Theory of Operation
The ICRI is capable of bridging, or linking, the voice communications between several radios, and
other voice sources.
The sources may include:
• Two-way radios (portable, mobile, narrow band/wideband).
• Telephone (land-line, cellular, satellite)
• Voice Over Internet Protocol (VoIP)
• Handset/headset
The ICRI permits these sources to be linked in one or two nets/talk groups according to the
operational requirements of the Incident Commander. The participation, of each agency’s radio or
other voice communications devices in a net/talk group, is controlled by a toggle switch for each
voice device connected to the ICRI.
The voice received from a remote voice source is utilized by the ICRI to “key” all other connected
devices. As audio is received from the radio or other device, the other devices in that radio’s
assigned net/talk group are “keyed” and the audio is released to these devices for transmission to
users monitoring these devices.
• An ICRI contains up to six (6) circuits that key the radios connected to the ICRI; these circuits
are commonly referred to as “VOX” or “voice-activated switches.” The ICRI uses these circuits
to perform other controlling functions as well. Only the VOX directly connected to the
incoming audio is used to key each of the other radios simultaneously (all other are temporarily
disabled, preventing a second “voice” from causing a disruption in initial voice being
distributed).
• There is no discrimination or evaluation of the incoming audio so that delays are not inserted
into the audio transfer or “keying” processes. Radios, telephones and/or recording devices
connected to the ICRI are provided with the incoming essentially in real-time (an initial delay at
keying to preserve the first syllables of incoming audio as the transmitters [including wide area,
repeater-based “trunked” radio systems] are keyed up).
All radio connections/ports on the ICRI are “universal”; any radio can be connected to any port
without special adjustment. Radio interconnect cables provided with the ICRI are engineered for the
radio brands/models, and along with circuitry within the ICRI, adjust for the difference that may
exist between radios.
Connection of mobile radios to the ICRI will not prevent the regular operation the mobile radio’s
hand microphone and speaker. This capability is derived from the design of the C-AT-supplied,
radio interface cables.
Initial connection of voice devices is aided by LED indicators for each connection/port. The LED is
an indicator of audio input to the ICRI and is used to initially set the radio output level to the ICRI.
This adjustment is made without meters or other instruments; an Automatic Level circuit in the
ICRI, that requires no user involvement, aids in this.
Each net/talk group can be independently set for a trunking system or repeater that has an access
delay. Generally, the setting of the delay by C-AT will never need to be adjusted.
- 4 -
The ICRI’s efficient circuit design permits a wide range of input voltages, 6-24V DC, will power the
ICRI without degradation of its capabilities/function.
In order to withstand the demands of harsh environments, the ICRI has been built into a waterproof
and dustproof Pelican case with waterproof connectors.
OPTION: Extension cable reels for radio interface may be supplied with this ICRI. The extension
cable permits a radio to be placed at this distance from the ICRI. This may be useful when
connecting to a satellite antenna/radio or when a team enters a structure/tunnel. Multiple extension
cable reels can be connected for even greater distance (up to 5,000 feet).
OPTION: Each Talk Group can be monitored through self-amplified, external speakers, when jacks
are added to the ICRI. These jacks can be installed on the left side of the ICRI. The jacks can also
be used for recording the communications on each Talk Group. The audio level is optimized for the
input to a digital recorder.

