In telecommunications involving more than one network, it is important to determine the location of a fault which may occur on a connection so that the responsible network administrator can be identified and appropriate remedial measures can be promptly performed. The invention allows sectionalization of trouble on a connection which spans more than one network administrative domain. It uses NE (near-end), FE (far-end) and Int. (intermediate) monitoring signals specific to separate layered entities associated with the connection.
