Zusammenfassung:Disclosed is a circuit for the automatic testing of channel units (21) such as found in subscriber loop carrier (SLC TM ) systems. The circuit is included as part of the remote terminal (20) of the system and performs type tests, power-up tests and routine verification tests. The circuit also monitors the subscriber channel, and connects the subscriber in the event of a ringing signal or an off-hook during a test. The results of the test are sent to a display unit which can be located at the remote terminal and/or the central office.
