Dialogic Diva Analog-2 Media Boards
Two-port ISDN Basic Rate Interface Media Boards

Overview:

The Dialogic Diva Analog Media Boards provide two, four, and eight ports and serve as an excellent communication platform, which scales from 2 to 64 channels (phone lines) per single server.

The Diva Analog Media Boards offer voice, speech, conferencing, VoIP, modem and fax features, and can serve as a base for many communication applications.  The boards are supported by many standard applications, and are also suitable for new application development. Diva Analog Media Boards are available in Low Profile, Half Size, or Full Size form factors and are available in both PCI and PCI Express (PCIe) versions. Diva Analog can be seamlessly combined with other Dialogic Diva Media Boards, such as E1/T1, ISDN PRI/BRI, and VoIP.

Because both PCI and PCIe versions share the same feature sets, migration from a PCI Server hardware to PCI Express hardware is easy. PCI and PCIe versions can also be used in the same server.

The Diva Analog Media Boards 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.  Because of consistent interface support, applications written for one Diva Media Board will normally work without modification with Diva Analog Media Boards.

The Diva UM-Analog-2, UM-Analog-4, and UM-Analog-8 Media Boards support fax transmissions on half (50%) of their available channels.  The feature set of the Diva Media Boards in the UM series has been designed to meet the needs of typical Unified Messaging applications.

The Diva Analog-2, Analog-4, and Analog-8 boards support V.34 fax transmissions on all available channels.  The Diva Analog-2, Analog-4 and Analog-8 boards are normally referred to as part of the Universal series.

Features and Benefits:

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 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 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 and many different analog signaling protocols	Allows applications compatibility with major PBXs and can make a system based on Dialogic Diva technology ready for worldwide use
Pulse and tone dialing	Handles enterprise voice, conferencing, fax, and remote access applications via any PBX offering analog trunk interfaces
Voice packetization into Real-time Transport Protocol (RTP), adaptive jitter buffer, voice compression (G.726, GSM), and Comfort Noise Generation (CNG)	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, 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
