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.

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。

Observers believe the Chinese are hard at work developing a homegrown advanced standard, known as TD-SCDMA (time division synchronous cdma), and that 3G licenses will appear once TD-SCDMA is ready.

Crosswave uses synchronous optical network (sonet) and wavelength division multiplexing (dwdm) technologies, which enable it to transmit data at high speeds over long distances with a high degree of reliability.
