ISPERN Illinois State Police Emergency Radio Network
ISPERN (NIP VLAW31)* A N 155.475 CSQ/D156 155.475 D156 State and Local Interop Law Enforcement
- The channel has the same frequency as the non-federal Nation Interoperable Pool (NIP) channel but with an Illinois specific PL tone instead of the NIP PL Code of 156.7
- CTCSS Tones – Default operation should be carrier squelch receive (CSQ), CTCSS Transmit. If the user can enable/disable without programming the radio, the indicated CTCSS tone also
could be programmed for receive, and the user instructed how and when to enable/disable.
- ISPERN equipped radios must be operated only by law enforcement personnel.
- Routine communications on the ISPERN frequency between units owned by the same political subdivision is not permitted.
- Power output must not exceed 132 effective radiated power (ERP) for Mobile or base
- Provides personnel in police mobile units with an inter-agency communication capability for police activity of an emergency nature within the State of Illinois.
- Operates on a radio frequency assigned to the Illinois State Police by the Federal Communications Commission.
- Is under the control of the Director of the Illinois State Police.
- To accomplish the objectives of ISPERN, specific criteria for allowable communications have been established. The following eight types of communications are listed in priority ranking:
- Emergency
- Disaster
- Pursuits
- Criminal/traffic offense or missing persons
- Hit alerts
- Mobile-to-mobile coordination
- Itinerant
- Testing
- Mobile Command Post Eligibility Requirements.
- The ISPERN frequency may only be installed in Mobile Command Posts (Emergency Communications Vans) with the prior approval of the ISPERN Governing Board, and by meeting the following guidelines:
- ISPERN is a law enforcement frequency, therefore, use of the ISPERN frequency in the Communications Van/Mobile Command Post must be under the control of a police agency.
- Antenna height and effective radiated power (ERP) must be limited to that necessary to communicate with vehicle installed radios in the area of the emergency. Care must be taken to prevent interference with ISPERN traffic in adjacent areas.
- The local ISPERN Control Point will remain the network control station and shall coordinate traffic on this frequency to minimize interference. The Communications Van/Mobile Command Post shall notify the ISPERN Control Point when a drill begins and request that they broadcast a dispatch on ISPERN announcing the drill. When a drill is concluded, the Control Point shall be notified and a dispatch made advising the conclusion of the drill.
- ISPERN and FCC rules and regulations shall be followed.
- The use of ISPERN by the Communications Van/Mobile Command Post for test or drills shall not interfere with legitimate emergency traffic. Drill traffic shall cease until such emergency traffic clears.
- Disaster drill traffic shall not include false or misleading messages, but will consist primarily of inter-agency coordination of mobile units.

General Communications Rules of Use
Purpose - The purpose of the document is to provide general information about the State of Illinois Public Safety Interoperable channels.
NIMS/ICS/Plain Language/Unit Identification
- National Incident Management System – Use of an Incident Command System compliant with the National Incident Management System is recommended for use of any regional interoperability resource, i.e. implementing a Communications Unit Leader position.
- It is the responsibility of the Incident Commander/designee to establish the tactical callsigns to be used for the incident. It is the responsibility of all users to refer to facilities and staff by the proper tactical callsigns.
- Plain language – All communications shall be in plain language. Radio codes, acronyms and abbreviations are to be avoided as they may cause confusion between agencies. The reason for a request for assistance or backup should be clearly stated.
- Unit Identification – Agency name followed by identifier or resource type (i.e., IEMA 12, Fire Marshal David Adam 1, Secretary of State Police – Car 3 John 40, etc.).
Calling Another Unit
- A user should call another user using the – “called unit from calling unit” format (also known as the “hey you –it’s me” format) using unit identifiers as shown in 3.1.1 (above) as in: “Illinois State Police Car 2-5 from IEMA 3” ....... Followed by: “IEMA 3 from Illinois State Police Car 2-5, go ahead”
Important
- NOTE: State level interoperable channels (ISPERN, IFERN, POINT, IREACH, ESMARN, and MABAS firegrounds) are used on a daily basis for day-to-day interoperable communications. Using these channel resources could affect ongoing operations in a nearby community. Please clarify/assess the need for the resource as an interoperable resource and be sensitive to how the state interoperable resources are used in a particular area.
- NOTE: Scanning across multiple channels is generally not advised when using interoperable communications.
- NOTE: Encryption shall not be used at any time on any simplex, State or National interoperable channel, including ISPERN, IREACH, IFERN, MERCI.

(Future) Metro East Regional Headquarters
- 9/22 - HQ will move to East St Louis New Link
- New $55 million, 62,000-square-foot facility with a 21,000-square-foot warehouse; should be completed around 2026-2027
- Planning, site acquisition, and construction of a new facility to accommodate in excess of 180 ISP personnel and include the following ISP work units: Troop 8 (D11) Patrol Headquarters, Communications Service Bureau, Zone 6 Investigations, Division of Internal Investigations, Illinois Gaming Board, Medicaid Fraud Control Bureau, and South SWAT. All of these work units currently are located in the Regional State building in Collinsville (shared with IDOT), with the exception of South SWAT. The Regional State building work units occupy approximately 50,000 square feet of space. In addition to this space, South SWAT would require approximately 2,500 square feet of office space and 12,500 square feet of storage space. Relocating South SWAT to the Metro-East area in a new facility would provide adequate storage for specialty equipment and would provide for better response times in an area of the state with a growing significance for SWAT services. Relocating investigations and patrol will also have force-multiplying effects in reducing violent crime and improving traffic safety enforcement in high-crime, low-resource areas that are increasingly reliant upon the ISP for public safety services. This new facility should include a new firing range and training room which is critical to maintaining standards and improving safety outcomes in high risk situations. A combined facility would also enhance operational efficiencies for these work units. Finally, construction of a new facility will allow the
ISP to combine several work locations reducing yearly repair and maintenance costs and eliminate the need to lease specialty space for SWAT.

Ideally, as staffing increases and the ability to staff COMPAT in the Metro-East footprint on closer to a 24/7 basis, the community will become familiar with the professional ISP officers and increased community trust will occur.

IREACH A N 155.055 Receive CSQ/D156*; 155.055 D156 Inter-agency All
- CTCSS Tones – Default operation should be carrier squelch receive (CSQ), CTCSS Transmit. If the user can enable/disable without programming the radio, the indicated CTCSS tone also could be programmed for receive, and the user instructed how and when to enable/disable. Used for interdisciplinary coordination.
The purpose of IREACH is to allow any public safety employee to talk to any other public safety employee via radio provided the radio traffic relates to their official duties and the protection of life and/or property. For example, to permit a firefighter to have direct radio contact with an EMT in an ambulance or to enable a police officer to talk to an EMA/ESDA official at a disaster site.
