Dialogic Diva 4BRI-8 - Voice interface card - PCI - SDLC, HDLC, PPP, MLPPP
- 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
- One powerful DSP dedicated to each communications channel
- Sophisticated hardware design
- Conforms to plug-and-play standards
- Implements most supplementary services, many signaling protocols, as well as all multinational ISDN protocols
- Voice packetization into Real-time Transport Protocol (RTP), adaptive jitter buffer, voice compression (G.726, GSM), and Comfort Noise Generation (CNG) available
- Supports the same programming interfaces as other Dialogic Diva Media Boards
- Up to eight Diva Media Boards of the same or different types can operate concurrently in a single server
The Dialogic Diva BRI (ISDN Basic Rate Interface) Media Boards provide four ISDN BRI ports and can serve as an excellent communication platform, which scales from 2 to 64 channels (phone lines) per single server.
The Diva BRI offer voice, speech, conferencing, VoIP, modem and fax features, and can serve as a base for many communication applications. The boards support most standard applications, and are also suitable for new application development. The Diva BRI can be seamlessly combined with other Dialogic Diva Media Boards. The Diva BRI PCI boards share the same features with their PCI Express (PCIe) versions, so that the migration from PCI Server hardware to PCI Express hardware is easy. Sometimes it will be beneficial to be able to use PCI and PCIe versions in the same server. The Diva BRI support the same set of programming interfaces as other Diva Media Boards: the three Dialogic Diva APIs, CAPI, TAPI, COM port, WAN Miniport, TTY, Asterisk, and SIP/RTP. Because of this consistent interface support, applications written for another Diva Media Board will normally work without modification with Diva BRI.

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
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.
-
One powerful DSP dedicated to each communications channel
Provides real-time processing of complex operations (such as V.90 data modem, V.34 fax receiver and transmitter, voice compression, or echo cancelation) without reducing overall system performance, which lowers implementation costs.
-
Sophisticated hardware design
Operates with low power consumption.
-
Conforms to plug-and-play standards
Permits easy installation and operation.
-
Implements most supplementary services, many signaling protocols, as well as all multinational ISDN protocols
Allows applications compatibility with major PBXs and can make a system based on Dialogic Diva technology ready for worldwide use.
-
Voice packetization into Real-time Transport Protocol (RTP), adaptive jitter buffer, voice compression (G.726, GSM), and Comfort Noise Generation (CNG) available
Permits legacy voice, speech, and conferencing applications to be used with VoIP clients and IP phones.
-
Supports the same programming interfaces as other Dialogic Diva Media Boards
Reduces porting efforts and time to market by making Diva Media Boards compatible with most standard telephony and communications applications.
-
Up to eight Diva Media Boards of the same or different types can operate concurrently in a single server
Easy scalability and flexibility to address an organization's communications needs in changing environments, such as VoIP.
