JAPAN-PRC SATELLITE PHONE HOOKUP JArII~lED BY THIRD COUNTRY
OW061255 Tokyo MAINICHI DAILY P~~WS in English 4 Oct 80 p 12
, [TextJ International telephone communications via a communications satel-
lite, link;.ng Japan and China, were recently jammed bq a mysterious radio
wave, the Posts and Telec~~runications Ministry has disclosed.
Ministry officials said this was the first time a satellite co~unication
telephone service had been disrupted by an unidentified radio wave.
They said the incident, which affected the communication for some 30 minutes,
occurred at a time when Japanese experts were investigating a recent cutoff
of undersea cable lines between the two countries.
It is expected that experts from the two countries will discuss the matter
and map out countermeasures in Shanghai shortly.
The officials disclosed that the telephone communication was jaffined Septem-
ber 25 between 7.43 and 8.14 p.m. The jamming occurred one day after the
undersea cable lines were found ~ut at a point off Kumamoto Prefecture.
A KDD monitoring station in I:~araki Prefecture reported that it could not
receive the co~unications for about 30 minutes because of ~a~ing. The
station was unable to find the exact source of the problem.
Japanese and Chinese C~lecommunications officials determined that a myster-
- ious jamming was made by a third country.
Taking a serious vie~ of the incident, the ministry has reported it to the
Intelsat Operation Center in the United States for fear that telephone
communications via the Intelsat satellite.which is stationary over the
_ Pacific would be jammed in the future.
On the other hand, undersea cables linking Japan and China have been cut
off five times since the first incident was reported in 1978. The Japanese
_ ministry has asked the Maritime Safety Agency to step up its patrol around ,
the area where undersea calbes are laid.

SATEI'~ITE SYSTEM FOR NEWS RELAY TO BE TESTED NEXT MARCH
OW041401 Tokyo THE DAILY YOMIURI in English 3 Oct 80 p 2
[Text] A newly developed satellite transmission system for newspaper use
to be tested from next March would allc~w remote areas to get the same late-
breaking news stories carried in late editions for large cities.
_ At the suggestion of the YOMIURI SHIMBUN, the planned experiments will be ~
jointly undertaken by Nihon Shimbun Kyokai (The Japan Newspaper Publishers
and Editors Association) and the Radio Research Laboratory of the Posts and
Teleco~unications Ministry.
The stationary communications satellite "Sakura," which the U.S. put into
sationary orbit above the ~quator in 1977 for Japan, will be used for the
tests. Similar satellite transmission is already being used in the U.S.
The projected tests follow the recent development by the Radio Research
Laboratory of an ultrasmall grotmd statian for sending and receiving the
_ transmission waves.
Named single channel per carrier (SCPC) system, the new ground station with
capacity equivalent to a single telephone circuit is the smallest of its
kind iz the world. It is two meters high, one meter wide and weighs 450
kilograms. Unlike the large-capacity ground station as used for the U.S.
t:Ansmission system, the SCPC with a one-meter-diameter parabolic antenna
is movable aboard a truck, according to the research laboratory. In the
planned experiments, an SCPC will be installed atop the Tokyo headquarters
building of the YOrffURI SHIMBUN.
_ '!'he NIHON KEIZAI SHIMBUN will transmit signals for reproduction of news
items, and "Sakura" will relay the signals to the SCPC via the radio re-
search laboratory's Kashima station in Ibaraki-ken.

