A transmission apparatus has a main signal processing device, a monitor control part and an intermediating part to intermediate addresses and data between the monitor control part and the main signal processing device. The transmission apparatus further has a first switching part to selectively supply the address or the address and the data output from the intermediating part to the main signal processing device in the normal operation mode, and to selectively supply the address or the address and the data output from the monitor control part to the main signal processing device in the debug mode, and a second selecting part to selectively supply the data output from the intermediating part to the monitor control part in the normal operation mode, and to selectively supply the data output from the main signal processing device to the monitor control part in the debug mode.
