1 INTRODUCTION1.1 What is Digital Selective Calling?Digital Selective Calling or DSC is the globally adoptedgeneral purpose system for selective calling in ship-toship,ship-to-shore and shore-to-ship directions. Thesystem is used on both MF/HF and VHF frequencies.The Global Maritime Distress and Safety System, orGMDSS, requires the use of DSC for distress alertingand safety calls.For everyday use, DSC is a reliable and easy way toestablish contact between two maritime mobile parties,and can be best compared to ordinary telephony.DSC is based on modern digital communicationtechniques and has many advantages and possibilitiescompared to the currently known call procedures inmaritime radiocommunication.One of the system’s advantages is that calls to and fromthe ship are automatically received by the other party,and an audible alarm announces to the operator that acall has been received. The contact is hereby fast andreliably established.1.1.1 The Digital Selective CallingsystemThe DSC system is used for both distress and safetycommunication as well as everyday communication.The system makes it possible to make direct calls fromship-to-ship, ship-to-coast station and coast station-toship.The calls contain information about the reason for thecall (distress, urgency, safety or ordinary call) andinformation about the channel where the subsequentinformation is to continue. A typical composition of aDSC calling sequence is:Signal:Method of composition:- format specifier selected- address entered- category selected- self-identification pre-programmed- telecommand information selected- frequency information entered- telephone number entered- end of sequence signal selectedThe format specifier specifies to whom the call isaddressed e.g. if it is an individual or an all ships call.The address is used in individual calls to specify whichship is to receive the call.The category is used to specify the call priority, e.g. if itis a safety related or an ordinary call.The self-identification is your own MID-number which isstored in the DSC unit.The telecommand information is used to specify e.g.the type of following communication i.e. simplex orduplex.If you want to speak to the other party you can enter thefrequency information in terms of a proposed workchannel number.Where the coast stations implement automatic services,DSC gives you direct access to the national telephonenetwork (dial-trough). This is done by entering atelephone number in the call.The end of sequence signal is used to specify to thecalled party if you want an acknowledgment of the call,if no acknowledgment is wanted or if the call is anacknowledgment of a received call.The information in the call is transmitted by usingcharacters composed from a ten-bit error-detectingcode. The characters are transmitted twice in a timespreadmode which increases the possibility of correctreception under poor conditions.1.1.2 Equipment classesThree equipment classes for DSC equipment aredefined:Class A: Intended to meet the IMO GMDSS carriagerequirements. Includes all facilities of CCIR Rec. 493-4, e.g. all call types with all possible combinations ofcategories and telecommands and additionalinformation blocks.Class B: Limited number of calls which providesalerting, acknowledgments and relay facilities fordistress purposes, calling and acknowledgment forgeneral communication purposes and calling inconnection with semi-automatic/automatic services.Class C: Equipment intended as add-on for VHFequipment to provide DSC alerting giving shipidentification only.1.2 Your S.P. Radio VHF DSC receivermodemThe following gives a short introduction to your S. P.Radio VHF receiver modem and its features. For amore technical description please, refer to the technicalmanual for this product.1.2.1 Technical specificationsYour S.P. Radio VHF DSC receiver modem complieswith the international requirements stated by IMO in theGlobal Maritime Distress and Safety System, known asGMDSS.The VHF DSC receiver modem allows you to encodeand decode all the messages applicable for VHF ClassA Digital Selective Calling equipment as defined inCCIR Rec. 493-4 and Rec. 689.The method of operation complies with the operationalprocedures for use of digital selective calling equipmentas defined in CCIR Rec. 541-3.RM2042 - INTRODUCTION 1-1

1.2.2 InterfacesFor use with S. P. Radio VHF transceivers (simplex aswell as duplex), the DSC is equipped with a serialinterface which allows for fully automatic DSC operation.This interface also works with the S. P. Radio scrambleroption.For VHF’s without serial interface, the DSC has a 600ohms balanced output plus key information for use withindependent VHF units where the DSC works as anencoder.A serial interface to navigational equipment, thatconforms to the NMEA 0183 standard, is also standard.For ships where the DSC unit is not located near thesteering wheel, an S. P. Radio remote alarm box can beconnected for remote control of distress calls andindication of received distress and urgency messages.The DSC unit can furthermore be connected to aCentronics compatible line printer.1.2.3 Call compositionSince the DSC protocol specifies a great variety ofcalls, the composition of the calls can be fairly