TELEGRAPH Ai1D FACIMILE COi~II~1UNICATIONS AT THE 1980 OL.YMPICS
Moscow ELEKTROSVYAZ' in Russian No 7, 1980 pp 1-3
[Article by N. i~I. Korsakov]
[TextJ At the 1980 Olympics, important significance has been attached to
the document forms of communication - telegragh and facimile permitting
_ relatively high reliability of the transmitted information to be obtained.
i
In accordance with the organizational scheme-for the Olympics communications
developed by the Giprosvyaz' Institute [1-3], a station for information
gathering and processing at the USSR Central Telegrapt~ Office, teletype
machines at the riain Press Center (G.P.Ts) and 25 subpresscenters at the
Olympica sports facilities have been built. One of the 9lympic sites the
new Central Telegraph building is shown in Figure 1[not includedJ.
At the GPTs center and the suppress centers, foreign correspondents and also
representatives of foreign television and radio companies will be able to
_ transmit information to their addressees over the Teleks [Telex] network
using teletype machines installed in the equipment rooms. The access of the
teletype to the international Telex network will be through the new inter-
national electronic switching office insta:.led at the Central Telegraph
. Office of the USSR especially for the Olympic Game~. The machines included
in the Moscow Autcmatic Office were installed for correspondents working
- with the intra-Soviet subscriber telegraph network.
In order to accelerate the transmission and decrease the time that the tele-
graph channel is busy, the information must first be punched. For this pur-
pose provision is made for special equipment in the t~letype rooms. The
- punching, setting up the addressee number and transmission of the prepared
information on the punchtape can be done by the correspondents independently,
or all of these operations will be performed hy the Central Telegraph per-
sonnel with payment for the operations by the correspondent in accordance
with the established rate.
For servicing of the correspondents at the 1980 Olympics broad use has been
made of facimile communications. The high--speed Infotek-6000 equipment
(built by the Federal Republic of Germany) is used to connect the GPTs

gous equipment. Thj.s connectior is made by the long distance patch through
tlie international telephone office and the Layon cross,bar-type automatic
~ffice which includes the Infotek--6000 telEphone equipment. All of the
data transmission operations on the Infotek-60~0 equipment are performed by
the Central Telegraph enployees.
For processing the e;~cess vo2ume of i~~Formatiou from the press centers when
it cannot be tran~mitted at once L-o the destination equipment of the Telex
and Intotek-o000 equipment, there is a Data Gathering and Processing Office
- (Figures 2, 3[not reproduced]), The ebcess information from the press cen-
ters transmitted to the office using the Infotek-6000 equipment is punched
on the telegraph equipment and then transmitted to the destination office
over the Telex netcaork or over the direct international telegrap~i communi-
cations.
The largest. volume of telegraph equipment is concentrated at the GPTs and
at the Information Gathering aud Processing Oifice, Some 95 and 88 tele-
types connected to the Telex network and 42 and 32 pieces of Infotek-6000
equipm~nt are installed there, respectively. At the Information Gathering
and Processing Office 150 telegraph.machines are used for punching informa-
tion received from the GPTs and the subpress centers.
Ten teletypes from the Telex r.etwork and 14 Infotek-6000 sets are connected
to the teletype rooms of the five subpress centers in the Luzhniki sports
complex. The largest subpress center at Luzhniki has been organized in the
Great Sports Arena; there are 5 teletypes and 6 Infotek-6000 sets here.
Fight Telex teletypes and 6 Infotek-6000 sets have been installed at the
two subpress centers of the sparts complex on Mir Prospekt, including 5 and
3 at the subpress center of the Olimpiyskiy [Olympic] Stadium, respect3.vely. ~
At the three subpress centers of the sports complex in Krylatskiy there are
4 telex teletypes and 7 Infotek-6000 sets, including 2 and 3, respectively,
at the Grebnoy channel subpress center. At the remaining subpress centers
there are one or two Z'elex teletypes and two Infotek-6000 sets each.
The Telex teletypes are connected to the international electronic AKhV-20
switching off ice of the Eriksson Company (Sweden) telegraph channels orga-
nized ~oith the help of the TVU-12 equipment (installed at the GPTs center)
and the DATA-3P0 and DATA-6P0 equipment (at the subpress centers). The
I~ifotek-6000 equipment at the GPTs center and the subpress centers is connec-
ted to the Infotek-6000 equipment at the Information Gath.ering and Process-
ing Office by rhe direct lines of the city telephone exchange trunks. A
1?rge bunch of telegraph channels has been organized between the Central
Telegraph and ~he Ulympics television and radio complex buildings where
the Telex network equipment is located; direct tele~raph channels have baen or-
ganized for foreign tQlevision and radio rooms under lease agreements.
The T-100 teleeype machines bullt in Czechoslovak:La are being used in the
Main Press Center and the subpress centers of the 1980 Olympics for punch-
ing and transmitting information uver the Telex network. They are made in
the two-register version (Roman characters and numbers), and they operate

