A method for multi-path TDM data transmission includes: applying a plurality of high-speed serial lines to connect a center switch network board to a plurality of service boards; multiplexing multi-path TDM data from the center switch network board at transmitting side, and transmitting TDM data multiplexed in batch via one of the high-speed serial lines to one of the service boards; at receiving side, serial receiving the TDM data multiplexed and de-multiplexing the TDM data multiplexed to multiple TDM paths. The TDM bridge connector includes: a TDM high-speed serial transmitting adaptive circuit, and a TDM high-speed serial receiving adaptive circuit and a clock control circuit. The invention increases greatly transmission capacity and looses the requirement of clock synchronization, so the system reliability is greatly raised.

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

The present invention discloses a method for logically binding and verifying a subassembly in equipments. The method sets the subassembly in the equipment as a sub-module, and setting a main module in the equipment. the sub-module stores individual information of its own and the main module stores the individual information of the sub-module. The main module sends verification information corresponding to the individual information of the sub-module stored in the main module to the sub-module when the sub-module needs to be verified. The sub-module judges whether the received verification information matches the individual information stored by the sub-module itself after receiving the verification information, if they matches, it is determined that the sub-module is in the legal status, otherwise, it indicates that the sub-module is in the illegal status. The burglarproof technique for the equipment in the present invention can be extended from the level of equipment to the subassemblies, and the present invention has broad applications.
