4. Theory/Principles 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.

5. The 2P performs two primary functions:
Theory of Operation
The 2P performs two primary functions:
Distributes the audio received from a two-way radio, or telephone, to a second radio also connected to the 2P.
Utilizes this same incoming audio to “key” the other communications devices connected to the ICRI.
Description
A small, lightweight interconnect assembly for “bridging” dissimilar radios. Dissimilar radios can include varying models/frequencies, clear/encrypted radios, talk-around/trunked radios as well as land-line/cellular/satellite telephones.
The ICRI performs two primary functions:
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.

6. The “2P” can provide a communications bridge, or link, between two public safety agencies with otherwise incompatible radios; can quickly establish the link as a tactical situation rapidly unfolds; and requires minimal resources to enable it initially, or to maintain its operation over many hours.
The “radios” can be hand-held portables, vehicle or console radios, SPRINT/NEXTEL “Direct Connect” phones or a combination….conventional or trunked… land-line telephones, cell phones, STU, STE or satellite phones can also be connected to the ICRI.

7. The 2P will remain fully operational for 30+ hours powered by an external “AA” battery pack (8 “AA alkaline batteries), 10+ hours powered by the internal, rechargeable battery, and indefinitely when powered by an AC source.
The internal Lithium Ion battery will not provide a “low battery warning” (Green LED going off and Red LED coming on indicating 2-3 hours before battery charging/replacement is required). The “AA” battery pack will provide the transition.

14. Pre-Operational Activities
Some pre-planning is necessary to ready the ICRI for rapid deployment. The following should be accounted for before placing the ICRI on-line:
Determine what the power source will be for the ICRI. Verify that the internal battery is charged or that one of the external power source option are available.
Determine what brand and model of radios will be connected to the ICRI and that an “interface” cable for each radio is available.
If radios are not maintained with the ICRI, advise participating agencies that they will need to supply a “spare” radio, for the radio interoperability.
Verify that the radios are known to operate properly and have at least one fully charged battery or other reliable power source.
The ICRI’s internal regulated power supply is reverse polarity protected, but it is important to check polarity of DC supplies before connecting them to the ICRI.
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.

15. INITIAL SETUP
As a minimum, the following will be required for ICRI operation:
ICRI assembly
Charged internal Li Ion battery or external power supply with interconnect cable to ICRI
Two radio interface cables and/or a radio interface cable and a cell phone cable (no external cable needed for land-line phone connection)
Two radios and/or a phone

16. Determine power method and connect to ICRI, place the POWER switch in the “ON” position; the “OK” LED should be lit. If the Li Ion battery has been fully charged, it will provide at least 10 hours of continuous use.
Check the radios’ transmit and receive functions, battery and channel selection. Radios must not be in SCAN mode.
Connect one interface cable to the ICRI and one radio
Connect the handset.
Set the volume controls for the radios and handset to a position mid-way between fully CLOCKWISE and fully COUNTER-CLOCKWISE

Connect Interface cable. Install the radio-end of the ICRI interconnect cable onto the radio, as you would install other radio accessories (i.e.: a shoulder speaker / microphone).
Tightening any locking screws is optional; but it is important that the connector be firmly seated against the radio so that good electrical contact is made.
Attach the other end of the cable to any of the LAND MOBILE RADIO INTERFACE jacks.

26. Land Mobile Radio Interface
Attach interface cable
Set volume control to mid-position between fully CW and fully CCW
Verify VOX LED lights as voice is received at the radio
NOTES: Connecting each radio separately to the ICRI and using the provided handset allows you to verify the radio is functioning before connecting the next radio.
A radio’s internal speaker will be disabled when the interconnect cable has been attached, so you must use the handset, or a second radio on the same channel to verify the communications link.
Land Mobile Radio Interface – Pt. 2
Attach interface cable. Attach the interface cable to any of the LAND MOBILE RADIO INTERFACE jacks and a radio on the other end.
Select Talk Group. Talk group switches are inline with the corresponding jack. Set the talk group switch for each connected radio
Up: Talk Group One
Down: Talk Group Two
Center: no Talk Group connection (mute)
Verify LED lights. The LEDs directly above the radio ports in use should flicker as the radio is transmitting.
If they remain solidly lit, turn down the volume.
If they are not lit, turn the volume up.

27. To disconnect the connector for cable storage, push inward on the locking ring with minimal force, and at the same time turn the ring counter-clockwise 1/8 (45o) turn to release the locking mechanism. Then, holding the metal barrel of the connector, pull the connector straight out of the jack.

28. TELEPHONE INTERFACE
This jack supports the connection of the ICRI to a land-line telephone through the telephone’s handset wiring (using the coiled cord between the telephone’s base with touchpad and the handset) or the 3.5mm jack on a cell phone (using C-AT interconnect cable P/N ).
A phone connected to the ICRI will be used for dialing and other keypad functions since the speaker and microphone functions are disabled. Use the ICRI’s handset to talk/listen to the remote individual, if using the ICRI as a base station.

