THEORY OF OPERATION
The next set of slides will provide a broad overview operational capabilities of the ICRI. Setup and operation will be discussed in greater detail in the following slides.

12. Description-Pt. 1
A small, lightweight interconnect assembly for “bridging” dissimilar radios
The ICRI performs two primary functions:
Receive incoming audio
Distribute audio
Quick Setup
VOX Keying
Description Part 1
A small, lightweight interconnect assembly for “bridging” dissimilar radios. The ICRI is capable of bridging, or linking, the voice communications between several radios, and other voice sources.
Dissimilar radios can include:
Varying models/frequencies,
Clear/encrypted radios,
Talk-around/trunked radios
Portable, mobile, narrow band/wideband
Telephone (land-line, cellular, satellite)
Voice Over Internet Protocol (VoIP)
Handset/headset
The ICRI performs two primary functions which will be described in further detail in the next slide:
Receive incoming audio. Incoming audio from one radio or telephone “keys” the other radios connected to the ICRI.
Distribute audio. The incoming audio is then distributed to the other connected radios operating on different frequencies, telephone or recording device connected to the ICRI and broadcast over those additional frequencies.
Quick Setup. Provides for quick set-up and extended operation without additional power or equipment in harsh operating environments.
VOX Keying. Each audio input port, except the telephone port, uses a voice activation “radio key” and receive priority circuitry.

14. Description-Pt. 2 Description Part 2
The ICRI can support communications links between radios like the M/A Com P7100, Motorola XTS5000 radios and legacy radios operated by federal, state and local agencies. Mobile radios may also be connected to provide long range communications. Radio connection to the ICRI is via speaker mic port or handset port of the radios.
Frequency/channel selection. The ICRI is not an RF device. It uses the radios connected to the ICRI to transmit and receive audio. The frequency/channel of the connected radios are the frequency/channels that the ICRI will patch.
Use supporting teams radios. Because the ICRI is not an RF device, one radio from each participating agency is connected to the box. There are no modifications that need to be made to the radios or the ICRI to create a patch.
External speaker mic connection. The ICRI uses the speaker mic jack on the radio to access the audio path and keying, this is done through an interface cable from the radio to the ICRI. These connections are generally propriety to the radio manufacturer. The most common radio interface cables are the Motorola XTS and HT series radios, operations with military partners generally require a “green gear” (SINCGARS) radio interface. Discuss with the agencies you are likely to work with to determine which radio interface cables you will need.
Ports are not radio specific (mobiles or portables). The radio ports on the ICRI are identical in function and do not require programming for function. Any radio maybe placed in any of the radio ports without change in function.
User instructions on top cover. Abbreviated user instructions are printed on the top cover of the ICRI. While this is not a substitute for the user manual, it will provide more than adequate information for an individual with minimal experience to setup and operate the ICRI.
Interconnect cable technical notes on bottom cover. Technical notes on the cable pinouts for field repairs if needed. Expanded documentation is available in the user manual.

15. Interoperability Do’s and Don’ts
Maintain COMSEC
Verify only one bridge connected on frequencies
Maintain RF Separation
Power sources
Other radios
In-line audio amplifiers
Don’t use “SCAN” mode on connected radios.
INTEROPERABILITY DO’S AND DON’TS
There are several important considerations when setting up an interoperability bridge that will improve the effectiveness of the bridge and your radios.
Maintain COMSEC. When forming interoperability bridges verify that only encrypted radios are connected to other encrypted radios and at the same level of encryption.
Verify only one bridge connected on frequencies. Verify that only one interoperability bridge in the area is using the radio frequencies that you will be using.
Maintain RF Separation.
Power sources. Audio and RF cables should be separated from AC power cables by 12” (use an external DC source or batteries when you can’t maintain the separation).
Other radios. 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. Consider switching to a NIPSPAC frequency
In-line audio amplifiers. Some bridge cables contain in-line, audio amplifiers for radios designed with low audio levels. It is best to rout those cables away from radio antennas and connectors---lots of RF and distort the audio amplifier’s output to the bridge.
Don’t use “SCAN” mode on connected radios. 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 "ping-pong", interfering with the function of the bridge.

16. Setup and Operation
THEORY OF OPERATION
The following slides will provide a broad overview operational capabilities of the ICRI. Setup and operation will be discussed in greater detail in the following slides.

17. Preoperational Activities
Power
Radio interconnect cables
Agency radios
Radio frequency (in- band/cross-band)
Preoperational Activities
Before setting up the ICRI for operation, determine how the ICRI will be setup.
Power. Predetermine what the power source will be for the ICRI and verify that the cable or battery pack is available.
Radio interconnect cables. Predetermine what brand and model of radios will be connected to the ICRI and that an “interconnect” cable for each radio is available.
Agency radios. Advice agencies 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.
Radio frequency (in-band/cross-band). Predetermine if multiple, in-band, radios will be bridged. This will be important in determining radio location to prevent desensing.

