Overview:

The Dialogic D/480JCT-2T1 Media Board is a 48-port Digital T1 PCI Express board and the Dialogic D/600JCT-2E1 Media Board is a 60- 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.

Features and Benefits:


Features Benefits
48 to 60 independent voice channels, and 24 to 48 T1 or 30 to 60 E1 network channels in a single PCI Express slot Lower costs while creating larger high-density systems with fewer boards per chassis
