D/480JCT-2T1-EW board is available from a 

number of sources.
The product data sheet, available at 

technical specifications.
Refer to the Release Guide and the online Release 

Update for your Dialogic

®

 System Software release 

to verify that the Dialogic

®

 D/480JCT-2T1-EW 

board 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/480JCT-2T1-EW 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.

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.

The Dialogic

®

 D/480JCT-2T1-EW board uses Plug 

and Play technology to simplify installation. No user 

configuration is required for IRQ or memory 

address.

The Dialogic

®

 D/480JCT-2T1-EW board has three 

manually configurable items:

■

Board ID 

■

CT Bus termination

■

Remote loopback mode

■

Power budgeting (see Choosing a Slot section 

below)

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 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 Software documentation 

for further information about the board ID 

numbers.

Note: If you are using this product by itself and 

not connecting it to other telephony boards via a 

CT Bus cable, you do not need to set the CT Bus 

termination jumpers.
Jumpers are used to terminate signals on the CT 

Bus. These settings apply to boards located at 

physical ends of the bus. For CT Bus or SCbus, the 

signals CT_C8_A, CT_C8_B, CT_FRAME_A*, and 

CT_FRAME_B* are terminated using pins 3 and 4 of 

the P700 termination jumpers. For MVIP, C_2 and 

C_4* are terminated using pins 1 and 2 of the P700 

termination jumpers. Bus signals are terminated 

when a jumper clip is installed over the indicated 

pins.
Note: Only the two boards at each end of the CT 

Bus ribbon cable must have their terminations 

enabled. All other boards must not have the 

jumper clips installed.

The Dialogic

®

 D/480JCT-2T1-EW board is shipped 

with SW500 and SW600 set for normal operation, 

with the switch sliders in the position closer to the 

board’s bracket. Setting either switch to the 

opposite position selects the loopback mode for the 

corresponding network interface and overrides any 

board modes set by your application. Loopback 

mode is commonly used to check the network 

connection after the firmware has been 

downloaded to the board.

The Dialogic

®

 D/480JCT-2T1-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/480JCT-2T1-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/480JCT-2T1-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/480JCT-2T1-EW board 

can be plugged into a x1 slot but the P3 jumper 

must be in position pins 2-3 (power budgeting 

adhered to).
