A line relay device, a functional part of the White House telephone system from August 1966 to May 1986, under five administrations: Lyndon Johnson, Richard Nixon, Gerald Ford, Jimmy Carter and Ronald Reagan. It was presented encased in rectangular clear acrylic block within a fitted custom box. An accompanying presentation letter from Thomas M. Gibbons, President of C&P Telephone, to Christopher Hicks, General Counsel to the U.S. Department of Agriculture, dated May 1, 1987, describes the device and its history. A caption imprinted in blue on the clear acrylic block describes the device:
This line relay was part of the Centrex Telephone System installed in the White House in August, 1966. The system provided telephone communications in excess of 250 million calls while supporting five United States presidents. This system was replaced by a digital Centrex system in May, 1986.
