the pavement to bring immediate service to a few hundred police telephone lines. Workers from throughout the country, including 3,000 Verizon employees plus non-Verizon employees, helped restore service, allowing the network to carry 230,000,000 calls during the first week following the attacks. During the restoration efforts, trunk cables were run out windows and down the side of the building, flowing through streets closed to traffic, until they found an undamaged manhole for them to enter. DMS-100 and other exchange equipment was damaged and replaced the following year. The building was completely renovated restoring it to its former glory as corporate headquarters. In a ceremony on December 8, 2005, Verizon moved its corporate headquarters from 1095 Avenue of the Americas to 140 West St. In later years the company sold parts of several exchange buildings, and returned its headquarters to 1095 Avenue of the Americas.
