CHAPTER Ill, SECTION 7 per month (including the reproduction work -requested by the Honolulu Office). RECORDS CENTER The AEC rated in May, July 1953, 56 warded to the Records Program was inaugu1952 on a part-time basis. By 1 records schedules had been forSanta Fe Operations Office for approval; 415 cubic feet of records were for- warded to less expensive storage facilities; 220 cubic feet of records were transferred to the AEC Records Service Center at Los Alamos, New Mexico; and 149 cubic feet of records were destroyed. A full-time Records Officer was appointed on 1 July 1953, at which time the H&N Records Center started operating on a full-time basis. By the end of 1953, the Records Center holdings totaled 861 cubic feet, or double the amount reported for the preceding six months. Reference services furnished from Records Center to the Home Office amounted to 83 in 1952, and 1,086 in 1953. The monthly average of reference services from 1 July 1953 to the end of the year was 166. In 1954, a peak of 994 was reached during the month of April, then gradually decreased to 161 in June 1954. Investigations and studies regarding the possibility of microfilming all vital records were made. However, the space-saving advantage gained through the use of microfilm did not warrant the over-all cost of this undertaking in view of the fact that storage of vital records, by contractual agreement, need not exceed seven years. COMMUNICATIONS TELEPHONE. On 24 July 1953, the 120-posi- tion PBX in the Home Office was replaced with a 160-position board. Approximately 558 long distance calls a month were made over a sevenmonth period, including the peak period, and approximately 44,000 local calls were made for the same period. TELETYPE. Teletype communications between the Home Office and Eniwetok were effected by means of the radio teletype facilities in- stalled at the AEC Communications Center at Los Alamos and Eniwetok. All classified and unclassified messages were sent over this means by TWX to Los Alamos, thence over the radio teletype circuit direct to Eniwetok. Incoming teletypes were relayed by this same means to Los Alamos, and then in turn relayed on to Holmes & Narver, Los Angeles, by TWX collect. During Operation IVY, classified messages to Eniwetok were encoded in the Contractor’s Home Office, then transmitted to Los Alamos. Los Alamos decoded and re-encoded the mes- sages for relay to the Task Group Communi- cations Center at Eniwetok Atoll. In October 1952, prior to the commencement of CASTLE, Page 3-36 a cryptographic system was issued for the Contractor’s use in Los Angeles, and for the Communications Center at Eniwetok. This system enabled H&N to send and receive messages classified Restricted, Confidential, and Secret without the delay involved in having Los Alamos decode and re-encode these messages. “Back-up”? communication circuits were available in the event of failure of the radio teletype circuit. The “back-up” circuit operated from Los Alamos to the AEC Communications Center, Sandia; from there messages were sent over Military circuits to Fort Sam Houston, Texas, thence through the Sixth Army Headquarters at San Francisco. From San Fran- cisco, messages were sent by Military radio teletype to the Communications Center at Oahu and from there to Eniwetok. In July 1953, due to continued adverse at- mospheric conditions resulting in the failure of the radio teletype circuit between Los Alamos and Eniwetok, Holmes & Narver was advised to file unclassified messages with the Army Communications Center in Los Angeles. These messages were then relayed to the Sixth Army Headquarters Communications Center, San Francisco, where they were sent by Military radio teletype to Oahu, and thence to Eniwetok and. or to H&N’s office in Honolulu. In March 1953, the Holmes & Narver Message Center in the Home Office was officially recognized by the Military as a “trained TWK tributary station of the Los Angeles Communications Center.” As a result of this recognition, H&N was furnished Military Procedure Publications which enabled the Message Center to operate efficiently and in accord with other units of the circuit. The Army Communications Center at Los Angeles was unable to accept Holmes & Narver classified messages prior to 5 April 1954 due to Military regulations governing encoded mes- sages sent over TWX equipment. This equip- ment was, until that date, the type of equipment installed at the Home Office. The filing of classified messages continued through Los Alamos. However, after 5 April 1954 new equip- ment, formally known as an AKAN circuit, was installed at the Holmes & Narver Home Office, and encoded messages were permitted via a leased line to the Army Communications Center in Los Angeles. To expedite procurement, teletype facilities were also employed between the Contractor and commercial companies within the United States. The peak in H&N’s teletype traffic was established during the months of August and September. A monthly breakdown of the teletype traffic transmitted and received for the
