Abstract

PURPOSE: To test the normal properties for exchange of circuits by simulating transmission/reception of data among subscribers via a single test equipment.
CONSTITUTION: A subscriber terminal 1 transmits/receives data and the circuit of the terminal 1 stored in a subscriber circuit 3 is switched to the circuit of a test terminal 4. The data are transmitted through the terminal 4 and supplied to a subscriber circuit 7 through a circuit exchange 6 via an interface device 5 and the circuit 3. Then the data are received by the terminal 4 via the device 5. In a reception test mode the data are sent through the terminal 4 and supplied to the circuit 3 through the exchange 6 via the device 5 and the circuit 7. Then the data are received by the terminal 4 via the device 5.
