A Fault tolerant system is one that can continue to correctly perform its specified tasks in the presence of hardware failures and software errors. This paper discribes hardware redundancy of fault tolerant methods used in the present digital switching systems, and proposes several new fault tolerant methods for digital switching systems. In addition, are compared and analyzed reliabilities between thr present and the new facult tolerant methods.