complex.To ease the daily use of DSC and in order to simplify thecomposition of calls, your DSC is equipped with a menuoperated user interface.The calls are easily composed because of the menuoperated user interface that guides you trough the callcomposition. Likewise, the functions of the controls andtheir location are designed for quick and efficientoperation, minimizing the risk of inadvertent activation.The encoding of calls is divided into ‘simple calls’ and‘complete calls’. The simple calls need only a limitedamount of information to be transmitted. This is donebecause most calls will be simple ship/ship or ship/shore calls where one party calls another telling that hewould like to talk on a specific working channel.The individual selective ship/ship and ship/shore callscan be best compared to ordinary telephone callswhere you dial a number and wait for the called party toanswer.The complete calls contain more specific informationthat has to be entered before the calls can be transmitted.A call of this type could e.g. be to ships in a specificgeographical area.number for each station, you can use the alphabeticalsearch function and find the name of the wanted stationand use that in the call composition. The station registercan contain up to 100 stations.Real-time clock.Channel 70 is used for digital selective calling on VHF.To ensure continuous watch on channel 70, the VHFDSC receiver modem has a separate channel 70receiver.If a GPS or another type of navigational equipment isconnected, the ship’s position will automatically beinserted in a distress call.Used with an S.P. Radio simplex or duplex VHFtransceiver, the VHF DSC gives you a fully automatedsystem, allowing you to send automaticacknowledgments of calls and giving you access to thecoast stations’ automatic services.Your VHF DSC also supports the Automatic TransmitterIdentification Service (ATIS) used in the Rhineradiotelephone service. A connected S. P. Radio VHFtransceiver can ask the DSC to transmit an ATIS calleach time the handset key is released, or when thehandset key has been pressed for more than 5 minutes.The received calls can be printed as they arrive if aCentronics compatible printer is connected.1.3 About the manualThis manual describes the use of the VHF DSC receivermodem. The manual is divided into three major parts‘OPERATION’, ‘SET-UP’ and ‘CALLS’.The principles and facilities of the user interface aredescribed in Chapter 3: ‘OPERATION’.Details about how to set-up the various functions andfeatures of the VHF DSC are described in Chapter 4:‘SET-UP’.It is recommended to first read the Chapter‘OPERATION’ to understand the basic use of the VHFDSC. It is then an easy task to transmit calls usingChapters 5 to 11 as reference.The chapters 12 and 13 describe the use of the addressbook and station register.1.2.4 FeaturesYour VHF DSC includes a number of features thatmakes the everyday use of DSC easier.It is fx. possible to store frequently used calls in the builtinaddress book. The calls can be stored under a namethat refers the call to a ship or company. A specific callis easily found by using the alphabetical search functionwhich makes it simple to find and transmit the storedcalls. The address book can contain up to 40 calls.It is also possible to store a list of your most frequentlyused stations with their names and numbers, coaststations as well as mobile stations, in the built-in stationregister. This means that instead of remembering the1-2 RM2042 - INTRODUCTION

2 CONTROLSWhen designing the controls for your VHF DSC, wehave used the company’s extensive knowledge/experience in manufacturing maritime communicationequipment to ensure that the location and the functionsof the controls are designed for quick and efficientoperation. This ensures that your everyday use of theequipment becomes as easy as possible.2.1 Design philosophyThe philosophy behind the design of the front plate hasbeen to keep the most vital and most used information/features on the front plate in shape of keyboard keys.This gives an easy access to the equipment’s mainfunctions.2.1.1 The keyboardThe design and placement of the keys has been donewith the intent of placing keys that belong together, i.e.have related functions, into logically connected groups.When you look at the front plate, you will note that thekeys that select e.g. the main menus are placed in onegroup, the keys that are used to move around in themenues are placed in another and the keys used foralphanumerical input are placed in a third group.The keys are placed in a manner that minimizes the riskof inadvertent activation of distress calls.2.1.2 The displayIn order to make the operation of the equipment as easyas possible, your VHF DSC is equipped with a fullyalphanumeric LCD-display.This makes it possible to use a menu guided userinterface, making it an easy task to compose all kindsof calls, since the read-out in the menus is in plainlanguage.On/OFF andVOLume controlFlashing text shows that The flashing cursor Symbols indicatingthis is one of more possibillitieswhich can be selectedindicates where analphanumerical inputwill occurthat the up and downarrow keys can be usedto change the flashing textRemote controlof connectedS.P.
