Abstract
In a telecommunications duplicated synchronous switch where switching in bit synchronism is carried out and fault detection is by discrepancy checking between the duplicate switch planes, determination of the faulty plane is provided by the data being carried in switched bytes grouped into data frames, each frame carrying check data in respect of data from an earlier frame. Corruption of data in a frame is thus indicated by information in a later frame.
