ABSTRACT:
In a switching system including an alternative routing function, a maintenance terminal compiles an alternative routing scenario into a compiled alternative routing scenario. Connected to the maintenance terminal and an exchange switch for carrying out an exchange operation, an exchanging CPU carries out control of alternative route connection in accordance with the compiled alternative routing scenario to control the exchange switch when one of a fault and a congestion occurs in the leased line. The exchange CPU includes a maintenance terminal interface for receiving the compiled alternative routing scenario from the maintenance terminal. A basic connection control device produces a notification signal related to a leased line and an alternative line and carries out a basic connection control. An alternative routing scenario executing device stores the compiled alternative routing scenario therein executes alternative routing in accordance with the compiled alternative routing scenario in response to the notification signal by supplying the basic connection control device with an instruction signal.
