Description

Dialogic® Diva® V-xPRI Modem Board – High-density modem solution for versatile applications

The Dialogic® Diva® V-xPRI media boards enable the creation of high-density modem banks with up to 240 ports in a single server. Available in 1, 2, 4 or 8 E1/T1 port variants, these boards provide a powerful solution for point-of-sale systems, machine-to-machine (M2M) communications, network protocol testing, and utility monitoring and billing.

The Diva V-xPRI media boards support both Windows and Linux and emulate COM or TTY ports directly in the operating system. This means that existing modem and COM port applications can continue to be used without modification.

Optimized connection stability and transmission speed

With support for up to 120 full V.90 or 240 V.32 channels and FastConnect technologies for V.22, V.22bis and V.29, the board shortens connection setup times and increases the overall transmission rate per channel. These optimizations ensure higher efficiency and better performance in data-intensive applications.

Flexible application options in modern communication infrastructures

With its extensive modem protocol support, the Diva V-xPRI modem board is ideal for companies that require a scalable, reliable and future-proof solution for their modem communication. It enables secure and stable data transmission, especially in business-critical environments.
