A digital wideband node (DWN) ( 28, 48 ) is coupled to a remote terminal (RT) ( 22, 42 ) that in turn is coupled to a subscriber's telephone line ( 26, 46 ). The DWN ( 28, 48 ) is configured to (1) pass a subscriber's telephone number signal directly to the RT ( 22, 42 ) whereupon a test path ( 25, 45 ) is formed with the subscriber's telephone line ( 26, 46 ), (2) pass POTS test signals directly to the RT ( 22, 42 ) for testing the subscriber's telephone line ( 26, 46 ) via the test path ( 25, 45 ) and (3) process wideband test control signals into wideband test signals which are conveyed to the RT ( 22, 42 ) for wideband testing of the subscriber's telephone line ( 26, 46 ) via the test path ( 25, 45 ).
