It has an M function. The multiplexing / demultiplexing circuit 5 has a multiplexing / demultiplexing function according to a multiplexing rule defined by CCITT.
The multiplexer / demultiplexer circuit 6 is a cell-based multiplexer / demultiplexer circuit, and when the highway is empty, the ATM terminating circuit 4 which has a cell to be transmitted transmits a cell to perform multiplexing and compete on the highway. In this case, priority control such as first-come-first-served control is performed. The separation is performed according to the address of the ATM signal. The multiplexer / demultiplexer circuit 7 is a multiplexer / demultiplexer circuit according to the multiplexing rule defined by CCITT, like the multiplexer / demultiplexer circuit 5, and an explanatory diagram thereof is shown in FIG.

The transmission line terminating circuit 8 is a transmission line interface circuit,
The input / output terminal 9 is an input / output point of the terminal device. Therefore, since there are multiple paths in the transmission line body, the STM is used for each path.
Signals and ATM signals can be assigned to ST
