Interference faults testing for time switches
Jerzy Tyszer · IEEE Transactions on Communications · 1990
A detection scheme for coupling faults for integrated digital time-division switches is proposed. It is shown that a low overhead is necessary to improve fault detectability. Based on the proposed augmentation of a standard time switch, a new test procedure that possesses the following properties is developed: it guarantees a detection of all possible coupling faults in both data and control memory, and the number of tests is minimal. >
