47、e minimum requirements for equipment to be used for generation, transmission and reception of Digital Selective Calling (DSC) for use on board ships. DSC may be used in the Medium Frequency (MF), High Frequency (HF) and Very High Frequency (VHF) Maritime Mobile Service (MMS), both in connection with

48、 distress and safety communication and in connection with public correspondence. The present document covers the requirements to be fulfilled by: - - DSC equipment integrated with a transmitter and/or a receiver; DSC equipment not integrated with a transmitter and/or a receiver. These requirements i

49、nclude the relevant provisions of the Radio Regulations 5 and lTU-R Recommendations, the International Convention for the Safety Of Life At Sea (SOLAS) 3, and the relevant resolutions of the International Maritime Organization (IMO). Equipment for generation, transmission and reception of DSC is recommended to be designed according to following equipment classes: - - Class A - includes all the facilities defined in annex 1 of iTU-R Recommendation M.493-6 6; Class B - provides minimum facilities for equipment on ships not required to use class A equipment and c
