The DNI Half Length Boards are standard-height PCI Express format providing a native PSTN interface to Dialogic® PowerMediaTM Host Media Processing (HMP) Software. These half-size DNI Boards can 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 DSI SS7 Protocol Stacks, allowing combining HMP media on the host, with SS7 signaling on board. DNI Boards enable efficient VoIP gateway functionality to be built into PowerMedia HMP telephony applications. They also break 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 capability.