INTEROPERABILITY DOS AND DON’TS
These “universal” rules will help to ensure that the part of communications interoperability will
work properly.
1. Maintain COMSEC when forming interoperability bridges. Only connect Red to Red and
Black to Black.
2. Verify that only one interoperability bridge in the area is using the radio frequencies that
you will be using.
3. Audio and RF cables should be separated from AC power cables by 12” (use an external
DC source or batteries when you cannot maintain the separation).
4. When plugging in two or more radios within the same radio band (i.e. VHF) into a radio
bridge, like the ICRI, provide as much vertical separation as possible to reduce the
chance for interference due to the transmitted signal from one radio reducing the receive
sensitivity of the other “in band” radios. Consider using external mobile antennas
connected to the radios if necessary. Use only bridge interconnect cables that are well
shielded.
5. Some bridge cables contain in-line, audio amplifiers for radios designed with low audio
levels. It is best to route those cables away from radio antennas and connectors---high RF
fields can distort the audio amplifier’s output to the bridge.
6. Don’t use “SCAN” mode for any radios connected to a radio bridge. This is particularly
important when you are using the bridge as a tactical repeater, where two or more radios
have similar channel programming. If both radios are capable of hearing the same signal,
they will key each other up, known as "Ping-Pong,” interfering with the function of the
bridge.
7. Connecting two or more radios operating in the same band (VHF or UHF for example) to
a gateway will result in the “desensing” of the radio receiving a signal from a hand-held,
or mobile. Desensing may result in distorted audio from the receiving radio to the
gateway, and/or reduction of the radio’s ability to received signals from distant radios
(reduction in receiver sensitivity due to other radios transmitting very close to the
receiving radio). To lessen the severity of desensing, provide as much vertical separation
between the antennas of two or more radios operating in the same band.
- 6 -
Pre-Operational Activities
Some pre-planning is necessary to ready the ICRI for use. The following should be accounted for
before placing the ICRI on-line:
1. Determine what the power source will be for the ICRI and verify that the cable or battery
pack is available.
2. Predetermine what brand and model of radios will be connected to the ICRI and that an
“interconnect” cable for each radio is available.
3. Agencies must be advised that they will need to supply a “spare” radio, for the radio
interoperability, that the radio supplied must be known to operate properly and have at least
one fully charged battery.
The ICRI can be powered by internal batteries (8 “AA” batteries) or another DC source up to 20
VDC. The LEDs on the ICRI provide information battery status, in particular, a reliable indication
of a low voltage condition.
Note: If eight “AA batteries are used, the ICRI will continue operate to nominally for at least 2
hours after the “OK” LED is extinguished and the “LOW” LED has lit and then extinguished
(batteries will provide a reduced duty cycle due to low quality, poor storage conditions before use,
and/or low temperature during use).
Among the other power sources that can be used to power the ICRI are:
• 12 or 24 volt vehicle battery
• Vehicle cigarette lighter
• 115VAC (with an external adapter)
• Commercial dry-cell battery (12V or greater)
• C-AT 12 volt battery pack (uses 8 “AA” batteries)
• BA590 or similar “military”
The internal regulated power supply of the ICRI is both reverse polarity protected, but it is important
to check polarity of DC supplies before connecting them to the ICRI.
Note: The ICRI power input connector information appears on the bottom of the ICRI and in the
APPENDIX D: ICRI Chassis

“RAPID DEPLOYMENT” SETUP AND OPERATION OF THE ICRI
Setting up the ICRI for use with portable radios.
1. Place all Talk Group switches in the TG or 1 2 position.
2. After connecting a power source to the ICRI, turn on the ICRI so that power up and input
voltage can be verified. The green LED, labeled “OK” should be lit.
If you need to use a DC source voltage between 6.5 and 7.4 volts, then neither the OK nor
the LOW (voltage) LEDs will be lit, but the ICRI will be working.
3. Connect the handset to the ICRI handset jack. This is the jack, on the outside of the unit, that
is furthest to the left.
4. Connect the radio interface cables to the ICRI jacks labeled “1” through “5”.
All five ICRI radio interface connections (1-5) are electrically identical, so it is not
important which jacks are used for conventional, trunked, repeated, encrypted or mobile
radios during ICRI operation.
5. Connect the radio interface cables to the radios.
6. Verify that the radios are on the channels assigned to the interoperability/bridging function.
7. Select the Talk Group assignment for each radio, and place the switch associated with jack
into the designated Talk Group position.
The TG or 1 2 position of the switch places any item connected with the associated port into “NO
CONNECTION” conduction without physically disconnecting the device from the ICRI.
8. Turn on the radio connected to the jack labeled “1”and initially place the radio volume
controls at a mid-position between fully counter-clockwise and fully clockwise.
9. Place the handset Talk Group selector switch in the same Talk Group as the radio connect to
jack “1” so that you can transmit on that radio. You will also be able to monitor that radio.
10. As a radio connected to the ICRI receives voice for a remote radio user for the first time,
adjust the radio’s volume control so that the associated LED, above the jack, flickers as
words are spoken. The LED should not remain on continuously as the voice is received.
11. Repeat steps 8 - 10 for each radio connected to the ICRI
12. Connect the telephone, if it will be used.
13. Select the talk-group the telephone and/or handset will be associated with. Place the
telephone in the “OFF HOOK” position.
Refer to Optional SATPHONE, Land-line Telephone, Cellular Phone Interface for
detailed telephone interface application.

