DIVA® V-BRI ISDN BOARDS
 The Dialogic® Diva® V-BRI board enables voice, speech, and
conferencing applications. Based on the latest PCI standards, the
Dialogic Diva V-BRI board provides connectivity to the telephony
network via one ISDN Basic Rate (BRI) interface. Powerful digital
signal processors (DSPs) — one dedicated to each communication
channel — ensure real-time voice processing that reduces system
latency and improves overall system performance.
An open and well documented application programming interface
(API), combined with support for a broad range of operating systems, facilitates development of leading-edge voice-based
business applications. The Dialogic Diva V-BRI board is also ideal for taking advantage of the latest advances in speech
recognition technologies and the ubiquity of mobile phones to create exciting new speech solutions.
