SwitchplusIP
Radio Interface Unit (RIU)
Interoperability between you and other
agencies via open standards Voice over IP
Simplifying Radio Over IP technology
The RIU is one of the SwitchplusIP core building blocks and provides a seamless
interface between radios and telephony assets using open standards Voice Over IP
technology. Within its super compact, ruggedized footprint, the RIU provides support for
4 programmable audio devices each with its own serial port for configuration or data
transmission.
It uses dedicated DSP audio processing resources to efficiently convert the audio from
these devices to standards-based Voice over IP (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 Radio Over IP (ROIP) gateway, integrated
with other open standards types solutions such as RTP (Wave) or as part of a larger total
C4i communications solution. It is ideally suited for Vehicle Interoperability Solutions, Mobile
Fly Away Kits and anywhere you need extensive capability in a small ruggedized footprint.
Simplifying configuration
The RIU is extremely easy to configure. Using an intuitive web interface, users have access
to all of the advanced facilities of the RIU.
Simplifying connections
The RIU provides direct connection
interfaces to a range of audio equipment:
Conventional and trunked radios;
Public address systems;
Monitor speakers;
Intercoms.
Simplifying Interoperability
Connect your unit to the state police;
Your patrol officers to an EMS bike team;
The Chief s office to the incident ground; or
The Governor to the incident commander.
All simply done with C4i Products.
