Dialogic DNI Media Boards


Dialogic®'s DNI E1/T1 Media Board Range offer an extremely versatile platform which can be used in conjunction with Dialogic®'s PowerMedia™ Host Media Processing (HMP) software for easy implementation into any communication infrastructure. Available as a single E1/T1 to up to 8 E1/T1, the DNI boards support onboard G.168 echo cancellation, enabling efficient VoIP gateway functionality.

The DNI half-length boards are standard height PCI Express format providing a native PSTN interface to Dialogic® PowerMedia™ Host Media Processing (HMP Software). PowerMedia™ HMP performs media processing tasks on general-purpose servers without using specialised software, and provides media services for building flexible, scalable and cost-effective IP media servers. DNI boards and PowerMedia HMP can be combined to provide a cost-effective platform for converged TDM-IP applications.

The DNI range breaks the traditional DSP-based media span paradigm by providing a digital network interface ready for use with virtually any configuration of host-based media resources which complement the base gateway compatibility. Suitable to be used in place of full-size PCI Express format DNI boards of equivalent density in applications using PowerMedia HMP without programming changes, DNI boards are compatible with the Dialogic DSI SS7 protocol stacks, enabling users to combine HMP media on the host with SS7 signaling on the board.
