因为它是一种异步的机制，ATM与同步传输模式理论（比如时分复用技术，它为每个用户预定义了时间片）并不相同。

Because it is an asynchronous mechanism, ATM differs from synchronous transfer mode methods, where time-division multiplexing techniques are employed to preassign users to time slots.

最后，给出了高速模式下块传输和同步传输的测试数据。

At last a test report about bulk transfer and isochronous transfer in high - speed mode is given.
