Method based on backboard transmitting time division multiplexing circuit data and a bridge connector

摘要

The invention discloses a method for multi-path TDM data transmission based on backplane and a TDM bridge connector for implementing the method. The method includes: applying a high-speed serial line on backplane to connect a center switch network board and service boards; multiplexing or interleaving multi-path TDM data at transmitting side, and then transmitting in batch to said high-speed serial line on the backplane; at receiving side, serial receiving said data and de-multiplexing or de-interleaving them to multiple TDM paths. The TDM bridge connector includes: a TDM high-speed serial transmitting adaptive circuit, a TDM high-speed serial receiving adaptive circuit and a clock control circuit. The invention increases greatly transmission capacity on backplane and looses the requirement of clock synchronization, so the system reliability is greatly raised.
