An electronic, wired logic, scanner controlled PBX is disclosed having code leads which interconnect a system controller with line circuits, trunk circuits, and registers. The controller applies signals to the code leads to identify a calling line circuit at the initiation of a call. A register stores both the calling and called numbers and gates this information onto the code leads at different times to identify the calling and called lines, respectively. The identification and selection signals applied to the code leads are also transmitted as path establishment signals to a network controller. |
