 D/120JCT-LSU combined media 

board (“board”) is a 12-port analog telecom board in 
a PCI form factor with universal connectivity 
(support for both 5 V and 3.3 V signaling). The D/
120JCT-LSU is well suited for advanced 
communications applications that require 
multimedia resources. This high-performance, 
scalable product supports voice, fax, and software-
based speech recognition processing in a single 
PCI slot, and provides 12 analog telephone interface 
circuits for direct connection to analog loop start 
lines.

The physical features of the D/120JCT-LSU board 
include the following:

SW100: Rotary switch used to determine board ID

SW1: Slide switch for on/off hook on power up

J1-J6: RJ-14 connectors, two analog telephone 

lines per connector

Additional information about the D/120JCT-LSU 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/120JCT-LSU 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 D/120JCT-LSU board contains safety 
warnings and national requirements for proper 
operation of telecommunications equipment.

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.

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.

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-safe work surface.

Note: Place boards in static-shielding bags when 
carrying boards from station to station.

The D/120JCT-LSU board uses Plug and Play 
technology, including hardware auto-configuration 
for IRQ and memory address. This allows you to use 
the factory default hardware settings for quick 
installation and operation of the board. 

In addition to the automatically configured items, the 
D/120JCT-LSU board has two manually configurable 
options, which are described in the following 
sections:

■

Board ID 

■

Hook-switch state at start-up

When you start Dialogic

 boards, each board is 

assigned an identification for use by the application 
program. The board number is based on the board 
ID that is set through hardware switches on the 
board (rotary switch SW100).

Set the board ID switches to select the board 
sequencing method as follows.

Geographical Sequence (by PCI Bus and Slot 
Number) Board ID 0 (factory default): All 

Dialogic

®

 PCI boards can share the factory 

default setting of board ID 0; in this case, board 
numbers are assigned in ascending order based 
on the PCI bus and slot number. If you add a 
board to the system, it could change the board 
numbering, depending upon the PCI bus and slot 
number where you install it. Also, PCI boards that 
use ID 0 for the geographical numbering 
sequence will be numbered before boards that 
use board IDs 1-9, A-F. The geographical method 
is not available for ISA bus telecom boards.

Programmable Sequence (by Board ID): Board 
IDs 1-9, A-F: In addition to the geographical 

assignment method, the programmable 
assignment method can be used to further identify 
the boards in your system. If you change the 
board ID from the factory default of 0 to any other 
number, the software will use that setting to 
identify the board. This method is also used for all 
ISA bus boards.

CAUTION: When not set to 0 to use the 
geographical sequence method, each PCI board 
must be set to a unique ID number. The ID setting 
must not conflict with the board ID of any other Intel 
ISA or PCI telecom board which has been manually 
assigned. 

Precedence in Mixed Systems: In systems using 

both board numbering methods, or where both 
ISA and PCI boards exist in the same system, PCI 
boards take precedence and will be numbered 
before an ISA bus board that uses a specific 
board ID (1-9, A-F).

Slide switch SW1 determines how the D/120JCT-
LSU board responds to an incoming call when the 
PC power is on, but the board is not yet initialized. 
With SW1 set to the ON position, the D/120JCT-LSU 
board responds as off-hook while unititialized; with 
SW1 set to the OFF position, the board responds as 
on-hook.

CAUTION: These procedures assume familiarity 
with the general terminology associated with 
electronic equipment and with the safety practices 
and regulatory compliance required for using and 
modifying electronic equipment.
These procedures should be performed only by 
qualified technical personnel.

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.

Install each board in the PC chassis using adjacent 
PCI slots according to the following instructions.

1. Turn off all power to the system, and disconnect 

the system's power cords from electrical outlets.

2. Remove the PC cover.

3. Select an empty PCI expansion bus slot, and 

remove the slot's retaining screw and access 
coverplate.
