Role: After enabling LMP-WDM, use this drop-down list to choose PEER or
OLS.
LMP allows the ONS 15454 SDH to be used between a peer node and an adjacent optical line system (OLS). Choose PEER to use LMP to manage links between two ONS 15454 SDH nodes where the other node is configured as OLS. Choose OLS to use LMP to manage links between two ONS 15454 SDH nodes where the other node is configured as PEER. In most cases, the ONS 15454 SDH will use OLS mode. PEER is mainly used for simulating unavailable PEER equipment during testing.
