Diva Boards

Diva (V-xPRI) Multi-Span
E1/T1/PRI Boards

The Diva V-xPRI offer voice, speech, conferencing, VoIP, modem and fax features and can serve as a base for many communication applications. The boards support many standard applications, and are also suitable for new application development.

The Diva V-xPRI are available in Half Size and Full Size PCI Express form factor. The Half Size version has 12 DSPs and comes in versions for 1, 2, and 4 trunks. The Full Size version has 24 DSPs and comes in versions for 4 and 8 trunks.

The Diva V-xPRI can be seamlessly combined with other Diva® Media Boards, such as those supporting Analog, ISDN BRI, and VoIP.

PCI and PCIe versions can be used in the same server providing both can be physically supported by the server.

The Diva V-xPRI support the same set of application interfaces as other Diva Media Boards: the three Dialogic® Diva® APIs as well as CAPI, COM port, WAN Miniport and TTY. Although Diva Media Boards share the same interfaces, the Diva V-xPRI are the only ones that have the flexibility to allow a customer to upgrade the initial “V-series” voice feature set with four additional software licenses at any time:

Modem — Offering modem connections up to V.90 speeds
VoIP — Offering VoIP CODECs (AMR-NB, G.729, RTaudio)
G.723 — Offering the G.723 CODEC
Fax — Offering V.34 fax up to 33.6 kbps speeds

Because of consistent interface support, applications written for another Diva Media Board with comparable functionality will normally work without modification with the Diva V-xPRI Media Boards.

Details

The former license bundles have been replaced by the more flexible and additive licenses. Customers can now order the exact required quantity of channels.
Please note that the Diva V-4PRI PCIe HS (306-396) and the Diva V-8PRI PCIe FS (306-404) media boards may have limitations when running V.34 and higher modem or fax protocols on all available channels. Please contact your Sangoma Sales Office for details.

Key Features and Benefits

Scalable

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

Compatibility

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.

Interoperable and Future Proof

Supports the same programming interfaces as other Diva® Media Boards, including CAPI, Diva® APIs, and others. Permits legacy voice, speech, and conferencing applications to be used with VoIP clients and IP phones.

On-Board DSP

One powerful DSP dedicated to each communications channel on the V-series, UM series, and PRI/E1-30. Depending on the version of the Diva V-xPRI Media Board, 3, 5, 6 or 12 powerful DSPs are available per trunk (E1/T1/J1/ISDN PRI).

Flexible and Reduces Footprint

Up to eight Diva Media Boards of the same or different types can operate concurrently in a single server. Implements most supplementary services, many signaling protocols, as well as all multinational ISDN protocols.

Fax

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.

Transcoding

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

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.
