-In 1963 or 1964, Socorro was selected as an L-3I Main Station, where electricity was rectified and injected on the L-3I cable and calls were multiplexed and demultiplexed on the cable. Socorro was also selected as a regional phase synchronization master for the L-carrier. To meet L-3I hardening standards, this entailed building an underground vault of several thousand square feet with provisions to survive a nuclear strike five miles away. Likely at the same time, Socorro was selected to serve as an AUTOVON switch, which also required hardening.+In 1963 or 1964, Socorro was selected as an L-3I Main Station, where electricity was injected on the L-3I cable and calls were multiplexed and demultiplexed on the cable.

 The several thousand square foot vault would have had about three staff members at any given time, and multiple shifts served the site to provide 24/7 operations coverage. Access was via one of the buildings at ground level that appears to be a garage but has vents around the roofline, this building is of a standard design and can be used to recognize other L-3I underground sites across the country. The several thousand square foot vault would have had about three staff members at any given time, and multiple shifts served the site to provide 24/7 operations coverage.
