Sec.  80.225   Requirements for selective calling equipment.

   This section specifies the requirements for voluntary digital selective
   calling (DSC) equipment and selective calling equipment installed in ship
   and coast stations, and incorporates by reference ITU-R Recommendation
   M.476–5, “Direct-Printing Telegraph Equipment in the Maritime Mobile
   Service,” with Annex, 1995; ITU-R Recommendation M.493–10, “Digital
   Selective-calling System for Use in the Maritime Mobile Service,” with
   Annexes 1 and 2, 2000; ITU-R Recommendation M.625–3, “Direct-Printing
   Telegraph Equipment Employing Automatic Identification in the Maritime
   Mobile Service,” with Annex, 1995; and RTCM Paper 56–95/SC101–STD, “RTCM
   Recommended Minimum Standards for Digital Selective Calling (DSC) Equipment
   Providing Minimum Distress and Safety Capability,” Version 1.0, dated August
   10, 1995. ITU-R Recommendations M.476–5 with Annex, M.493–10 with Annexes 1
   and 2, and M.625–3 with Annex, and RTCM Paper 56–95/SC101–STD are
   incorporated by reference. The Director of the Federal Register approves
   this incorporation by reference in accordance with 5 U.S.C. 552(a) and 1 CFR
   Part 51. Copies of these standards can be inspected at the Federal
   Communications Commission, 445 12th Street, SW., Washington, DC (Reference
   Information Center) or at the National Archives and Records Administration
   (NARA). For information on the availability of this material at NARA, call
   202–741–6030, or go to:
   http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_loc
   ations.html. The ITU-R Recommendations can be purchased from the
   International Telecommunication Union (ITU), Place des Nations, CH–1211
   Geneva 20, Switzerland. The RTCM standards can be purchased from the Radio
   Technical Commission for Maritime Services (RTCM), Suite 600, 1800 Diagonal
   Road, Alexandria, Virginia 22314–2480.

   (a) DSC equipment voluntarily installed in coast or ship stations must meet
   either the requirements of ITU-R Recommendation M.493–10, “Digital
   Selective-calling System for Use in the Maritime Mobile Service,” with
   Annexes 1 and 2, 2000 (including only equipment classes A, B, D, and E) or
   RTCM Paper 56–95/SC101–STD. DSC equipment must not be used with the sensors
   referred to in  Sec. 80.179(e)(2). DSC equipment used on compulsorily fitted
   ships must meet the requirements contained in subpart W of this part for
   GMDSS.

   (b) Manufacturers of Class C DSC equipment to be used on United States
   vessels must affix a clearly discernible permanent plate or label visible
   from the operating controls containing the following:

   Warning. This equipment is designed to generate a digital maritime distress
   and safety signal to facilitate search and rescue. To be effective as a
   safety device, this equipment must be used only within communication range
   of a shore-based VHF marine channel 70 distress and safety watch system. The
   range of the signal may vary but under normal conditions should be
   approximately 20 nautical miles.

   (c) Selective calling equipment, other than that designed in accordance with
   paragraph (a) of this section, is authorized as follows:

   (1) Equipment used in conjunction with the Automated Maritime
   Telecommunications System (AMTS) in the band 216–220 MHz,

   (2) Equipment used to perform a selective calling function during
   narrow-band direct-printing (NB-DP) operations in accordance with ITU-R
   Recommendation M.476–5, “Direct-Printing Telegraph Equipment in the Maritime
   Mobile Service,” with Annex, 1995, or ITU-R Recommendation M.625–3,
   “Direct-Printing Telegraph Equipment Employing Automatic Identification in
   the Maritime Mobile Service,” with Annex, 1995, ITU-R Recommendation
   M.493–10, “Digital Selective-calling System for Use in the Maritime Mobile
   Service,” with Annexes 1 and 2, 2000, and

   (3) Equipment functioning under the provisions of  Sec. 80.207(a) includes the
   brief use of radiotelegraphy, including keying only the modulating audio
   frequency, tone signals, and other signalling devices to establish or
   maintain communications provided that:

   (i) These signalling techniques are not used on frequencies designated for
   general purpose digital selective calling (DSC) and distress and safety DSC
   calling as listed in  Sec. 80.359;

   (ii) The authorized radiotelephone emission bandwidth is not exceeded;

   (iii) Documentation of selective calling protocols must be available to the
   general public; and,

   (iv) Harmful interference is not caused to stations operating in accordance
   with the International Radio Regulations.
