6.Power Budgeting Jumper P3:
3-pin jumper to set how the board responds to the system power budgeting function.

ignores power budgeting values set by system.
Factory default is P3 jumper in pins 2-3.
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.
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
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
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.
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.