Setting the radio to pass audio to and from the ICRI
1. Set the radio to the desired channel.
2. Set the radio to the talk group designated by the Incident Commander.
3. Set the audio level on each connected radio to mid-position. The radio port’s associated LED,
located on the top deck of the ICRI, will light as the received audio passes from the radio to the
ICRI.
NOTE: When the ICRI is connected to the radio via its speaker/mic jack, the radio’s internal speaker and
mic are disabled. You will be unable to hear or speak through the radio. If you can hear or talk through
the radio, the cable may not be properly attached to your radio.
Troubleshooting radio connection with ICRI
NOTE: Before proceeding, refer to the INTEROPERABILITY DO’S AND DON’T’S for interoperability
guidelines…the solution may be there.
1. Connect the ICRI handset to the handset jack on the exterior of the ICRI.
NOTE: The plug on the handset appears to be similar to those provided for the radio interface cables, but
it will only work properly in the ICRI’s HANDSET jack.
2. If you have multiple radios connected to the ICRI, select one radio and turn it on. Turn off all other
radios or audio devices.
3. Verify that the volume control on the radio is set to mid position.
4. Depress the P-T-T bar on the side of the handset and hold it down while you speak into the handset
microphone. You should hear clean audio transmission through speakers on the radios in the same
channel as the radio connected to the ICRI.
5. Conversely, when you key another radio on the same frequency/channel as the radio connected to
the ICRI and speak into its microphone, you should hear a clean audio transmission through the
ICRI’s handset earpiece.
6. If you are unable to hear a clean audio transmission (a) verify the connections to the radio and ICRI
are secure, (b) the radio is indicating that it is receiving a signal from the remote radio.
Correct/adjust as needed.
7. Next verify that the LED on the ICRI flickers with each word spoken by the remote radio user. If it
does not, slowly turn the volume control on the radio connected to the ICRI clockwise, stopping
when the LED flickers as the remote radio user speaks.
8. If the lack of audio at the handset is not resolved, contact C-AT Technical Support at email:
[email protected]; support is available 24/7/365.

ICRI Local Handset
The handset can be used as a local incident command radio or a troubleshooting device. Up to 250’ of cable
maybe added to the cable length.
Setting up the handset
1. Plug the handset into the handset jack on the exterior of the ICRI. This is the jack, on the outside of
the unit, that is furthest to the left. When connecting the handset, make sure to align the flat side of
the handset connector with the orange dot on the handset jack.
2. The audio level to the handset speaker can be adjusted by the rotating the volume knob above the
jack. Counterclockwise decreases the listening level, and clockwise increases the listening level.
3. Set the audio level to mid position.
4. Select the talk group you will be listening/talking to and set three-position-switch above the handset.
5. The handset microphone is enabled when the push-to-talk bar on the side of the handset is depressed
and held down.
Disconnecting the handset
1. To remove the handset for storage, push inward on the handset connector and turn counter clockwise
to release the locking mechanism.
2. Then pull the connector straight out of the jack. Hold the barrel of the connector rather than the

