Dialogic Diva V-xPRI Modem Boards
High Density Modem - E1 / T1 - PCIe

Overview:

The Diva V-xPRI Media Boards are available in 1, 2, 4 and 8 E1/T1 variants, and offer the scope to build high-density modem banks with up to 240 ports in a single server. The wide range of modem protocols make them well suited for a variety of applications ranging from point of sale termination and M2M modem applications, network and protocol test equipment, to monitoring and termination of utility metering devices.

Supported under both Windows and Linux, the V-xPRI Boards enable COM port or TTY port emulation in the operating system, allowing for transparent support of existing modem / COM port applications.

Support for V.22FastConnect, V.22bisFastConnect and V.29FastConnect minimizes training and connect time, to beneficially increase overall data acquisition and transfer rates per channel.

Modem standards supported

• Bell 103, Bell 212A, V.21, V.22, V.22 fast connect, V.22bis, V22bis fast connect, V.29, V.29 fast connect, V.32, V.32bis, V.34, V.90 V.42, V.42bis, MNP4, MNP5, V.110, V.120

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 data integrity and connection speed) to be more consistent
Sophisticated hardware design	Operates with low power consumption
Conforms to plug-and-play requirements	Permits easy installation and operation
Supports the same programming interfaces as other Dialogic Diva Media Boards, including Dialogic Diva APIs, CAPI, TTY, COM port, and others	Reduces porting efforts and time to market by making Diva Media Boards compatible with notable standard telephony and communications applications
Four Diva V-xPRI Media Boards of the same or different capacity can operate concurrently in a single server, depending on slot availability	Easy scalability and flexibility to address an organization’s fixed and GSM modem needs in diverse environments
Enable modem ports via license	Cost effective way to scale
