ANNEX
TO THE MEMORANDUM OF UNDERSTANDING BETWEEN THE UNITED STATES OF AMERICA AND THE UNION OF SOVIET SOCIALIST REPUBLICS REGARDING THE ESTABLISHMENT OF A DIRECT COMMUNICATIONS LINK
The direct communications link between Washington and Moscow established in accordance with the Memorandum, and the operation of such link, shall be governed by the following provisions:
1. The direct communications link shall consist of:
a. Two terminal points with telegraph-teleprinter equipment between which communications shall be directly exchanged;
b. One full-time duplex wire telegraph circuit, routed Washington-London-Copenhagen- Stockholm-Helsinki-Moscow, which shall be used for the transmission of messages;
c. One full-time duplex radiotelegraph circuit, routed Washington-Tangier-Moscow, which shall be used for service communications and for coordination of operations between the two terminal points.
If experience in operating the direct communications link should demonstrate that the establishment of an additional wire telegraph circuit is advisable, such circuit may be established by mutual agreement between authorized representatives of both Governments.
2. In case of interruption of the wire circuit, transmission of messages shall be effected via the radio circuit, and for this purpose provision shall be made at the terminal points for the capability of prompt switching of all necessary equipment from one circuit to another.
3. The terminal points of the link shall be so equipped as to provide for the transmission and reception of messages from Moscow to Washington in the Russian language and from Washington to Moscow in the English language. In this connection, the USSR shall furnish the United States four sets of telegraph terminal equipment, including page printers, transmitters, and reperforators, with one years supply of spare parts and all necessary special tools, test equipment, operating instructions, and other technical literature, to provide for transmission and reception of messages in the Russian language.
The United States shall furnish the Soviet Union four sets of telegraph terminal equipment, including page printers, transmitters, and reperforators, with one years supply of spare parts and all necessary special tools, test equipment, operating instructions and other technical literature, to provide for transmission and reception of messages in the English language.
The equipment described in this paragraph shall be exchanged directly between the parties without any payment being required therefor.
4. The terminal points of the direct communications link shall be provided with encoding equipment. For the terminal point in the USSR, four sets of such equipment (each capable of simplex operation), with one years supply of spare parts, with all necessary special tools, test equipment, operating instructions and other technical literature, and with all necessary blank tape, shall be furnished by the United States to the USSR against payment of the cost thereof by the USSR.
The USSR shall provide for preparation and delivery of keying tapes to the terminal point of the link in the United States for reception of messages from the USSR. The United States shall provide for the preparation and delivery of keying tapes to the terminal point of the link in the USSR for reception of messages from the United States. Delivery of prepared keying tapes to the terminal points of the link shall be effected through the Embassy of the USSR in Washington (for the terminal of the link in the USSR) and through the Embassy of the United States in Moscow (for the terminal of the link in the United States).
5. The United States and the USSR shall designate the agencies responsible for the arrangements regarding the direct communica-tions link, for its technical maintenance, continuity and reliability, and for the timely transmission of messages.
Such agencies may, by mutual agreement, decide matters and develop instructions relating to the technical maintenance and operation of the direct communications link and effect arrangements to improve the operation of the link.
6. The technical parameters of the telegraph circuits of the link and of the terminal equipment, as well as the maintenance of such circuits and equipment, shall be in accordance with CCITT and CCIR recommendations.
Transmission and reception of messages over the direct communications link shall be effected in accordance with applicable recommendations of international telegraph and radio communications regulations, as well as with mutually agreed instructions.
7. The costs of the direct communications link shall be borne as follows:
a. The USSR shall pay the full cost of leasing the portion of the telegraph circuit from Moscow to Helsinki and 50 percent of the cost of leasing the portion of the telegraph circuit from Helsinki to London. The United States shall pay the full cost of leasing the portion of the telegraph circuit from Washington to London and 50 percent of the cost of leasing the portion of the telegraph circuit from London to Helsinki.
b. Payment of the cost of leasing the radio telegraph circuit between Washington and Moscow shall be effected without any transfer of payments between the parties. The USSR shall bear the expenses relating to the transmission of messages from Moscow to Washington. The United States shall bear the expenses relating to the transmission of messages from Washington to Moscow.
