1. RADIOTELEX COMMUNICATION1.1 GeneralTelex subscribers can attest to radiotelex as a reliable and efficientmethod for sending and receiving teleprinter connections. Telexsubscribers, especially those who often use HF-band radio circuits,will also attest that the telex connection is subject to interferencefrom a variety of sources, including atmospherics, fading and noisedisturbance. This interference plays havoc with radio signals, resultingin the receiving of information different from the intendedinformation. Thus a means must be provided to prevent mutilationof radio signals by interference on HF-band radio.Radiotelex communication today owes its reliability and efficiencyto error detection and correction. The ITU-R defined both a constant-ratiocode for automatic error detection and requirements forthe error correction in Recommendation M.625-3.1.2 Code DescriptionThe DP-6 employs a 7-element synchronous code providing 2 7 =128 combinations. Among these 128 combinations, there are 35constant-ratio combinations having a ratio of 3 (Y) mark bits to 4(B) space bits. Thus ratio is used to test the validity of each receivedcharacter.Of the 35 combinations, 32 are used for the required alphanumericteleprinter signals. The remaining three 7-element codes are usedexclusively for operational purposes. These are:Idle Signal (ARQ Mode), Phasing Signal 1 (FEC Mode)Idle SignalRQ Signal (ARQ mode), Phasing Signal 2 (FEC Mode)Transmission rate is 100 bauds. If the 4B/3Y ratio is disturbed dueto interference, the output of the receiver is blocked to restrict themutilated character from passing on to the teleprinter.Frequency ShiftThe frequency shift is 85 Hz with a center frequency of 1700 Hz,as specified in ITU-R Recommendation M.625-3.Space Tone Frequency 1700+85 = 1785 HzMark Tone Frequency 1700-85 = 1615 Hz1-1

1.3 ARQ Mode (A-Mode)DescriptionThe ARQ (Automatic Re-transmission request, or Automatic Requestfor repetition) Mode allows private communications betweenany two stations using semi-duplex communication. Receptionconfirmation is done to assure that each character is received correctly.Since the two stations (automatically) exchange identities,this affords some degree of protection for confidential messages.Traffic Exchange SequenceIn the ARQ mode two stations communicate directly with one another.One station sends information and receives controls signals,while the other station receives information and sends confirmingcontrol signals. The first station is the ISS (Information SendingStation), and the second is the IRS (Information Receiving Station).These functions are interchangeable by a special control signal.The station which initiates the call is the Master Station (MS). TheMS initiates the call by sending the selective identity code of thecalled station, consisting of an RQ signal and two traffic informationsignals, listening between blocks.Example: Identity Code XQKMX RQ Q K M RQCalling Block 1 Calling Block 2Example: Identity Code PEARDBYP RQ E RQ A RCalling Block 1 Calling Block 2D B YCalling Block 3Figure 1-1 How identity code is transmittedThe Slave Station (SS) recognizes own identity code received andanswers it is ready by sending a control signal. The calling stationthen initiates normal traffic.The ISS sends information in blocks of three characters. Each characteris sent at the rate of 100 bauds, amounting to 70 ms for onecharacter or 210 ms for one character block. The block repetitioncycle is 450 ms, so there is 240 ms during each cycle that the ISS is1-2

not sending. This time is taken up by propagation time from theISS to the IRS, 70 ms for the IRS to send its service informationsignal, and the return trip back to the ISS.The IRS listens between blocks and sends a control signal (CS1 orCS2) to request either the next block, or retransmission of the lastblock in the case of error. Request for retransmission may be repeatedup to 32 times, until the completed block has been receivederror-free. After 32 times, the ISS automatically initiates a newcall.INFORMATION3 CharactersCONTROL SIGNAL1 Character70 ms70 ms210 ms450 msFigure 1-2 ARQ mode traffic exchange timingOnce an entire message is received (error-free), a station may switchits function from the IRS to the ISS by means of a control signal(CS3). This change is done by either the ISS by the sequence of "Figure shift + ? ", or by the IRS operator by activating the "OVER"control. Upon receipt of CS3, ISS answers with a block. Thisswitches the ISS into IRS. However, the original Master and Slavestations' status remains unchanged, since the Master Station alwayscontrols the radio circuit.Termination of CommunicationOnly the ISS may terminate the established circuit. It does this bysending three "idle signals ." The IRS and ISS exchange controlsignals, each reverting to standby after acknowledging each other’ scontrol signals. Then, the connection is cleared.1-3

