| 单词 | TDM (Time-Division Multiplexing) |
| 释义 | TDM (Time-Division Multiplexing) mux prepends the frame with a framing bit that delineates that frame from another, and is used by the multiplexers and other intermediate devices for purposes of synchronization and, in some cases, for various signaling and control purposes. This process occurs 8,000 times a second at the precise pace of 125µs (microseconds), with the pace driven by the demands of PCM voice. At the receiving end of the circuit, the process is reversed. As the paired muxes are tightly synchronized, each channel in each frame is identified, the individual transmissions are de-multiplexed, and each is forwarded over the port to which the intended receiving terminal device is attached. See also FDM and STDM. |
