Abstract
A method for detecting an erroneous IF board mounting in a transmission device which can be employed even when one-to-one correspondence is not established for slots on a transmission device and normally mounted IF boards determines when the transmission device is activated, for each of transmission channel interfaces, whether or not a plurality of types of packages having different transmission speeds are mounted. When a plurality of types of packages having different transmission speeds coexist at one of the transmission channel interfaces, it is concluded that all the packages in the transmission channel interface are erroneously mounted.
