104-10414-10124: MEXICO CITY STATION HISTORY
LISAMPAN, an audio penetration of the Cuban compound, began when the Mexico City station learned that "LIFEUD-2 (LIFEAT project) would have access to the Cuban compound in connection with a modernization program of the telephone system." The installations were supervised by David Wilsted, American principal agent of the LIFEAT project, who in turn was directed by the inside case officer for the project, Michael J. Farmer, and the station's technical officer. It should be noted that LIFEAT had a second telephone lineman, LIFEUD-3. The two of them set up LISAMPAN as well as a penetration of the Soviet TELEX system, described here in the history: https://www.maryferrell.org/showDoc.html?docId=146763&relPageId=95&search=%22lifeud-2%22