at a speed of 5Q baud. The T-lOQ teletype baa a builtin punchtape trans-
mission device (transmitter) and punch and also a ringing set.
The new RTA-80 Soviet-made electronic teletypes are bein~ used to transmit
information over the subscriber telegraph network inside the country. The
equipment can be operated at speeds of 50. and 100 baud. The speeds are
switched by pressing one key. The teletype has a photoreader, punch and
?~uiltin ringing set permitting a number to be dialed directly from the key-
board.
The Infotek-6000 facimile equipment insures high-speed transmission of line
originals over the voice-frequency channel. The technical specifications
for the equipment are as follows: scanning procedures planar; recording
electrostatic; transmission phase-amplitude mod~:lation over the voice-
frequency channel with 1800 hertz carrier; transmission time of one sheet
(format A-4) and frame resolution during operation in the following modes:
Express 35 seconds, 2.7 lines/r~.~~n; Standard 1 minute, 4 lines/mm; De-
*_ail 2 minutes, 8 lines/mm; line resolution 8 lines/mm.
The TVU-12 equipment is designed for transmission of both start-stop and
synchronous signals of any code with a telegraph speed of up to 200 baud.
The equipment us,es the principle of time sharing oF the channels with pulse-
amplitude keying of the signals in the individual telegraph channels; 12
two-way telegraph cha~els operate on one four-wire physical network each.
The distortions introduced by the equipment do not exceed 3% at a speed of
50 baud and 6% at a speed of 200 baud. The direct range of communications
is 6 to 12 km.
The DATA equipment the duplex subscriber telegraph is designed for
operation over the two-wire GTS jcity telephone exchange] physical cable
circuits. The equipment has two vErsions DATA-3 and DATA-6 and it _
provides for the organization of three or six telegraph channels respec-~
tively. The principle of time sharing of the channels with pulse-code modu-
lation of the signals in individual channels is used. The group transmission
rate over the GTS line is 2400 baud (DATA-3) and 4800 baud (DATA-6). The
direct communication range with the DATA-3 equipment is 18 km, and with
DATA-6, 13 }an. The degree of isochronous distortions introduced by the
DATA channels at a speed of 50 baud is no more than 4%, and at a speed of
100 and 200 baud, no more than 7%.
The Telex teletypes of all Olympic sites are connected to the AKhV-20 inter- _

[Text] The equipment for digital transmission of sound broadcast signals
(ATsV) is designed for the organization of large bunches of sound broadcast
trunks on the intra-city segments of the network. The sound broadcast equip-
n~ent operates on. the line channels of the primary digital systems (II~I-30)
with a data transmission rate of 2048 kbits/second.
Up to 8 sound broadcast cha~nnels, each in a frequency band of 50 to 6400
hertz can be organized with respect to the f irst channel. Durin~ the
VII Spartakiad Games of the Peoples of the USSR in Moscow there were 120
sound broadca~t channels in operation organized by means of this equipment.
By the time of holding the Olympic Games the number af ATsV channels between
the sports complexes and the Olympics Switching Center (OKTs) reached 600.
The volume of equipment recalculated for standard bays with overall dimen-
sions of 2600 x 6Q0 ~'225 mm is 55 bays.
For comparison let us point out that when using the AB-2/3 equipment for
these purposes more than 1000 standard bays would be required, and when us-
ing the cable and radio relay broadcast line (UKRLV) equipment, about 40~
bays. The use of the trunk bays (SSL) requires laying of an expensive type
- TDS cable; in addition, the length of communications is limited to 17 km
at the same time as the ATsV permits transmission of information more than
50 laa over low-frequency telephone c3ble pairs with paper insulatian, type
T, TZ, TPP, and so on.
i The ATsV is the only sound broadcast signal transmission equipment not re-
yuiring adjustment and tuning either when putting it into operation ot dur-
ing operation and maintenance.
