“Interoperability Resources” are groups of talkgroups available for users to communicate on the Statewide Radio System (SRS). To simplify the communication process for users, specific talkgroups are available for different needs and types of users. Statewide SRS interoperability resources are provided to all SRS users on their consoles and radios. System users are provided a complete standardized programming template (fleetmap) that organizes all these resources.
ROC – Regional Operations Common Talkgroups (See more information on the ROC tab)
ROC talkgroups are used for interoperability between SRS users and non-SRS users. State dispatch centers and local PSAPs monitor the ROC CALL talkgroup in their respective State Patrol dispatch region ("A" through "E", and "H"). ROC CALL is the hailing talk group used to initiate contact, then users should move to ROC 1 or ROC 2 to continue the conversation. See the list of the ROC Talkgroups for all regions.

EVNT – Event Talkgroups
EVNT talkgroups are available for statewide use by SRS user agencies for events (planned and unplanned) involving joint response from multiple SRS user agencies such as a major vehicle accident or snow storm. They are not encrypted. EVNT M7, EVNT M8, EVNT 9, and EVNT 10 are encrypted. All others are not. EVNT talkgroups M1 through M8 are monitored by State dispatch and EVNT talkgroups 9-16 are not monitored. State dispatch centers coordinate assignment of the 16 EVNT talkgroups for specific events and time periods. Users wanting to check out these talkgroups for their event can contact State dispatch by calling 308-535-8047 for North Platte, 402-331-3333 for Omaha, and 402-471-4680 for Lincoln Headquarters. State dispatch can also be contacted on ROC CALL for each region. See the list of EVNT talkgroups below.

LE – Law Enforcement Talkgroups
LE (Law Enforcement) talkgroups are another means of communication available only to law enforcement agencies that use the SRS as their primary radio communications system. They are regionalized by State Patrol troop areas and may be patched by dispatchers to other agency talk groups as necessary for joint response. LE 1 and x LE 2 are unencrypted. LE Secure 3 is for secure communication using AES encryption. See the list of all LE Talkgroups below.

Proprietary Talkgroups
All SRS users are entitled to their own agency specific talkgroups. A standardized fleetmap programming template (shown below) organizes each agency’s proprietary talkgroups with other local conventional channels and shared SRS talkgroups based on the agency’s eligibility and operational requirements. Law enforcement agencies also receive the LE talkgroups.
FLEET MAP SAMPLE
National Interoperability Frequencies:
The Federal Communications Commission (FCC) designated interoperability frequencies available nationwide to any FCC-licensed public safety agency. These are another resource that an SRS user may use to communicate with a non-SRS user who may be using UHF or 700/800 MHz instead of VHF. All state agency SRS users have the VTAC and 8TAC national interoperability frequencies in their radios. Local agencies are encouraged to include the appropriate VTAC, UTAC, 7TAC, and 8TAC frequencies applicable to their radios. Mutual aid channels may be designated in a local or regional plan to be used by multiple agencies for specific uses: fire, police, or emergency medical services. For additional information, please see the latest National Interoperability Field Operations Guide (NIFOG)

Interoperability Planning:
- Statewide Communication Interoperability Plan (SCIP) is a multi-jurisdictional statewide plan to enhance emergency communications. The state of Nebraska version is under development. Contact Dave Collett for more information.
- Tactical Interoperable Communications Plan (TICP) is designed to allow states to document interoperability assets in the area showing how they are shared and how to request, activate, or deactivate them. This state of Nebraska document is under development. Contact Dave Collett for more information.
- Communication Assets Survey and Mapping Tool (CASM) is used by public safety agencies to document their communication assets and related information like radio systems, mutual aid channels/talkgroups, gateways, radio caches, dispatch centers, and points of contact. Login credentials are required. Dave Collett is the Nebraska CASM administrator who can be contacted for further information.
