Dialogic Diva PRI/E1-30 Media Board streamlines network administration without sacrificing performance. It provides a simple,flexible, and cost-effective solution that allows one server to manage the fax, messaging, and remote access needs of an organization.
The Diva PRI/E1-30 is a board that supports one ISDN Primary Rate Interface (PRI) or E1 interface. It is available in a PCI and a PCI Express version.
The Diva PRI/E1-30 enables one server to support up to thirty concurrent communications with a mix of ISDN devices, V.90 modems, GSM mobile phones, and fax machines, making it an excellent choice for medium to large businesses. Because it is based on open-systems architecture, most industry-leading fax, unified messaging, computer telephony integration, and Voice over IP (VoIP) applications integrate easily when the Diva PRI/E1-30 is used.
Features and Benefits
Supports standardized software interfaces : Has the flexibility to work with many different software packages
Multiple Diva PRI/E1-30 boards can be mixed in one system
with other Dialogic  Diva boards : Provides easy upgrade and scalability
Onboard 32-bit RISC CPU, 64 MB RAM and one Digital Signal Processor (DSP) per channel (24 for T1 and 31 for E1): Removes performance bottlenecks by performing important real-time tasks that would excessively burden the host server on DSP
Group 3 fax, voice mail, and email including DTMS, ECM, RMR, MMR, MH, and 33.6 kbps fax :
Suitable for fax and unified messaging applications
Modem up to V.90, V.42bis compression and V.42 error-correction :Ensures fast and reliable transmission for modems and fax
CAPI, TAPI, and Dialogic Diva Software Development Kit -Version 4.5 including high level functions : Excellent for Interactive Voice Response (IVR) and contact center application
Implements supplementary services : Ensures that applications are compatible with major PBXs
Echo cancellation (G.168) and voice compression in the DSP : Provides the high performance and high voice quality required for VoIP environments
Conforms to plug and play standards : Easy installation and GUI-based configuration
All multinational ISDN protocols : Ready for worldwide use
