Diva Boards

Diva Analog Boards

The Diva Analog Media Boards offer voice, speech, conferencing, VoIP, modem and fax features, and can serve as a base for many communication applications. The boards are supported by many standard applications and are also suitable for new application development. Diva Analog Media Boards are available in Low Profile, Half-Size, or Full-Size form factors and are available in both PCI and PCI Express (PCIe) versions. Diva Analog can be seamlessly combined with other Diva® Media Boards, such as E1/T1, ISDN PRI/BRI, and VoIP.

Because both PCI and PCIe versions share the same feature sets, migration from a PCI Server hardware to PCI Express hardware is easy. PCI and PCIe versions can also be used in the same server.

The Diva Analog Media Boards support the same set of application interfaces as other Diva® Media Boards: the three Diva® APIs as well as CAPI, COM port, WAN Miniport and TTY. Because of consistent interface support, applications written for one Diva Media Board will normally work without modification with Diva Analog Media Boards.

The feature set of the Diva Media Boards in the UM series has been designed to meet the needs of typical Unified Messaging applications.

The Diva Analog-4, and Analog-8 boards support V.34 fax transmissions on all available channels. The Diva Analog-4 and Analog-8 boards are normally referred to as part of the Universal series.

Key Features and Benefits


Easy scalability and flexibility to address an organization’s communications needs in changing environments, such as VoIP.


Allows application compatibility with major PBXs and can make a system based Diva® technology ready for worldwide use.

Quick Plug-and-Play Deployment

Reduces porting efforts and time to market by making Diva Media Boards compatible with most standard telephony and communications applications.

Efficient, Easy Design

Operates with low power consumption, has a sophisticated hardware design, and permits easy installation and operation.

Future Proof

Supports the same programming interfaces as other Diva® Media Boards, including Diva® APIs, CAPI, TTY, COM port, and others.

SUP.Services and Protocols

Implements most supplementary services and many different analog signaling protocols.

Flexible PBX Performance

Handles enterprise voice, conferencing, fax, and remote access applications via any PBX offering analog trunk interfaces.


Permits legacy voice, speech, and conferencing applications to be used with VoIP clients and IP phones.


Voice packetization into Real-time Transport Protocol (RTP), adaptive jitter buffer, voice compression (G.726, GSM), and Comfort Noise Generation (CNG).

Keep Host Performance

Can remove performance bottlenecks by offloading key real-time tasks that would ordinarily place an excessive burden on the host server, allowing Quality of Service (for example, voice quality and connection speed) to be more consistent.

Real-Time Processing

Provides real-time processing of complex operations (such as V.90 data modem, V.34 fax receiver and transmitter, voice compression, or 256 ms echo cancellation) without reducing overall system performance, which lowers implementation costs.

Powerful On-Board Performance

Onboard CPU with large RAM and powerful FPGA chip for fast data streaming between the host CPU, the DSPs, the phone line, and the other active components onboard.
