Overview:

The Dialogic D/240JCT-T1 Media Board is a 24-port Digital T1 PCI Express board and the Dialogic D/300JCT-E1 Media Board is a 30- port Digital E1 PCI Express board. Both of these boards are well-suited for developing advanced communications applications requiring digital network interfaces as well as multimedia resources. These high performance, scalable products support voice, fax, and softwarebased speech recognition processing in a single PCI Express slot.

Dialogic JCT Media Boards – including these models - can be used by developers to provide small- and medium-sized enterprise Computer Telephony (CT) applications that require high-performance voice and fax processing. Among the features and benefits of these boards, and other Dialogic JCT Media Boards, are the following. They have On-board Digital Signal Processor (DSP) based voice processing technology and they are well-suited for server-based CT systems under Windows and Linux. They also provide a powerful platform for creating sophisticated Interactive Voice Response (IVR) applications for the small and medium-sized enterprise market segment. Features such as fax and software-based speech recognition processing enable unified messaging applications. They also provide Automatic Gain Control (AGC), so even a weak telephone signal can be recorded and replayed with clarity.
