<p>A transmission system is provided which multiplexes and transmits synchronous data and asynchronous data, while maintaining the communication quality required of synchronous data and of asynchronous data respectively. A tag having information used to identify the data as synchronous data or as asynchronous data is added to both synchronous data and to asynchronous data. Tags added to each data item are extracted, and based on the information contained in the tag, each data item is identified as synchronous data or as asynchronous data, and synchronous data is transferred to a time-division switch, while asynchronous data is transferred to a packet switch.</p> |
