The Dialogic Diva PRI/T1-24 ("Diva PRI/T1-24") is an exceptionally powerful, active server adapter, which comes as PCI and PCI express variants. Both variants provide identical digital and analog connectivity for up to 24 channels via ISDN Primary Rate (PRI) or T1 Interface.
Diva PRI/T1-24 has 24 on-board DSPs - dedicated to each channel - that support communications with digital devices, V.90 analog modems, fax machines and GSM-compatible mobile phones. This flexibility makes these adapters a perfect platform for remote access, fax, CTI, unified messaging and VoIP gateway applications with full support for voice, fax, GSM and analog calls on up to 24 channels.
Diva PRI/T1-24 adapters represent the highest-capacity server solutions in the Diva® family. Additional Diva PRI/T1-24 adapters can be added any time your need for capacity grows, and can be mixed and matched with other members of the Diva® family.

Features
Benefits
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 realtime 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 on the V-series, UM series, and PRI/E1-30 (applies to 8 channels on PRI/E1/T1-8)
Provides real-time processing of complex operations (such as V.90 data modem, V.34 fax receiver and transmitter, voice compression, or echo cancellation) 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 application 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) on the V-series, UM series, and PRI/E1-30 (applies to 8 channels on PRI/E1/T1-8)
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, including CAPI, TAPI, Dialogic® Diva® APIs, and others
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
Because the Diva PRI/E1/T1-CTI do not have DSPs, they are unable to analyze or modify media such as voice. Their feature sets have been designed to meet the needs of basic voice applications (entry level IVR, call counting, call recording, telephone-voting, small conferencing, etc.).
The Diva V-PRI/E1-30 and Diva V-PRI/T1-24 do not support fax transmission, but offer voice features. Their common feature set has been designed to meet the needs of high-end voice applications (IVR, contact center, large high-quality conferencing, predictive dialing, etc).
The Diva UM-PRI/E1-30 and Diva UM-PRI/T1-24 support fax transmissions on half (50%) of their available channels, offer voice features, and modem connections up to V.90 speeds. Their common feature set has been designed to meet the needs of high-end Unified Messaging applications, which can meet the needs of most of the communication needs of an enterprise.
The Diva PRI/E1-30 supports V.34 fax transmission on all available channels, offer voice features, and modem connections up to V.90 speeds. The Diva PRI/E1-30 provides the most sophisticated communications platform of all the Diva PRI. The Diva PRI/E1/T1-8 (PCI only) combines the functionality of Diva PRI/E1/T1-CTI and Diva PRI/E1-30. On eight channels it offers the feature set of a Diva PRI/E1-30, and on its remaining channels offers the feature set of a PRI/E1/T1-CTI. The Diva PRI/E1/T1-8 has been designed to meet the needs of applications that only need high performance on eight channels.
