Abstract
A network system of the present invention has a TDM network including TDM switches and an ATM network including communication devices connected the TDM switches. Each of the communication devices comprises a first call setting unit setting, when receiving a call setting request from the transmitting side TDM switch, a call between this communication device and the receiving side communication device, a specifying unit specifying, if the first call setting unit is unable to set the call, any one of TDM switches as a detour TDM switch, a storing unit stored with detour information for setting the call between the detour TDM switch and the receiving side TDM switch, a reading unit reading the detour information when the specifying unit specifies the detour TDM switch, a second call setting unit setting a call between the communication device and a detour communication device, and a unit making, when the second call setting unit sets the call, the detour communication device transmit a call setting request containing the detour information read by the reading unit to the detour TDM switch.
