What are the ROC’s?

The Regional Operations Common (ROC’s) are shared talkgroups for SRS users to communicate with non SRS users on the Statewide Radio System (SRS). All state and local county dispatch centers have the ability to communicate on the ROC’s. Any local, state, or federal public safety agency has the ability to communicate on the SRS using the ROC’s with authorized equipment. The ROC talkgroups are regionally based on State Patrol troop areas: A through E and H for headquarters. See the attached map of the troop areas.

What are the requirements?

Authorized equipment is required in order to receive the ROC talkgroups. This can be an SRS “consolette” radio or a compatible dispatch console. SRS mobile and portable radios can also have the ROC Talkgroups. See ROC equipment.

All dispatch centers are expected to monitor the ROC CALL talkgroups 24 hours-a-day/
7 days-a-week in the ROC region in which their center is physically located. ROC regions have the designated hailing talkgroup (ROC CALL) to alert other SRS users and dispatch centers in their ROC region of an incident or situational awareness. Users also have two tactical talkgroups (ROC 1 and ROC 2) so a dispatch center can contact a neighboring region’s dispatch center at any time. The location of the user’s dispatch center determines whether it will have one or more of the regional ROC’s. Each region has the ability to move radio traffic to the tactical ROC 1 or ROC 2 talkgroup while resolving an incident.

Example 1: A dispatch center located in region D will monitor D ROC CALL. After a hailing request is received, it is appropriate to announce “Moving radio traffic to D ROC 1” (or D ROC 2). Other dispatchers will know if they should also move to D ROC 1 or D ROC 2 to coordinate with the incident.

Example 2: A pursuit in your region is moving toward your neighboring E ROC Region. In this case, a dispatcher will switch to E ROC CALL to alert the adjacent E ROC Region. That dispatcher should communicate with other dispatchers to switch to E ROC 1 or E ROC 2 to coordinate with the incident. 

The Public Safety Communications team conducts a weekly roll call to all ROC-enabled dispatch centers to insure that all agency ROC equipment is in working order and the dispatchers are practiced in answering the ROC CALL talkgroups.

How do the ROC talkgroups improve interoperability?

ROC’s provide a common method for any dispatch center in the state to communicate on the SRS, regardless of their console technology. ROC talkgroups are common between all SRS users and all dispatch centers. Local dispatch centers can choose to patch their local channel to the ROC talkgroups.  State and local agencies use ROC routinely to communicate with various users across the state. There is NO requirement to replace any local systems.   

What is the fee for using the ROC Talkgroups?

There is no SRS fee charged to use the ROC talkgroups.  However, the user agency is responsible for purchasing approved equipment, installation fees, and maintenance.
