Sec.  25.111   Additional information.

   (a)  The  Commission may request from any party at any time additional
   information concerning any application, or any other submission or pleading
   regarding an application, filed under this part.

   (b) Applicants, permittees and licensees of radio stations governed by this
   part shall provide the Commission with all information it requires for the
   Advance Publication, Coordination and Notification of frequency assignments
   pursuant  to  the  international Radio Regulations. No protection from
   interference caused by radio stations authorized by other Administrations is
   guaranteed unless coordination procedures are timely completed or, with
   respect  to  individual  administrations,  by  successfully completing
   coordination  agreements.  Any  radio  station authorization for which
   coordination has not been completed may be subject to additional terms and
   conditions as required to effect coordination of the frequency assignments
   with other Administrations.

   (c) In the Direct Broadcast Satellite service, applicants and licensees
   shall also provide the Commission with all information it requires in order
   to modify the Appendix 30 Broadcasting-Satellite Service (“BSS”) Plans and
   associated Appendix 30A feeder-link Plans, if the system uses technical
   characteristics differing from those specified in the Appendix 30 BSS Plans,
   the Appendix 30A feederlink Plans, Annex 5 to Appendix 30 or Annex 3 to
   Appendix 30A. For such systems, no protection from interference caused by
   radio stations authorized by other Administrations is guaranteed until the
   agreement of all affected Administrations is obtained and the frequency
   assignment becomes a part of the appropriate Region 2 BSS and feeder-link
   Plans. Authorizations for which coordination is not completed and/or for
   which the necessary agreements under Appendices 30 and 30A have not been
   obtained may be subject to additional terms and conditions as required to
   effect  coordination or obtain the agreement of other Administrations.
   Applicants  and  licensees  shall also provide the Commission with the
   necessary Appendix 4 information required by the ITU Radiocommunication
   Bureau to advance publish, coordinate and notify the frequencies to be used
   for tracking, telemetry and control functions of DBS systems.
