Abstract
A system and method for configuring a network element to support protection switching in an optical network are described. The network element can operate according to the SONET, SDH, or both optical transport standards. Each tributary card of the network element has a baseline set of triggering parameters for supporting each protection scheme of both optical transport standards. A baseline parameter set for a given protection scheme has those triggering parameters that are common to SDH and SONET optical transport standards. One or more additional triggering parameters may be needed by a tributary card to complete the implementation of a particular protection scheme. These additional triggering parameters can be sent to the tributary cards, as needed, to supplement the baseline parameter sets.
