Dialogic Boards

Diva Analog Boards

Sangoma Diva Analog CardThe 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.

Diva Media Board Features

Power Icon
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.

On Premise Icon
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.
Telephony Cards

Sophisticated hardware design.

Plug and Play
Conforms to plug-and-play standards.
Interoperability Icon

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