1 INTRODUCTION1.1 What is Digital Selective Calling?Digital Selective Calling (DSC) is a globally adoptedgeneral purpose system for selective calling in the shipto-ship,ship-to-shore and shore-to-ship directions. Thesystem is used on both MF/HF and VHF frequencies.Digital Selective Calling (DSC) can be used for distressalerting and safety calls and is a major building block inthe Globa Maritime Distress and Safety System(GMDSS).Digital Selective Calling (DSC) can be used to automaticset up a public call when a telephony or telexcommunication is wanted with an other mobile unit ora coast station.1.3 About the ManualThis manual describes the use of the MF/HF DSCreceiver modem RM2150/RM2151.The MF/HF DSC is easy to use because of its menuguideduser interface. The principles and facilities ofthe user interface are described in Chapter 3 under theheadline “Operation”.We recommend that you start by reading Chapter 3,“Operation” in order to understand the basic use of theMF/HF DSC. Transmission of calls using this manualas reference will then be an easy task.Digital Selective Calling (DSC) can give direct accessto the national telephone network when this services isimplemented at the coast station.1.2 Your MF/HF DSC Receiver ModemYour MF/HF DSC receiver modem RM2150/RM2151complies with the international requirements listed byIMO in the Global Maritime Distress and Safety Systemalso known as GMDSS.The MF/HF DSC receiver modem RM2150/RM2151allows you to encode and decode all the messagesapplicable for MF/HF equipment for Digital SelectiveCalling.Combined with an HF SSB transceiver and telex, theMF/HF DSC gives you a fully automated system withthe option of transmitting automatic acknowledgementsof calls as well as access to the automatic services ofthe coast stations.On the HF band a different pair of frequencies is usedfor digital selective calling for both distress calls andordinary calls. The DSC modem can scan up to 10frequencies thereby ensuring a continuous watch overships or coast stations.The result is that you are able to transmit and receivedistress calls as well as selective ship-to-ship or shipto-shorecalls.In distress situations, distress calls with indication of thevessel’s position can be easily initiated by pressing twobuttons only. The distress call is sent to all stations andautomatic re-transmissions of the distress call will continueuntil you receive a distress acknowledgement call.The individual selective ship-to-ship and ship-to-shorecalls can be compared to ordinary telephone calls. Youdial a number and wait for the other party to reply. Whena reply is received, the DSC modem will automaticallyset up the communication frequencies and mode.The encoding of calls is divided into simple and completecalls. Simple calls need a limited amount ofinformation in order to be transmitted. This is so becausemost calls will be simple ship-to-ship and shipto-shorecalls where a party calls another party statingthat he would like to talk on a specific working channel.RM2150/RM2151 - INTRODUCTION 1-1

7 STANDARD CALLThe system holds two options for public call: “Standard call”and “ Extended call”.The “Standard call” has been developed in order to facilitatethe calls, however it does contain some limitations as many ofthe parameters are selected by default.A “Standard call” can only be used for ordinary calls where theformat specifier is “Individual Stations” (coast or ship stations)and the first telecommand is J3E ( telephony as communicationmode). The only parameter available will be informationon “Work on frequencies” and your position.7.1 Call without Position and WorkFrequenciesIf you make a “Standard call” without indication of position and“Work on frequencies”, the call will be transmitted withoutautomatic acknowledgement (EOS=117). The result is thatyou will not receive an automatic acknowledgement from thecalled station, but your modem will still listen at the callfrequency in five minutes in case the called station transmitsan acknowledgement manually.In order to make a “Standard call” without position and “Workon frequency”, start by pressing CALL. The display will showthe top of the call menu and prompt you for station name orstation “MID” number.Press CALLIn order to use the pre-programmed stations, the displayshould show “Call stn:” in the first line. If “Call MID”: is shown,use the left arrow key until “MID” flashes. You the up / downarrow keys to select between “MID” and “stn”. When “stn”flashes, enter the initial of the station name and the display willshow the first name in the table with this initial. Use the up /down arrow keys to select the name requested.If the station’s name is not pre-programmed, use the “MID”number of the station. In this case, the display should read“Call MID:” in the first line. If the display reads “Call stn:”, pressthe left arrow key until “STN” flashes. Use the up / down arrowkeys to select between “stn” and “MID”. When “MID” flashes,enter the nine-digit “MID” number of the station to be called.PressorJKL4JKL4JKL4Press 0 0DEF2 ABC 1YZ-9 ABC 1 0 0 0Having selected the station name or entered the station’s“MID” number, press ENT.
