  • System for converting a No. 5 crossbar telephone switching central office to a conforming equal access central office
    Patent number: 4685127
    Abstract: A method of providing equal access to a number of long distance carriers in local telephone company office containing No. 5 crossbar switching machines. Calls are intercepted between the line link frame and the originating registers. If the call is a long distance call, a serial number which resembles a conventional phone call is inserted in the calls place. The called number is stored and the appropriate carrier is determined by locating the calling party's pre-selected carrier choice in telephone company records. When the call identified by the serial number exits the switch it is automatically routed to the correct long distance carrier.
