Dialogic Boards

CG Boards

The CG Series Media Boards can be used to create powerful communications solutions for public telephone network, IP-only, and converged IP/circuit-switched environments. By using these boards with Dialogic® NaturalAccess™ Software, developers can rapidly build and globally deploy a broad range of telephony applications on a single platform.

The CG Series Media Boards provide full-duplex universal port capabilities, which can support a combination of voice play/record, tone detection/generation, echo cancellation, and voice compression, as well as trunking, fax, conferencing, and VoIP functions in a single PCI, CompactPCI, or PCI Express slot. The universal port feature eliminates the need to use multiple specialized boards, provides easy access to all supported features, and significantly reduces the time spent on configuration and development.

Because they support up to 16 PSTN trunks and are equipped with high-density Digital Signal Processors (DSPs), high-speed PowerPC co-processors, and built-in IP capabilities, the CG Series Media Boards are an excellent option for a variety of applications from small enterprise call centers and announcement servers, to powerful, high-density service provider ring-back tone platforms and media servers.

GC Board Features
