Dialogic High Density Modem
支持最大120，全功能的 V.90 or 240 V.32 通道。
介绍
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
- Conforms to plug-and-play standards
- Enable modem ports via license
- Reduces porting efforts and time to market by making Diva Media Boards compatible with notable standard telephony and communications applications
- Supports the same programming interfaces as other Dialogic® Diva® Media Boards, including Dialogic® Diva® APIs, CAPI, TTY, COM port, and others
- 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
- Operates with low power consumption
- Permits easy installation and operation
- Cost effective way to scale
- Easy scalability and flexibility to address an organization’s fixed and GSM modem needs in diverse environments
