Abstract

PURPOSE:To reduce the danger due to passing through an alternative route in terms of the connection time by extremely increasing the possibility for connection passing through a 1st route. CONSTITUTION:An optimum route Ra reaching the incoming station of the call originated from a switchboard 1 is connected to this switchboard 1 together with a detouring route Rb set against the route Ra, a circuit 300 having the same communication speed as the call included in the route Ra, a circuit 400 having another communication speed which allows the communication speed of the call, and a circuit 500 having the same communication speed as that of the call included in the route Rb. A detouring route selection means 600 of the switchboard 1 selects the circuit 400 having another communication speed included in the route Ra with higher priority than the circuit 500 when the circuit 300 is completely busy. Then the means 600 informs the communication speed of the call to the incoming station. As a result, the applicable circuit range is increased on the 1st route.