1.4 FEC Mode (B-Mode)DescriptionThe FEC mode is for one-way, uninterrupted transmission of messages,for example, weather forecasts and emergency bulletins, tono one particular station or stations. The sending station is knownas the BSS (B-Mode Sending Station), the receiving station theBRS (B-Mode Receiving Station).This mode uses a simple forward-error correcting (FEC) techniqueof sending each character twice at a 280 ms interval. The first transmissionis termed DX (direct transmission), the second RX (repeatedtransmission).Message: " a b c d e f g h i j "First transmission: a b c d e f g h i jSecond transmission:a b c d e f g h i j280 msOutput code ex.:a b c a d b e c f d g e h f i g j h i jFigure 1-3 FEC mode transmission techniqueThe receiving station tests the DX and RX characters for adherenceto the 4-mark/3-space constant ratio, and prints onlyunmutilated DX or RX characters, or prints a space if both aremutilated.Another version of the FEC mode is the FEC-selective mode. Thismode uses a call code for selective calling to one or more stations.Only those stations with the correct code will receive the data correctly.Initiating a CallWhen a BSS initiates a broadcast call it transmits synchronizingsignals to align phasing of the BRS. Upon detection of this signalthe BRS’s are switched to the receiving condition and will remainin this condition until the completion of the message. If the mutilatedcharacter error rate exceeds a certain percentage, the BRSreverts to standby condition.Termination of CommunicationThe sending station sends three consecutive idle signals α immediatelyafter the last transmitted information signal in the DX position.1-4

7. MARITEX OPERATIONThis chapter provides an overview to the MARITEX system. Fordetailed information, consult your MARITEX Traffic Manual.7.1 What is MARITEX?MARITEX, an acronym meaning MARItime TEleX, is a worldwide,round-the-clock, fully automatic and computerized networkfor maritime radiotelex. The MARITEX system is operated jointlyby the Telecom Administrations of Denmark, Finland, Iceland,Norway, and Sweden. The system consists of the Central ComputerSystem in Gothenburg, Sweden, run with two high technologycomputers, and sub-stations in Scandinavia, Panama, Manila,and Argentina. The Central System does all the message switchingand co-ordinates the sub-station resources.INTERNATIONALTELEX NETWORKSTORE-AND-FORWARDDIRECTDIALINGREMOTE-CONTROLLEDRADIO CIRCUITSSUB-STATIONPANAMAPARTICIPATINGSHIPSMULTI-ADDRESSMARITEXCENTRALSYSTEMSUB-STATIONSCANDINAVIAINTERNATIONALTELEPHONENETWORKSEMI-FAXSYSTEMCONTROLSUB-STATIONMANILASUB-STATIONARGENTINAFigure 7-1 MARITEX system and services7-1

MARITEX ServicesMARITEX provides four main services to MARITEX subscribers:• Store-and-forward telex• Direct dialing• Multi address• Semi-faxNote: MARITEX provides both shore-to-ship and ship-to-shoreservices. This manual, however, describes only the ship-to-shorecommunication procedures.7.2 Preparations for TransmissionTo transmit a message in the MARITEX system, you will need toregister three items:• Answerback code• Scan groups• Station namesRegistering Answerback CodeMARITEX assigns a Telex number to all MARITEX subscribers.This number functions as an answerback code. An answerback codecontains the following:OOOOO SHIP XOOOOO: MARITEX-assigned five-digit Telex codeSHIP: Ship nameX: For shipboard station, normally X is entered.The procedure for registering answerback code is the same as whichappears on page 3-1. If an answerback code was registered beforethe commissioning of the MARITEX station a new answerbackcode must be entered.

Registering Scan GroupsThe Central System emits a free-signal to indicate a MARITEXradio channel is in idle condition and available for ship-to-shorecalls. The free-signal is detected and recognized by the shipboardequipment as a permission to start the transmission. Then, the shipboardoperator initiates a call.You can scan search for the free-signal automatically by registeringMARITEX radio channels in scan group(s). The procedure forregistering scan groups for MARITEX use is the same as that whichappears on page 3-7.1. Press function key [F5] to display the Station menu.2. Press the [3] key to select Scan Entry.
