1. Product Description
The Dialogic® D/480JCT-2T1-EW combined media board provides up to 48 channels of voice and media resources and two T1 telephony interfaces in
asingle full-length PCI Express slot.
Additional Information
Additional information about the Dialogic® D/480JCT-2T1-EW board 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 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.
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/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)
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 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.
Setting the CT Bus Termination
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.
Setting Remote Loopback Mode
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.
4. Choosing a Slot
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).
