Title 47 - Telecommunication
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_locations.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 §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 §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 §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.
