Abstract
A Line Card Manager (LCM) architecture for use at an optical switch in an optical communications network. A LCM with a dedicated processor is provided for different line cards at the switch. The LCM includes a first interface, such as a connector to the line card, for receiving monitored parameters from the line card, and a processor that executes software for determining when an event such as a fault should be set, e.g., when a monitored parameter is out of range. The LCM has a second interface to a local area network at the switch for reporting the event to a Node Manager, which manages the LCM. The LCM is preferably a removable plug-in module of the line card to allow easy upgrades and maintenance. The LCM includes generic software for managing different types of line cards.
