Global Maritime Distress Safety System - Wikipedia, the free encyclopedia
. High Frequency The GMDSS includes (HF) radiotelephone and (narrow-band direct printing) equipment, with calls initiated by digital selective calling (DSC).. Digital Selective Calling The IMO also introduced (DSC) on MF, HF and as part of the GMDSS system.. DSC was intended to eliminate the need for persons on a ship's bridge or on shore to continuously guard radio receivers on voice radio channels, including VHF channel 16 (156.8 MHz) and now used for distress, safety and calling.. VHF digital selective calling also has other capabilities beyond those required for the GMDSS.. Sea Area A1 An area within the radiotelephone coverage of at least one VHF coast station in which continuous digital selective calling (ch70) alerting and radiotelephony services are available, as defined by the International Maritime Organization.. Morse encoded distress calling has saved thousands of lives since its inception almost a century ago, but its use requires skilled radio operators spending many hours listening to the radio distress frequency.

Digital Selective Calling
Digital Selective Calling Purpose of DSC Digital Selective Calling provides automated access to coast stations and ships.. DSC Call Format All DSC calls automatically include phasing signals, error-checking signals and the identity (MMSI number) of the calling station.. These frequencies are programmed into the DSC equipment for selection when necessary; also in each band there are both national and international call and reply frequencies for routine calling.. On the band, channel 70 is used for distress/safety as well as routine calling.. General Calling Procedures Routine calls should be made just once on a single frequency or channel.. If the call is still not acknowledged, the coast station should normally wait at least another 30 minutes before repeating the call attempt on the same frequency, or 5 minutes on another calling frequency.. If no channel is mentioned, as would normally be the case when calling a coast station, suitable frequencies or channels should be proposed in the acknowledgement.

Initially a partial answer was found by shifting some of the calling traffic off channel 16.. The name, Digital Selective Calling, goes a long way to explaining how it works.. It is used for calling another station to advise them that there is traffic for them, and to what channel or frequency they should tune their radio to receive this traffic.
