IntegrIT CFSI Analog – is a functional component for conventional fixed radio station implementing Conventional Fixed Station Interface (CFSI), which often referred as Tone Remote Control (TRC) and allows glue less integration with analogue FM and digital APCO P25 radio stations. Strictly confirmed with TIA-102.BAHA CFSI Analog provides voice transferring, TRC and intercom capabilities.
Features
- Transport of clear audio between a fixed station and its host, providing capabilities for full-duplex, half-duplex and simplex communications at the discretion of the fixed station.
- Transport of E&M control signaling between a fixed station and its host to provide a simple “Push-to-talk” and “COR” capability.
- Transport of Tone Remote Control (TRC) control signaling from a host to a fixed station to provide a variety of control functions including transmit channel control, squelch control, monitor control, clear/secure controls, analog/digital mode controls, etc.
- A primitive “Intercom” capability allowing for the transport of audio between the fixed station and its host without initiating an RF transmission
Applications
- APCO P25 equipment
- Software Defined Radio
- Base-stations and repeaters
List of supported platforms:
- Texas Instruments TMS320C55xx, TMS320C64xx, DaVinci, OMAP
- ARM9E
- x86

IntegrIT CFSI Digital – is a functional component for conventional radio station APCO P25 implementing digital Conventional Fixed Station Interface (CFSI). CFSI Digital complies with TIA-102.BAHA and allows sending/receiving voice and data traffic to/from air, remote control and configuring (PTT, Caller ID, Talk-group, NACs, emergency indication, voter identification) and provides Intercom capability. CFSI Digital uses UDP/RTP as a transport for communication with host console.
Features
- Transport of clear full-duplex audio between a fixed station and its host
- Transport of encrypted audio between a fixed station and its host
- “Intercom” capability allowing for the transport of audio between the fixed station and its host without initiating an RF transmission. G711 is used for intercom.
- Glue less integration with IntegrIT APCO P25CAI
- Support of G711/IMBE vocoder formats in RTP stream for sending voice traffic in air
Applications
- APCO P25 equipment
- Software Defined Radio
- Base-stations and repeaters
List of supported platforms:
- Texas Instruments TMS320C55xx, TMS320C64xx, DaVinci, OMAP
- ARM9E
- x86

Software platform to build portable and mobile DMR (digital mobile radio) stations
 IntegrIT DMR is a software stack implementing Digital Mobile Radio (DMR) Air Interface (AI) protocol Layers 1 and 2. It employs Time Division Multiple Access (TDMA) technology with a 2-slot TDMA solution and RF carrier bandwidth of 12,5 kHz. Additionally, for Tier I products it employs a continuous transmission variation (FDMA) of the above mentioned technology. Strictly conformed to ETSI TS 102 361-1 specification, IntegrIT DMR is an ideal solution for OEM 2-way radio equipment manufacturers. It is scalable to fit in portable and mobile radios as well as base stations and repeaters. Robust decoding technique provides superior performance in noisy environment. Modular architecture and message based organization allow for manufacturers to extend their analogue radios with DMR functions at a reasonable efforts.
Features
- ETSI TS 102 361-1 interoperable (Tier I and Tier II). Can be used for conventional and trunking communication, in digital repeaters and base stations as well as portable and mobile radios.
- most DMR modes supported (full/half duplex, TDMA/FDMA)
- mixed voice/data operation
- glueless interface to external DVSI AMBE-3000 decoder chip or AMBE library
- robust MLSE equalization together with soft-decision decoders for better radio performance
- extensive self testing and logging capabilities
Applications
- Public Safety
- DMR equipment
- UHF 2-way radios
List of supported platforms: - Texas Instruments C674x/OMAP13x, TMS320C64xx, DaVinci
