Abstract
The present invention relates to an apparatus for verifying a data path through a digital switch between a transmitting port and a receiving port. The apparatus comprises a transmitter which transmits a test data block in a first predetermined time slot which corresponds to the time slot associated with the transmitting port. A receiver receives the test data block in a second predetermined time slot, which corresponds to the time slot associated with the receiving port. Test logic examines the received test data block to determine that the test data block has been transmitted error-free through the digital switch thereby verifying the data path.
