1.  Protect Boards 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 Dialogic

®

 VFX/41JCT-LS Media Board 

(“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. 

 

 

 

2.  Set Hardware Switches 

The Dialogic

®

 VFX/41JCT-LS board includes hardware 

auto-configuration for IRQ and memory address. This 
technology lets you use the factory default hardware 
settings for quick installation and operation. However, 
we recommend that you review the following 
information before installing your board and select any 
options as desired. 

A.  Set the Board ID Number 

When you start Dialogic

®

 boards, each board is 

assigned a sequential number for identification and use 
by the system software. This sequential number 
specifies the device and channel name(s) for each 
board. The board number is based on the board ID that 
you set using the SW30 rotary switch on the board. 

Use the

 

SW30 rotary switch to specify board 

sequencing as follows: 

 

 

 

Automatic Assignment: Board ID 0 

Also called geographical method. All Dialogic

®

 PCI 

boards can share the factory default setting of board 
ID 0. In this case, boards are automatically sorted by 
PCI bus and slot number. 
 

Note: 

Adding or removing a board can cause the 

renumbering of boards in the system. Consequently, 
the assignment of device names may change during 
the next system start-up.  

 

 

Manual Assignment: Board IDs 1–9, A-F

 

In addition to the automatic assignment method, you 
can use the manual or discrete assignment method to 
further identify 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.  
 

Note: 

When not set to 0, the board ID must be 

unique. It must not conflict with the board ID of any 
other Dialogic

®

 ISA or PCI board. If you use this 

method, we recommend that you assign sequential 
numbers starting at 1. This method is also used for 
all ISA bus boards. 

Numbering Precedence in Mixed Systems 

In systems using both automatic and manual assignment 
methods, or where both ISA and PCI boards exist, PCI 
boards take precedence and are numbered before an ISA 
board that uses board IDs 1-9 or A-F.  

Note: 

The Dialogic

®

 software can correctly register 

your boards for proper operation; however, due to 
variations among computer chassis, it is not possible for 
the software to determine where each board is 
physically placed. For more information on board ID 
numbering issues, see the 

Dialogic

®

 Installation and 

Configuration Guide

 for your operating system or visit 

the Dialogic Technical Support website at 

http:/www.dialogic.com/support/helpweb/

B.  Set the Hook-Switch State for Start-Up 

(Optional) 

Set the SW4 switch as follows to select how the board 
responds to an incoming call when the computer power 
is on but the board is not initialized. 

Ringing (On-Hook)

SW4
OFF

 

SW4 = Off (default): 

Callers hear ringing (on-hook). 

SW4

ON

Busy (Off-Hook)

 

SW4 = On: 

Callers hear a busy signal (off-hook). 

Note: 

If the computer power is off, callers hear ringing 

(on-hook) regardless of the setting of the SW4 switch. 

 

 

3.  Set CT Bus Jumpers (optional) 

The Computer Telephony bus (CT Bus) provides 
communication and flexible resource sharing among the 
boards connected to the bus. This Dialogic

®

 board has 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. 

You can connect the board to the CT Bus or use it 
without the CT Bus in stand-alone mode. 

„

 

Stand-Alone Mode (CT Bus Jumpers Ignored): 

For applications that do not require media sharing or 
switching across the CT Bus, use the board in stand-
alone mode. No CT Bus cable is required. You can 
skip the rest of this section and proceed to 

Section 4

 

Install the Board

.” 

 
In addition, you may skip the instructions in this 
section when you use the board in SCbus mode 
without a CT Bus master board; that is, using only 
SCbus master/slave boards. 

„

 

CT Bus Mode (CT Bus Jumpers Needed): 

To 

connect the boards to the CT Bus, set the CT Bus 
jumpers according to instructions in this section. 

 

Note:  

If these boards are operating in SCbus mode, CT 

Bus (H.100) termination is not required. 

The following instructions only apply to the boards at 
each end of the CT Bus cable. Only boards at each end 
of the CT Bus cable must be terminated.  

JP1 jumper is reserved and unused. DO NOT install a 
shunt 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 the shunt 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 shunt across the pins of JP2 on 

boards located between the end boards on the CT 
Bus cable (the shunt must be disconnected on the 
JP2 jumper to disable termination). 

The JP2 jumper terminates the H.100 signals listed in 
the following table. 

 

Shunt 

H.100 signal terminated 

JP2, Pins 1 and 2 (used 
on boards at each end of 
CT Bus cable only) 

CT_FRAME_(A&B) 
CT_C8_(A&B) 

 

 

 

4.  Install the Board 

 

 

Warning!

 

To reduce the risk of electric shock: 

 

 

Switch off the power and disconnect all power cords. 

 

 

Do not re-attach power cords or switch on power to 
the computer while the computer cover is removed. 

Install the board in the computer chassis according to 
the following instructions: 

1.

 

Remove the computer cover. 

2.

 

Select an empty PCI bus slot, and remove the slot’s 
retaining screw and access coverplate. 

16-Bit ISA Slots

32-Bit PCI Slots

Retaining Screw

Metal Coverplate for Slot

 

 

Note:

 If you are not installing your board in an ISA 

form-factor PCI slot, remove the slot retainer bracket 
from the end of the board before installation.
