Description of the Related Art Conventionally, a line setting method of this kind of multiplexer for digital communication has the same multiplexing information, that is, arrangement information required for line setting between opposite multiplexers, and this arrangement information is used. It is performed by multiplexing the original. For example, a fixed pattern of some placement information is shared by multiplex devices, and the pattern identifier is notified from one of the opposite devices to the other via the same line as the data, so that line multiplexing between the opposite devices can be performed. The conversion information is the same.

As shown in FIGS. 2 (a) to 2 (c), the transmission path signal has 80 bits as one block, and the first bit and the 8th bit from each block are arranged with data for synchronizing between the opposite devices. Of these, 1 bit is used for a channel (also referred to as a 2nd channel) for transmitting multiplexing information such as arrangement information between the multiplexers. When the data on the terminal side is transmitted to any of the remaining bits corresponding to 56 kbps other than the synchronization data in any of the arrangement patterns as shown in FIGS. 3A to 3C and the arrangement pattern is changed, 2nd is used. The channel is used to notify the other party of the pattern.
