specification Revision 1.0a or higher, a x1 add-in 

card can draw no more than 10W in a x1 slot 

unless the board’s required power is successfully 

negotiated and allocated by the system (power 

budgeting). However, implementation of power 

budgeting by a vendor's system is not a compliance 

requirement per the PCI Express Card 

Electromechanical Specification Revision 1.0a or 

higher. Therefore, some chassis may not support 

this feature. Power Budgeting jumper P3 is 

designed to ensure proper configuration of the 

product.

The Dialogic

®

 D/120JCT-LS-EW board must be 

installed in a slot that can be allocated 25W.
If Power Budgeting is 

not

 implemented by a 

vendor's system, the Dialogic

®

 D/120JCT-LS-EW 

board 

must

 be plugged into a x4 or higher slot 

with the P3 jumper in position 1-2 (power 

budgeting ignored). This is allowed per PCI Express 

Card Electromechanical Specification Revision 1.0a 

or higher because a x4 or greater slot must be able 

to support a minimum of 25W.
If Power Budgeting is implemented by a vendor's 

system, the Dialogic

®

 D/120JCT-LS-EW board 

can

 

be plugged into a x1 slot but the P3 jumper must 

be in position pins 2-3 (power budgeting adhered 

to).

WARNING! Installing the Dialogic

®

 

D/120JCT-LS-EW board in a x1 slot with the 

P3 jumper in position 1-2 will void the 

warranty of the D/120JCT-LS-EW board.

If the Dialogic

®

 D/120JCT-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 (in addition to 

ensuring that the power requirements are met):

Install boards in adjacent slots whenever 

possible.

If the Dialogic

®

 D/120JCT-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 the Dialogic

®

 D/120JCT-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 computer’s cover.
3. Choose an empty PCI Express expansion slot 

and remove the slot’s retaining screw and 

access cover plate.

Physical Layout

1. RJ-14 Jacks, J1-J6: 

Two-line 

analog telephone connectors.

2. SW100: 

Rotary switch used to set 

board ID number.

3. SW1: 

Slide switch to set default 

hook-state of all lines when board 

is powering up. Factory setting 

selects on-hook as the default.

4. CT Bus connector: 

H.100 

telephony bus connector.

5. PCI Express connector: 

Host 

bus connector. Compatible with x1 

and larger PCI Express Link

6. Power Budgeting Jumper P3: 

3-pin jumper to set how the board 

responds to the system power 

budgeting function. 

P3 jumper in pins 2-3: Board 

adheres to power budgeting 

values set by system. 

P3 jumper in pins 1-2: Board 

ignores power budgeting values 

set by system.

Factory default is P3 jumper in 

pins 2-3.
