The definitions of terms used in part 11 are:

(a) National Emergency Message (EAN). The National Emergency Message (formerly called the Emergency Action Notification or Presidential alert message) is the notice to all EAS Participants and to the general public that the EAS has been activated for a national emergency. EAN messages that are formatted in the EAS Protocol (specified in § 11.31) are sent from a government origination point to broadcast stations and other entities participating in the National Public Warning System, and are subsequently disseminated via EAS Participants. Dissemination arrangements for EAN messages that are formatted in the EAS Protocol (specified in § 11.31) at the State and local levels are specified in the State and Local Area plans (defined at § 11.21). A national activation of the EAS for a Presidential National Emergency Message with the Event code EAN as specified in § 11.31 must take priority over any other message and preempt it if it is in progress.

(b) EAS Participants. Entities required under the Commission's rules to comply with EAS rules, e.g., analog radio and television stations, and wired and wireless cable television systems, DBS, DTV, SDARS, digital cable and DAB, and wireline video systems.

(c) Wireline Video System. The system of a wireline common carrier used to provide video programming service.

(d) Intermediary Device. An intermediary device is a stand-alone device that carries out the functions of monitoring for, receiving and/or acquiring, and decoding EAS messages formatted in the Common Alerting Protocol (CAP) in accordance with § 11.56, and converting such messages into a format that can be inputted into a separate EAS decoder, EAS encoder, or unit combining such decoder and encoder functions, so that the EAS message outputted by such separate EAS decoder, EAS encoder, or unit combining such decoder and encoder functions, and all other functions attendant to processing such EAS message, comply with the requirements in this part.
