  • 2-4-12. INTERPHONE MESSAGE FORMAT

    Use the following format for interphone intra/interfacility communications:

    1. Both the caller and receiver identify their facility and/or position in a manner that ensures they will not be confused with another position.

      NOTE: Other means of identifying a position, such as substituting departure or arrival gate/fix names for position identification, may be used. However, it must be operationally beneficial, and the procedure fully covered in a letter of agreement or a facility directive, as appropriate.

      • EXAMPLE
      • Caller: “Albuquerque Center Sixty Three, Amarillo Departure.”
      • Receiver: “Albuquerque Center.”
    2. Between two facilities which utilize numeric position identification, the caller must identify both facility and position.
      • EXAMPLE
      • Caller: “Albuquerque Sixty Three, Fort Worth Eighty Two.”
    3. Caller states the type of coordination to be accomplished when advantageous. For example, handoff or APREQ.
    4. The caller states the message.
    5. The receiver states the response to the caller’s message followed by the receiver’s operating initials.
    6. The caller states his or her operating initials.
      • EXAMPLE
        • 1. Caller: “Denver High, R Twenty-five.”
        • Receiver: “Denver High.”
