1. RADIOTELEX COMMUNICATION

1.1 General

Telex subscribers can attest to radiotelex as a reliable and efficient

method for sending and receiving teleprinter connections. Telex

subscribers, especially those who often use HF-band radio circuits,

will also attest that the telex connection is subject to interference

from a variety of sources, including atmospherics, fading and noise

disturbance. This interference plays havoc with radio signals, re-

sulting in the receiving of information different from the intended

information. Thus a means must be provided to prevent mutilation

of radio signals by interference on HF-band radio.

Radiotelex communication today owes its reliability and efficiency

to error detection and correction. The ITU-R defined both a con-

stant-ratio code for automatic error detection and requirements for

the error correction in Recommendation M.625-3.

1.2 Code Description

The DP-6 employs a 7-element synchronous code providing 2⁷=

128 combinations. Among these 128 combinations, there are 35

constant-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 re-

ceived character.

Of the 35 combinations, 32 are used for the required alphanumeric

teleprinter signals. The remaining three 7-element codes are used

exclusively for operational purposes. These are:

Idle Signal (ARQ Mode), Phasing Signal 1 (FEC Mode)

Idle Signal

RQ Signal (ARQ mode), Phasing Signal 2 (FEC Mode)

Transmission rate is 100 bauds. If the 4B/3Y ratio is disturbed due

to interference, the output of the receiver is blocked to restrict the

mutilated character from passing on to the teleprinter.

Frequency Shift

The 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 Hz

Mark Tone Frequency 1700-85 = 1615 Hz

1.3 ARQ Mode (A-Mode)

Description

The ARQ (Automatic Re-transmission request, or Automatic Re-

quest for repetition) Mode allows private communications between

any two stations using semi-duplex communication. Reception

confirmation is done to assure that each character is received cor-

rectly. Since the two stations (automatically) exchange identities,

this affords some degree of protection for confidential messages.

Traffic Exchange Sequence

In the ARQ mode two stations communicate directly with one an-

other. One station sends information and receives controls signals,

while the other station receives information and sends confirming

control signals. The first station is the ISS (Information Sending

Station), and the second is the IRS (Information Receiving Sta-

tion). These functions are interchangeable by a special control sig-

nal.

The station which initiates the call is the Master Station (MS). The

MS initiates the call by sending the selective identity code of the

called station, consisting of an RQ signal and two traffic informa-

tion signals, listening between blocks.

Example: Identity Code XQKM

Calling Block 1

Calling Block 2

Example: Identity Code PEARDBY

Calling Block 1

Calling Block 2

Calling Block 3

Figure 1-1 How identity code is transmitted

The Slave Station (SS) recognizes own identity code received and

answers it is ready by sending a control signal. The calling station

then initiates normal traffic.

The ISS sends information in blocks of three characters. Each char-

acter is sent at the rate of 100 bauds, amounting to 70 ms for one

character or 210 ms for one character block. The block repetition

cycle is 450 ms, so there is 240 ms during each cycle that the ISS is

not sending. This time is taken up by propagation time from the

ISS to the IRS, 70 ms for the IRS to send its service information

signal, and the return trip back to the ISS.

The IRS listens between blocks and sends a control signal (CS1 or

CS2) to request either the next block, or retransmission of the last

block in the case of error. Request for retransmission may be re-

peated up to 32 times, until the completed block has been received

error-free. After 32 times, the ISS automatically initiates a new

call.

Figure 1-2 ARQ mode traffic exchange timing

Once an entire message is received (error-free), a station may switch

its 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. This

switches the ISS into IRS. However, the original Master and Slave

stations' status remains unchanged, since the Master Station al-

ways controls the radio circuit.

Termination of Communication

Only the ISS may terminate the established circuit. It does this by

sending three "idle signals ." The IRS and ISS exchange control

signals, each reverting to standby after acknowledging each other’ s

control signals. Then, the connection is cleared.

1.4 FEC Mode (B-Mode)

Description

The FEC mode is for one-way, uninterrupted transmission of mes-

sages, for example, weather forecasts and emergency bulletins, to

no one particular station or stations. The sending station is known

as the BSS (B-Mode Sending Station), the receiving station the

BRS (B-Mode Receiving Station).

This mode uses a simple forward-error correcting (FEC) technique

of sending each character twice at a 280 ms interval. The first trans-

mission is termed DX (direct transmission), the second RX (re-

peated transmission).

