Installation Guide

1. Product Description

The Dialogic

D/120JCT-LS-EW combined media

board is a 12-port analog telecom board in a PCI

Express form factor. The Dialogic

D/120JCT-LS-

EW supports voice, fax, and software-based speech

recognition processing in a single PCI Express slot,

and provides 12 analog telephone interface circuits

for direct connection to analog loop start lines.

Additional Information

Additional information about the Dialogic

D/120JCT-LS-EW is available from a number of

sources.
The product data sheet, available at

http://www.dialogic.com/products, 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 release software

to verify that the Dialogic

D/120JCT-LS-EW is

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 Dialogic

D/120JCT-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://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.

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.
