The Slot Properties pane displays information about the Cisco ONS 15800 or ONS 15801 slot that is
selected in the NE Explorer tree. Use this properties pane to set performance monitoring thresholds for
the module.
Forward error correction (FEC) wavelength converter modules (WCMs) are used at terminal (transmit
direction) and optical add/drop multiplexing (OADM) sites to retime, reshape, and regenerate SONET
and SDH signals.
A block diagram is shown in the following figure.