29. Telephone Interface – Land-line*
Use the telephone’s handset cable by unplugging the coil cord from the bottom of the handset and connecting to ICRI.
Place the telephone handset back in the cradle until an in-coming call is received or an out-going call will be made.
If the telephone permits conference calls to be setup, then all parties to the conference call can bee connect to the ICRI.
* Secure (STE) or non-secure (analog or digital)

30. Telephone Interface – Cellular*
When connecting to a cellular telephone using the interface cable, P/N , insert the 3.5mm (1/8”) plug into the headset jack on the cellular telephone. Be sure it is fully pushed into the telephone’s jack.
Set cell phone’s speaker/earphone audio to a mid-level setting following the cell phone manufacturer's instructions.
The cell phone should be in the "auto answer" mode. See phone's instruction manual for the procedure.
Dial a remote telephone or wait for an incoming call from another telephone.
To receive an incoming call, the phone must be set to auto answer, or an individual must be available to answer the phone by pressing SEND or equivalent.
If the cell phone permits conference calls to be setup, then all parties to the conference call can bee connect to the ICRI.
Telephone Interface – Cellular*
Insert the 2.5mm plug into the cell phone headset jack. Be sure it is fully pushed into the jack on the telephone. For cellular phones with a headset jack, use cable P/N and adapter P/N
Connect to ICRI. Connect the other end of the cable with the modular plug into the jack on the adapter.
Adjust volume to ICRI. Adjust volume to ICRI using cellphone “headset volume control
Set phone for auto answer. This will allow incoming calls to the ICRI to be received without someone physically located at the unit.
Place call. Note that the speaker and mic on the cell phone will be disabled once the headset adaptor is connected. Use the handset to talk through the cell phone.
*secure or non-secure

31. The Local Handset
The handset provides the user with a local interface to the ICRI, without using a radio. It will allow an individual to hear and respond to all audio transmitted through the ICRI from the radios and telephone connected to the ICRI.
Using the handset
Connect the handset to the jack labeled “Handset.” Make sure to properly align the pins of the plug before inserting into the jack.
After the plug is fully seated on the jack, the locking ring on the plug should be turned clockwise until the ring cannot be turned further.

32. Adjusting the handset/headset volume
The audio level to the handset speaker can be adjusted by the rotating the volume knob above the jack. Counterclockwise decreases the audio level, and clockwise increases the listening level.
Set the audio level to mid position.
The handset microphone is enabled when the push-to-talk bar in the center of the handset is depressed and held down while speaking

33. Switch position “Left”: BRIDGE ID ON
ICRI UNIT IDENTIFIER:
The ICRI has a “Bridge ID” announcement that is transmitted every 10 minutes unless disabled . Each ICRI has a unique ID (for example, “FAM Gateway Eleven”). This message will not be broadcast if the ICRI is receiving input (voice) from any of the devices connected to the ICRI--- the message will not interrupt any audio activity, but will wait for activity to cease before broadcasting. The Unit/Voice ID is also transmitted each time the ICRI is turned on.
If needed, this function can be disabled. This ICRI has a two position switch on the rear of the ICRI.
Switch position “Left”: BRIDGE ID ON
Switch position “Right”: BRIDGE ID DISABLED/OFF
After switching the ID message off or on, turn off the ICRI momentarily and then turn it back on---this resets internal circuitry.

34. *A “standard” CAT5 cable will not work.
ICRI-to-ICRI LINK
Connect the supplied “cross-over” RJ-45 cable, p/n *, between two ICRIs. Operate the ICRIs as normal. It is not necessary to power off or restart the ICRIs after connecting/disconnecting the link cable.
Radios connected to the ICRIs will all be bridged together, when the link cable is connected.
The distance between ICRIs cable can be extended by connecting a commercially availability CAT5 cable between one end of the “cross-over” cable and one of the two ICRIs to be linked.
*A “standard” CAT5 cable will not work.

35. Interoperability DOs and DON’Ts
These simple “universal” rules will help to ensure that the part of communications interoperability will work properly.
Verify that only one interoperability bridge in the area is using the radio frequencies that you will be using.
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).
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.
* HarrisTM - M/A COMTM P7100, P7200, P7250
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.
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.

36. When plugging in two or more radios within the same radio band (i. e
When plugging in two or more radios within the same radio band (i.e. FAMS VHF radios) into a radio bridge, you must 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. Use external antennas with 25’ cables connected to the radios (Sti-CoTM model MGNT-FT-NITI, you will need to have the antenna tuned to the frequency of the radio).

37. Don’t use “SCAN” mode for any radios connected to a radio bridge
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 "ping-pong", interfering with the function of the bridge.
