Abstract
A switched digital circuit is used to restore a failed dedicated digital circuit to a remote station in conjunction with reconfiguration of the network's multipoint junction units (MJU). A circuit is established over the public switched digital network from the customer's central location to a remote station requiring restoral. The remote station is then connected back to the dedicated multipoint circuit, at the telephone company central office facilities, by way of digital cross connects and MJUs that perform the digital bridging. The switched digital access line, from the customer central location to the telephone company facilities is then available for use in establishing switched connections to the other remote stations. The process is sequentially repeated for each dedicated digital circuit to a remote station to be restored, thus conserving hardware required at the customer premises and minimizing the number of dial up switched digital access lines needed at the customers central location.
