Abstract
A method for monitoring a plurality of components associated with a communications network node. A diagnostic service signal is generated at an intra-node component and transmitted along a first optical path to another intra-node component where the presence or absence of the signal is detected. In this manner, optical paths defined between intra-nodal components can be monitored using a diagnostic service signal.
