The radio interface unit (RIU) is one of the SwitchplusIP core building blocks and provides a seamless interface between radios and telephony assets using open standards VoIP technology.
It provides support for four programmable audio devices, each with its own serial port for configuration or data transmission, allowing to connection to landline telephones, mobile phones, handheld radios and radio systems.
It uses dedicated DSP audio processing resources to efficiently convert the audio from these devices to standards-based VoIP, which can be streamed to any compatible device via the LAN. It also supports dual LAN interfaces ensuring that mission-critical audio always gets through to its destination.
The RIU can be used standalone as a SIP-based RoIP gateway, integrated with other open standards type solutions such as RTP (Wave) or as part of a larger total C4i communications solution. It is suitable for vehicle interoperability solutions, mobile fly-away kits and anywhere that needs extensive capability in a small ruggedised footprint.
