Attachment A - Joint Agreement for 800 MHz CCCS Page 57 of 83 The Lead Agency will work with each user agency to develop the subscriber templates for that agency. All subscriber template creation and modification shall be done by the Lead Agency. The Lead Agency shall maintain all associated documentation for each subscriber template. Procedure If individual agencies desire to make updates and/or changes to their subscriber templates, those change requests shall be submitted to the Lead Agency for review. The Lead Agency will approve or deny the request after reviewing impact to the System and other users. If approved, the costs for template change and subsequent reprogramming of subscriber radios will be borne by the requesting agency. The disclosure of the subscriber template configuration information, including talkgroup IDs, user IDs, user privileges and other related System information could substantially jeopardize the security of the System. This disclosure makes it more susceptible to tampering, sabotage, unauthorized use, jamming, hacking, unauthorized access to the contents of confidential voice and data communications. Therefore, the subscriber template spreadsheets shall be classified as 'Restricted Information' and are not available to the general public except by formal written request to the 800 MHz CCCS Governance Committee. Management The Lead Agency manages all subscriber templates and programming for all agencies and maintains records of the process. Access is strictly controlled and is considered 'Restricted Information'. 5.5 Talkgroup Assignments Purpose or Objective Defines the assignment/usage of agency -specific, common and interoperable/mutual aid talkgroups and resources, and provides a standard so that the Lead Agency will have a firm guideline on allowing particular talkgroups programmed into radios. Operational Context Talkgroups are considered assigned by the agency for which the talkgroup was specifically created. The process for pre -defined sharing authorizations is explained in Section 5.6. Recommended Protocol/Standard There are three types of talkgroups that are programmed into the System: Agency -Specific — Created for, and controlled by, individual agencies for their day-to- day operations. These talkgroups cannot be accessed by other System users without express permission granted by the assigned agency. The process for obtaining this permission is outlined in Section 5.6. Common Resources —Talkgroups/channels created for common use among discipline specific agencies (law, fire, general) as needed. These talkgroups/channels are not controlled by any individual agency but are available for use by all Partner Agencies and are coordinated by the Control One.
