Dialogic® Diva® PRI/E1/T1-8

Diva PRI/E1/T1-8 Board

This is the board to use when only 8 channels need media processing, e.g. for fax, conference or modem. NOTE: Soon to be removed - "End of Life"


Digital T1 or E1 interfaces are often the most economic means of connecting server based fax, voice and data applications to a telephony switch, even when all 24 or 30 available channels are not required for the initial size of the application.

The Dialogic Diva PRI/E1/T1-8 ("Diva PRI/E1/T1-8") has been specifically designed to meet these market requirements. Offering digital network interfaces selectable for full and fractional E1, T1 or ISDN Primary Rate (PRI) standards, Diva PRI/E1/T1-8 allows for proven and reliable connectivity with all kinds of PBX and switch systems.

As such, Diva PRI/E1/T1-8 offers key voice processing functionality required for voice mail, IVR, call center or alarm server applications. Thanks to an additional eight dedicated DSP-based media processing resources, up to eight calls out of the total E1 or T1 span can concurrently handle the most demanding operations such as V.90 data modem, high-speed 33.6 kbps fax or enhanced echo cancellation.

Diva PRI/E1/T1-8 offers a simple and powerful, yet cost-effective entry-level CTI and Fax platform.

Application Notes

Data Sheet

  • Dialogic® Diva® PRI Media Boards
    The Dialogic® Diva® PRI Media Boards are building blocks for enabling speech and Voice over Internet Protocol (VoIP) applications. The Diva PRI Media Boards are based on the latest PCI and PCI Express standards, and provides connectivity to the telephony network via ISDN PRI, E1 or T1 interfaces.

Technology Brief

  • Dialogic® Diva® Software Development Kit
    The Dialogic® Diva® Software Development Kit (Diva SDK) offers a powerful set of Application Programming Interfaces (APIs) that can be used for implementing telephony applications, that is, applications that accept and process phone calls.
  • Dialogic® Diva® Media Boards and an Asterisk IP-PBX

    To connect to the PSTN, Asterisk systems require a network interface board or a media gateway. Because most Dialogic® Diva® Media Boards have powerful Digital Signal Processors (DSPs) onboard and can move processor-intensive, low-level tasks to these DSPs, significant reductions in server CPU load are possible. Such reductions can positively impact overall performance and scalability in systems such as those using Asterisk software.

White Paper

  • Choosing the Right Communication Adapter for Speech-Enabled Systems
    Advanced speech-enabled applications and systems are changing the way in which we interact with all types of businesses. Moving beyond a few showcase situations, speech technologies are being used in many new and exciting applications, such as voice portals, call center self-service, directory assistance, and voice-activated dialing. With speech applications customers can obtain information or direct transactions using the most intutitive interface - speech. When used in conjunction with IVR and self service applications speech recognition technology greatly reduces the cost of staffing a call center operation, while reducing call durations and call handling time and increasing call completion rates.
  • Choosing the Right Communication Adapter for IVR Systems
    Interactive Voice Response (IVR) is probably one of the most widely used technologies today. IVR is one of the most useful and cost-effective technologies around, with applications encompassing movie schedules, bank tranfers, reserving plane tickets, and refilling prescriptions.

  • V.34 Fax - Making Improved Performance and Cost Savings Possible
    This white paper discusses the V.34 fax standard, and how those choosing to adopt 33.6 kbps fax devices and use V.34 fax technology can position themselves for benefits such as increased cost savings.
  • Choosing the Right Media Board for IVR Systems
    This white paper discusses what ISVs and system integrators should consider in a media board for IVR systems, and why they must carefully select the right board for their needs.
