PURPOSE:To easily current an error in setting by detecting and displaying an erroneous combination of a physical channel to an arrival signal handling device provided in a device, and a logical channel for signal processing in the device. CONSTITUTION:A physical address generated by a channel address generating circuit 101 is supplied to a combination setting circuit 102, an address selecting circuit 105, and a data holding circuit 107. An error detecting circuit 104 compares the signal output of the setting circuit 102 with that of a frame address generating circuit 103 to detect coincidence between the physical and logical addresses of a unit frame, and decides on erroneous setting when there are >=2 pulses, thereby detecting a setting state which corresponds to the physical address. This setting state information is written in a physical address of a storage circuit 106 which is selected by the address setting circuit 105, and then read out of the same physical address to be sent to the data holding circuit 107. |
