  • System and method for recovering from a telecommunications disaster
    Patent number: 5465294
    Abstract: A telephone disaster recovery process for quickly re-establishing long distance telephone service to a telephone LEC office after a telephone central office connected to the LEC office has been rendered inoperable by a disaster is described. The central office is located at a disaster site. The process operates by assessing the disaster and identifying elements of an on-site component needed to address the disaster. The elements of the on-site component are transported to the disaster site, and are mapped to corresponding elements of the inoperable central office. These elements of the on-site component are configured and interconnected according to the mapping to enable the on-site component to functionally emulate the inoperable central office. Then, the on-site component is connected to the LEC office, and is also connected to an off-site component using communication media in a long distance telephone network.
