High Density Modems - V-xPRI E1 / T1 Modem Boards - PCIe

Diva T1/PRI/24M

Overview

Available in 1, 2, 4 and 8E1 variants the Diva V-xPRI Media Boards offer the scope to build high density modem banks with up to 240 ports in a single server. Ideal for a variety of applications ranging from point of sale termination through to monitoring and termination of utility metering devices.

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

Key Features

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 standards

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

Up to four or more Diva V-xPRI Media Boards of the same or different capacity can operate concurrently in a single server, depending on the application and performance of the server hardware

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
