A SHARED BUS DISTRIBUTED INTERCROSS DEVICE

摘要

A distributed cross device with a shared bus is composed of a plurality of service single boards. Each service single board is connected with another one via an internal distributed space division cross matrix module and an external cross shared bus. The service single board includes: a space division cross matrix module, a client service processing module and a line service processing module. The shared bus is used to connect space division cross matrix modules of all the service single boards. The service signals of each service single board can be scheduled to the shared bus and transmitted to a space division cross matrix module of another service single board by its space division cross matrix module.
