To establish and maintain for the purpose of providing direct facsimile communications between their national Nuclear Risk Reduction Centers, established in accordance with Article 1 of this Agreement, hereinafter referred to as the national Centers, an INTELSAT satellite circuit and a STATSIONAR satellite circuit, each with a secure orderwire communications capability for operational monitoring. In this regard:
(a) There shall be terminals equipped for communication between the national Centers;
(b) Each Party shall provide communications circuits capable of simultaneously transmitting and receiving 4800 bits per second;
(c) Communication shall begin with test operation of the INTELSAT satellite circuit, as soon as purchase, delivery and installation of the necessary equipment by the Parties are completed. Thereafter, taking into account the results of test operations, the Parties shall agree on the transition to a fully operational status;
(d) To the extent practicable, test operation of the STATSIONAR satellite circuit shall begin simultaneously with test operation of the INTELSAT satellite circuit. Taking into account the results of test operations, the Parties shall agree on the transition to a fully operational status.
To employ agreed-upon information security devices to assure secure transmission of facsimile messages. In this regard:
(a) The information security devices shall consist of microprocessors that will combine the digital message output with buffered random data read from standard 5 1/4 inch floppy disks;
(b) Each Party shall provide, through its Embassy, necessary keying material to the other.
To establish and maintain at each operating end of the two circuits, facsimile terminals of the same make and model. In this regard:
(a) Each Party shall be responsible for the purchase, installation, operation and maintenance of its own terminals, the related information security devices, and local transmission circuits appropriate to the implementation of this Protocol;
(b) A Group III facsimile unit which meets CCITT Recommendations T.4 and T.30 and operates at 4800 bits per second shall be used;
(c) Direct facsimile messages from the USSR national Center to the U.S. national Center shall be transmitted and received in the Russian language, and from the U.S. national Center to the USSR national Center in the English language;
(d) Transmission and operating procedures shall be in conformity with procedures employed on the Direct Communications Link and adapted as necessary for the purpose of communications between the national Centers.
To establish and maintain a secure orderwire communications capability necessary to coordinate facsimile operation. In this regard:
(a) The orderwire terminals used with the information security devices described in paragraph (a) of Article 2 shall incorporate standard USSR Cyrillic and United States Latin keyboards and cathode ray tube displays to permit the exchange of messages between operators. The specific layout of the Cyrillic keyboard shall be as specified by the Soviet side;
(b) To coordinate the work of operators, the orderwire shall be configured so as to permit, prior to the transmission and reception of messages, the exchange of all information pertinent to the coordination of such messages;
(c) Orderwire messages concerning transmissions shall be encoded using the same information security devices specified in paragraph (a) of Article 2;
(d) The orderwire shall use the same modem and communications link as used for facsimile message transmission;
(e) A printer shall be included to provide a record copy of all information exchanged on the orderwire.
To use the same type of equipment and the same maintenance procedures as currently in use for the Direct Communications Link for the establishment of direct facsimile communications between the national Centers. The equipment, security devices, and spare parts necessary for telecommunications links and the orderwire shall be provided by the United States side to the Soviet side in return for payment of costs thereof by the Soviet side.
To ensure the exchange of information necessary for the operation and maintenance of the telecommunication system and equipment configuration.
To take all possible measures to assure the continuous, secure and reliable operation of the equipment and communications link, including the orderwire, for which each Party is responsible in accordance with this Protocol.
To determine, by mutual agreement between technical experts of the Parties, the distribution and calculation of expenses for putting into operation the communication link, its maintenance and further development.
To convene meetings of technical experts of the Parties in order to consider initially questions pertaining to the practical implementation of the activities provided for in this Protocol and, thereafter, by mutual agreement and as necessary for the purpose of improving telecommunications and information technology in order to achieve the mutually agreed functions of the national Centers.
This Protocol shall enter into force on the date of its signature and shall remain in force as long as the Agreement Between the United States of America and the Union of Soviet Socialist Republics on the Establishment of Nuclear Risk Reduction Centers of September 15, 1987, remains in force.
