Dialogic FAQs


Yes we do purchase Dialogic cards.  Visit our page here to let us know what you have for sell, or just give us a call at 1.800.462.1510.
Some of the analog Dialogic cards such as the D120JCTLSW or D120JCTLSEW have RJ14 jacks instead of RJ11 jacks.  These RJ14 jacks support 2 lines.  So Port 1 supports line 1 and line 2.  To utilize these ports we sell a special cable that connects to a breakout box or can be connected to a punch down block.  We also sell line/combiner splitters to split the lines into 2 separate RJ11 cables.
There are many companies that have created applications for use with Dialogic cards, there are also "toolkits" available that can be used to create your own application.
No, we do not repair Dialogic cards. If we have a defective card, we send it back to Dialogic for repair if it is still in warranty. If you have a defective card that wasn't purchased from Ram PC, contact Dialogic directly for repair options.
Only Dialogic cards that are supported in System Release 6, Service Update 171 or later are supported in operating systems newer than Windows XP and Server 2003.
Most of the Dialogic cards are TAPI compliant though some of the oldest cards such as the D/21D, D/41D and Dialog/4 were not fully TAPI compliant. As of System Release 6 Dialogic is no longer supporting TAPI.
PCIe Power Budgeting Jumper The Power Budgeting Jumper P3 is only found on the PCI-Express cards, and not all them have this jumper but most do. It is a 3-pin jumper to set how the board responds to the system power budgeting function. PCI Express Dialogic JCT Media Boards, Dialogic DMV Media Boards and Dialogic DNI Network Interface Boards are x1 form factor PCI Express boards that require 25W of power. PCI Express slots are are defined as x1, x4, x8, x16 and refer to maximum transfer speed the slot can provide. Each of these slots provides a certain maximum amount of power by default, e.g. an x1 PCIExpress slot provides a maximum of 10W of power by default. The JCT, DMV or DNI PCI Express board must be installed in a slot that can be allocated 25W. If Power Budgeting is not implemented by the computer system, the PCI Express board must be plugged into a x4 or higher slot with the power budgeting jumper in position 1-2 (i.e. power budgeting ignored). This is allowed according to 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 computer system, the PCI Express board can be plugged into a x1 slot but the power budgeting jumper on that board must be in position pins 2-3 (i.e. power budgeting adhered to). According to 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 computer system is not a compliance requirement per the PCI Express Card Electromechanical Specification Revision 1.0a or higher. Therefore, some computers and servers may not support this feature. The power budgeting jumper on the board is designed to ensure proper configuration of the product.
PCI Express (abbreviated as PCI-E or PCIe) is an expansion card interface which was designed to replace PCI, PCI-X and AGP. PCI Express is not backward compatible with any of the previous PCI cards. Only Dialogic cards designed to work with PCIe will work in PCIe slots. System Release 6 SR171 or later is required for the PCIe cards. You can shop for PCI Express cards here.
This applies to any of the cards that have a "W" added on to the end of their model such as D240JCT-T1W, D120JCT-LSW, D41JCT-LSW, D4PCIUFW, or DMV1200BTEPW. The "W" signifies that the card is RoHS compliant. RoHS is the Restriction of Hazardous Substances Directive. It restricts the use of several different materials, such as lead, in the manufacture of various types of electronic and electrical equipment. The cards with "W" in the model name meet the RoHS requirements. The "W" doesn't alter the compatibility or functionality of the card. You can interchange "W" and non "W" cards and your software will still function properly.
The original Dialogic PCI cards such as the D4PCI or D240PCIT1 were 5 volt 32 bit PCI cards. As PCI-X slots came into use most of the PCI cards became available as Universal or "U" versions. The universal designation means that the card is compatible with either 5 volt 32-bit (common to desktop PCs) or 3.3 volt PCI slots including the 64-bit PCI-X slots found in some servers. These cards are NOT compatible with PCI-Express slots. The edge connector on the universal cards is designed so that it will fit into either the 3.3 or 5 volt slot.

ISA slots are the oldest of these 3 slots types and are no longer available from major PC manufacturers. In fact, if you purchased a computer after 1999, it probably doesn't have ISA slots. Computers are still available today with Industrial motherboards that have ISA slots, we sell these ISA slot systems, for more information, click here. PCI is newer than ISA slots, and are still available on computers from the major PC makers, though they are disappearing. We also sell computers with multiple PCI slots, for more information on the these systems click here. PCI cards will only work in PCI slots and ISA cards only work in ISA slots. Click here for a picture showing the difference between ISA and PCI slots. You can generally save money by purchasing the older ISA cards, and if they are compatible with your software you normally aren't giving up any quality or functionality. As of System Release 6, Dialogic has dropped support for all ISA cards. Starting with Windows Vista there Dialogic ISA cards are not supported. PCIe or PCI Express (not to be confused with PCI-X) is the latest PC bus architecture. PCIe is the replacement for both PCI and AGP slots. PCIe is not backwards compatible, PCI cards will not work in the PCIe slots and PCIe cards will not work in PCI slots. Click here for a picture showing the different PCI-e slot types.
If you are using Windows 2000 loading a driver in Device Manager isn't necessary. When the Add New Hardware Wizard comes up, just click cancel. Next, open the Windows Device Manager; the Dialogic card will be listed something like "PCI Bridge Device". Right click on this device and click "Disable". This won't affect the functioning of the card because the functionality of the card comes from the Dialogic System Release, but it will stop the Add New Hardware Wizard from coming up at each re-boot. In Windows XP, Vista and Windows 7 you do have toload an inf file in the Windows Device Manager or the card won't be detected by the Dialogic Configuration Manager. If you run into this issue, you can follow the steps outlined here.
For detailed instructions on installing the Dialogic card and drivers, click here.
If you are purchasing the card to be used in an existing system, the version of the drivers (System Release) you already have should work fine. If you are upgrading operating systems and software you should contact your software vendor to find out which version of the Dialogic System Release you should be using. If purchasing for a new installation, normally your software provider will furnish the System Release that works best with their software. If you need the Dialogic System Release and are purchasing a card, let us know when you order the card and we'll include a driver CD with your order. Contact us for more information.
