Attachment A - Joint Agreement for 800 MHz CCCS Page 62 of 83 In the event that the monitoring point is not the same agency as the radio user, an agreement on policy, monitoring, use, and response, shall be in place among the agencies. Established monitoring points shall be available during any/all hours that personnel are using the System, or have an established after-hours arrangement with another monitoring point. No dispatcher shall clear an emergency without ascertaining what action is necessary to handle said emergency and taking the appropriate actions to do so. Control One receives all emergency button activations and will contact originating radio user's agency for follow-up when activations occur on common/interoperable talkgroups that are not assigned specifically to the agency in question. Management The Lead Agency will manage the overall Emergency Button policy. Agencies desiring to use the emergency key function shall coordinate with agency resources that receive the emergency calls. The receiving agencies shall have an appropriate plan in place and documented as to the process to handle the emergency calls. 5.12 Encryption Purpose or Objective Establishes guidelines for the use of encryption on the System. Technical Background Encryption is an option on digital radio equipment that must be specially ordered and manually configured. System users may or may not be capable of encryption depending on their equipment configuration and operational needs. AES is the approved standard for encryption on the System. Operational Context The use of encryption in the System is strapped to the specific talkgroups determined by the System users to provide secure communications. Encryption is not a feature that can be enabled or defeated at the user level. Each talkgroup is pre -determined to be either encrypted or clear and is programmed as such in the subscriber template. Radios transmitting with encryption cannot be heard by non -encrypted radios. An encrypted talkgroup that is patched to a non -encrypted talkgroup or channel is no longer considered secure communications as the encrypted audio is decrypted when pushed over the patched non -encrypted talkgroup/channel. Likewise, audio fed to an internet streaming application will not be secure. Protocol/Standard Only the Lead Agency is authorized to program encryption into radios on the System.