Syllabic Rate Squelch System
Introduction
The syllabic rate squelch system (part # 500.3500) for use on voice radio circuits in lieu of the
conventional amplitude based squelch circuits found on most HF radios. Often times setting the
amplitude based squelch circuit on an HF radio to a level required to mute the noise found on most HF
frequencies results in the loss of weak signal reception. The device attempts to overcome this deficiency
by responding to certain speech characteristics as opposed to signal amplitude. The design is such that
very weak voice signals will enable the speaker audio while a degree of immunity to noise is provided
which reduces operator fatigue.
Theory of Operation
Sample un-squelched fixed level audio is fed to the sample audio input of the squelch module. This
audio is divided into two audio frequency bands via a low and high pass filter. The low pass filter passes
audio below 1500 Hz. The high pass filter passes audio above 1500Hz. The output of the two filters is
rectified and summed to produce a zero output voltage when energy in the two bands is equal. (noise).
When speech is present more energy appears at the output of either the high or low pass filter resulting
in a corresponding voltage at the output of the summing circuit. This voltage is subsequently fed to an
additional low pass filter with a cut off of approximately 10Hz. The 10Hz frequency is chosen to
approximate the syllabic rate of normal speech. When a voltage variation at less than 10Hz (speech) is
detected by this filter the output goes high. This output is then fed to a relay which closes and enables
speaker audio to pass.

APPENDIX A: Radio Extension Cable Reel
250’ and 500’ Radio Extension Interface (Cable Reel) P/N: 179.6214 and 179.6211
Positioning one or more of the radios, to be connected to the ICRI at a distance greater than the length of the
interface cable may be desirable for one of several operational reasons:
1. The personnel associated with a radio will be located inside a building for which there is poor RF
coverage from the ICRI’s location.
2. The personnel associated with a radio will be located inside a tunnel or other below grade area for
which there is poor RF coverage from the ICRI’s location.
3. Radios operating in very close proximity to one another, negatively affect the performance of other
another, such as receiver desensing.
The personnel—equipped with compatible radios—in the same general location of the reel-mounted radio,
will be able to communicate with those operating radios or the handset also connected to the ICRI.
The extension cable is inserted between the ICRI and the radio interconnects cable that is usually connected
directly to one of the radio ports on the ICRI front panel.
NOTE: Multiple reels of cable can be linked together for requirement of greater distance than 250 feet.
There will be no degradation of the communications link for up to 5,000 feet of cable, BUT it is important to
note that if the cable is run near a source of high electrical energy, “noise” from such a device can be
expected to be induced into the cable and reduce---possibly significantly---the quality of the
communications.
It is strongly recommended that the radio link be tested before the personnel enter the area of poor RF
propagation, so that any defects with the cable or the connections will be noted before a safety issue arises--
due to a lack of radio communications.

Set-up of the cable-reel
Equipment required: ICRI, cable-reel, radio interface cable for radio to be placed in the area of poor
RF coverage.
1. Place the radio on the hub/support and secure it in-place with the Velcro™ strap.
2. Connect the cable end that exits from the side of the reel to the radio interface cable. Be sure
to align the flat surface of connector to red dot on the selected ICRI port. Push the cable
onto the jack and turn clockwise until cable locks in place.
3. Connect the other end of the cable to a radio port on the ICRI. Be sure to align the keyway
and secure the connectors together with the locking ring on the male connector.
4. Before entering the confined space, verify that the radio link between the entry team and the
radio connected directly to the ICRI is operating properly.
5. If needed, connect additional cable reels between the ICRI and the first reel (up to a total
distance of 5,000 feet).
NOTE: If the cable will be used to place a radio in a stairwell, or on a building roof, hill or tree
top to enhance the operating range of the radio, then it may be preferable to have the cable reel
located beside the ICRI and the radio connected to the unspooled end of the cable. In this case
reversal cables are needed.
Set-up of the cable-reel with reversal cables:
Attach one end of cable “A” to the male connector located near the center hub on the reel. Attach
the other end of cable “A” to an ICRI radio port.
A
Attach one end of adapter “B” to the female connector at the “free” end of the cable. Attach the
other end of adapter “B” to a radio interface cable.
B
With this configuration, the cable reel will remain with the ICRI unit and the radio would travel to
the incident site or remote location for better operating range of the radio.