34. Common Options
THEORY OF OPERATION
The next three slides will provide a broad overview operational capabilities of the ICRI. Setup and operation will be discussed in greater detail in the following slides.

35. Cable reel
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:
The personnel associated with a radio will be located inside a building for which there is poor RF coverage from the ICRI’s location.
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.
Radios operating in very close proximity to one another, negatively affect the performance of other another, such as receiver desensing.

Connect the cable end that exits from the side of the reel to the radio interface cable. Be sure to align the keyway and secure the connectors together with the locking ring on the male connector.
Connect the unspooled 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.
If needed, connect additional cable reels between the ICRI and the first reel.

38. Reel link
Multiple reels of cable can be linked together. There will be no degradation of the communications link for up to 5000’ 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.

39. Cable Reel with Attachments
The cable reel allows the audio from radios located in an RF isolated area such as a building, tunnel or ship, out to the command post and radio network. Reels can be linked together for up to 5000’ range. Multiple reels can be run on the ICRI with separate radios.

40. Cable Reel with Reversal Attachments
The cable reel function can be reversed. Instead of bringing the reel and radio assembly into the desired location, the adaptors allow the radio to be remoted from the reel and carried in or lowered down while maintaining constant communications.

41. Optional adapters for cable-reel for vertical entries
Reversal cables invert connection ends of the cable reel

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.
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.
With this configuration, the cable reel will remain with the ICRI and the radio would travel to the incident site or remote location for better operating range of the radio.
When to use: Using the cable-reel to place a radio in a stairwell, on a building roof, hill or tree top to enhance the operating range of the radio, then it may be preferable to have the reel located beside the ICRI and the radio connected to the “free” end of the cable to be unspooled.

42. Bridge Unit ID®
In response to the critical disruption of radio communications that can occur when more than one "bridge" device links radios with identical frequencies, causing heterodyning, C-AT has developed the Bridge Unit ID for the ICRIs.
The “announcement” radically simplify the task of locating the owner of the interfering bridge and in shutting the device down.
The Bridge Unit ID is a digitized speech message selected by the user organization / agency. The “ID” is transmitted when the ICRI is first powered up on all talk groups, and then at preset intervals of 0, 5, 10, or 15 minutes.
The announcement automatically “skips” a
broadcast if there is any radio activity at the
interval mark.

43. Remote DTMF Control Functions Setup
There must be a radio connected to the Land Mobile Radio Interface #1 jack.
DTMF sequence for unit: __ __ __ __ _ _
10 All Off (Interoperability “bridge” disabled)
11 All inputs on Talk Group 1
12 All inputs on Talk Group 2
13 Re-enable “bridge”/Talk Groups
Remote DTMF Control
Some NJICS ICRIs are equipped with “remote control” of several functions; the control of these functions is made through the radio connected to ICRI PORT #1 and a portable radio with a12 button DTMF pad. A selected radio (VHF, UHF or 800mHZ) plugged into the ICRI PORT labeled “1” is the “control” radio and a valid coded DTMF entry will “control” the programmed functions of the ICRI. This function will work only in PORT 1.
If the “remote control” functions may be required during the operation of the ICRI, then verify that the radio connected to ICRI PORT #1 is active and that the Incident Commander or other designated responder has a two-way radio the can “talk to” the radio in PORT #1 and that the individual’s radio is equipped with a functioning DTMF pad.

The ICRI Remote DTMF Control Codes may vary slightly by agency and should be verified with your unit.

49. Interoperability Do’s and Don’ts
Maintain COMSEC
Verify only one bridge connected on frequencies
Maintain RF Separation
Power sources
Other radios
In-line audio amplifiers
Don’t use “SCAN” mode on connected radios.
INTEROPERABILITY DO’S AND DON’TS
There are several important considerations when setting up an interoperability bridge that will improve the effectiveness of the bridge and your radios.
Maintain COMSEC. When forming interoperability bridges verify that only encrypted radios are connected to other encrypted radios and at the same level of encryption.
Verify only one bridge connected on frequencies. Verify that only one interoperability bridge in the area is using the radio frequencies that you will be using.
Maintain RF Separation.
Power sources. Audio and RF cables should be separated from AC power cables by 12” (use an external DC source or batteries when you can’t maintain the separation).
Other radios. 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. Consider switching to a NIPSPAC frequency
In-line audio amplifiers. Some bridge cables contain in-line, audio amplifiers for radios designed with low audio levels. It is best to rout those cables away from radio antennas and connectors---lots of RF and distort the audio amplifier’s output to the bridge.
Don’t use “SCAN” mode on connected radios. 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 "ping-pong", interfering with the function of the bridge.
