Upon selecting the items, the system software will place the items on the screen showing the ICONs as connected. For example, if the user wants to create a Talk Group, the user touches the TG ICON at the bottom of the display and touches the items to be connected, from the top of the screen. As the items are selected they are displayed on the monitor screen. As shown in the figure, Talk Group No. 1 has two radios, one phone and one computer connected. After selecting the items to be connected the user simply touches the connect ICON and the items are ready for operation. 

The RIOS uses the Windows 2000 or Windows XP Operating Systems, which provide a familiar and user-friendly environment. 

The SyTech SR-3001 Radio Inter Operability System (RIOS) allows for the ability to communicate between any types of dissimilar communications systems, e.g. radios, telephones, computers and other forms of communications systems may be connected into “Talk Groups”. In addition to voice communications, the RIOS will also allow for data inter-operability, using 802.XX technology. 

The RIOS consists of a computer, I/O chassis and the inter-connecting radios. Two configurations are available, (1) portable and (2) rack mount. The portable is small enough to be carried on a commercial airliner as checked baggage and can be easily configured in a vehicle such as a Suburban or any SUV. The I/O chassis provides for a DC input from the vehicle 12-volt system. The portable is typically used with portable hand held radios. The rack mount unit is typically used with land mobile radios (LMRs), thus increasing output power. LMR’s that are computer controlled may be controlled from the dispatcher console, thus allowing for the dispatcher to remotely control the frequency of the radios. This remote radio control allows for the RIOS to have the frequency of the gateway radio match the frequency of the field radios. 

The communications between the radios is controlled through the use of a PC computer and SyTech designed and developed software. The software is used to setup communications links between any types of communications systems. The RIOS will allow for the full capabilities of a dispatch center (telephones, radios and data). The main computer functions both as the database and recorder server. Additional PC’s can be connected via a LAN as client stations. These client stations have the full and complete suite of software to allow for the control of all communications. As audio from the communications is being recorded, the radio dispatcher/controller may also view the radio data (e.g. Caller I.D., start time, duration, etc). Audio is recorded immediately to the archive media, magneto optical or DVD. Available to the radio dispatcher/operator is the full suite of the Advanced Digital and Analog Collection (ADACS) analysis software. After the call has ended, the operator may play back the call and use MS Word to provide a complete transcription of the recorded call. The playback audio is displayed as a frequency spectrum. This frequency spectrum allows the user to identify speakers or allows for forensic analysis. A remote computer may be connected to the system through the use of high-speed WANs or Plain Old Telephone Service (POTS) lines. The system is fully compliant with all police, fire and EMS radio communications. A report writer-generator allows for the automatic creation of any reports required by Police or Fire Departments. For example, Traffic Reports and Individual User Reports are fully automated. SyTech provides for 24 X 7 maintenance support and continuous software upgrades for new radios. The major features of the RIOS are:
 

• User Friendly Graphical User Interface – All “Talk Groups” are shown as star clusters. Talk Groups are established by simply selecting the function and selecting the communications system. Operators learn to use the RIOS in minutes. 
• Ability to Control Radio Frequencies (channels) Remotely – The RIOS may be configured with radios that are computer controllable. When an agency arrives at the incident site, the RIOS radio is changed to the appropriate frequency. 
• Ability to Act as Repeaters – All RIOS channels have the ability to act as repeaters and have full control of all incoming and outgoing radio traffic. Multiple RIOS at an incident site are all "meshed" thus you have built in redundancy. 
• Dispatcher Capabilities – All RIOS have the main functional capabilities of a dispatcher station, i.e. receive and transmit radio channels and all transmissions may be recorded and played back, (911 requirement). A number of our customers use the RIOS in command vans as back-up 911 centers. 
• All Channels are Re-Configurable – all channels are "re-configurable" on the fly. Any radio maybe connected to any channel. Other systems are hardware dependent, thus channels are radio specific. 
• Integrated Voice and Data – When using multiple RIOS, communications maybe via radio (voice) or a wireless data connection, e.g. 802.XX or any wireless integrated network. This communications capability is extremely useful in "incidents". Command and Control on the ground must be maintained on a "Real Time" basis. 
• Audio Store and Forward – Channels interface with radio trunking systems intelligently. The RIOS will wait for acknowledgement before passing the audio to non-trunking systems, thus no audio is lost. 
• Built in Digital Recording & Traffic Analysis – The RIOS computer has a built-in digital recording capability. Audio and data are recorded to the hard drive and archived on a permanent basis to archive media such as DVD. 
• No Limit on the Number of Talk Groups – There is no limit on the number of Talk Groups. The number is only limited by the number of channels available on the system. 
• Permanent Archiving – Audio and data may be permanently archived to a 2 bay DVD array. 
• PC Remote Client –This module allows remote users to control and communicate with the RIOS server via an 802.11 wired or wireless network.  Remote users can perform all functions. 
• PDA Remote Client Module - Same capability as the PC Remote Client but adapted to the limited resources of a PDA. 
• PBX – This option can be packaged in a separate box or integrated into the RIOS case to provide connections for standard analog, digital, or VoIP phones. 
• Automatic Report Generation – System has ability to produce reports automatically. Reports will provide the time of all transmissions, incoming or outgoing, length of call, time of call and other call record data.