Message: " a b c d e f g h i j "

First transmission:

Second transmission:

a b c d e f g h i j

280 ms

Output code ex.:

a b c a d b e c f d g e h f i g j h i j

Figure 1-3 FEC mode transmission technique

The receiving station tests the DX and RX characters for adher-

ence to the 4-mark/3-space constant ratio, and prints only

unmutilated DX or RX characters, or prints a space if both are

mutilated.

Another version of the FEC mode is the FEC-selective mode. This

mode uses a call code for selective calling to one or more stations.

Only those stations with the correct code will receive the data cor-

rectly.

Initiating a Call

When a BSS initiates a broadcast call it transmits synchronizing

signals to align phasing of the BRS. Upon detection of this signal

the BRS’s are switched to the receiving condition and will remain

in this condition until the completion of the message. If the muti-

lated character error rate exceeds a certain percentage, the BRS

reverts to standby condition.

Termination of Communication

The sending station sends three consecutive idle signals α imme-

diately after the last transmitted information signal in the DX posi-

tion.

3.4 Scan Channel Groups

The DP-6 can automatically control radio equipment through chan-

nel scanning. The radio equipment scans a number of channels

(according to your selection), stopping when your own ID code is

detected in an incoming signal. The transmitter is tuned to the cor-

responding transmitter frequency, the communication link is es-

tablished and the traffic is automatically exchanged. Scanning

resumes once the link is disconnected.

You may store a maximum of 10 scan groups, 20 channels per

group. Note that scanning is only possible in the ARQ and FEC

modes.

7. MARITEX OPERATION

This chapter provides an overview to the MARITEX system. For

detailed information, consult your MARITEX Traffic Manual.

7.1 What is MARITEX?

MARITEX, an acronym meaning MARItime TEleX, is a world-

wide, round-the-clock, fully automatic and computerized network

for maritime radiotelex. The MARITEX system is operated jointly

by the Telecom Administrations of Denmark, Finland, Iceland,

Norway, and Sweden. The system consists of the Central Com-

puter System in Gothenburg, Sweden, run with two high technol-

ogy computers, and sub-stations in Scandinavia, Panama, Manila,

andArgentina. The Central System does all the message switching

and co-ordinates the sub-station resources.

MARITEX Services

MARITEX provides four main services to MARITEX subscrib-

ers:

• Store-and-forward telex

• Direct dialing

• Multi address

• Semi-fax

Note: MARITEX provides both shore-to-ship and ship-to-shore

services. This manual, however, describes only the ship-to-shore

communication procedures.

7.2 Preparations for Transmission

To transmit a message in the MARITEX system, you will need to

• Answerback code

• Scan groups

• Station names

Registering Answerback Code

MARITEX assigns a Telex number to all MARITEX subscribers.

This number functions as an answerback code.An answerback code

contains the following:

OOOOO SHIP X

OOOOO: MARITEX-assigned five-digit Telex code

SHIP:

Ship name

For shipboard station, normally X is entered.

The procedure for registering answerback code is the same as which

appears on page 3-1. If an answerback code was registered before

the commissioning of the MARITEX station a new answerback

code must be entered. To enter new answerback code, contact

FURUNO or authorized FURUNO agent or dealer.

Registering Scan Groups

The Central System emits a free-signal to indicate a MARITEX

radio channel is in idle condition and available for ship-to-shore

calls. The free-signal is detected and recognized by the shipboard

equipment as a permission to start the transmission. Then, the ship-

board operator initiates a call.

You can scan search for the free-signal automatically by register-

ing MARITEX radio channels in scan group(s). The procedure for

registering scan groups for MARITEX use is the same as that which

appears on page 3-7.

1. Press function key [F5] to display the Station menu.

2. Press the [3] key to select Scan Entry. The screen should look

7.3 Preparing Programs for Automatic Message

Transmission

This section shows you how to prepare the programs necessary for

automatic message transmission. The programs, which you can

save to a floppy disk for future use, enable unattended automatic

transmission.

The program for automatic transmission is called a macrofile. You

will need several types of macrofiles depending on the MARITEX

service to be utilized.

Commands

The tables which follow describe the commands for automatic trans-

mission.

Table 7-2 describes the commands processed by the DP-6.

equipment unless totally

familiar with electrical

circuits.

Hazardous voltage which can

cause electrical shock, burn or

serious injury exists inside the

equipment.

8.1 Maintenance

Regular maintenance is important for good performance. A regu-

lar maintenance program should be established and should at least

include the following:

Cleaning the Equipment

Wipe of accumulated dust from the equipment with a soft cloth.

An anti-static cleaner may be used to clean the screen of the termi-

nal unit. Do not use commercial cleaners to clean the equipment.

They can remove paint and markings.
