D.5.8 Slot Properties—RT
TheSlot Properties pane displays information about the Cisco ONS 15808 module that is installed in the
slot selected in the NE Explorer tree. Use this properties pane to change the module performance
monitoring thresholds.
The receiver transponder is used in terminal sites (receive direction) and in OADM sites to retime,
reshape, and regenerate 2.5 Gbps and 10 Gbps low-input signals. Receiver transponders perform 3R
regenerationof optical signals and provide quality parameters based on forward error correction (FEC)
overhead and client signal validation parameters. Receiver transponders perform out-of-band (OOB)
FEC decoding and error correction for transport signals, which are transmitted to SONET- or
SDH-compliant client equipment. The interface complies with Bellcore GR-253 and ITU-T G.957
SONET and SDH physical interface specifications.
A block diagram is shown in the following figure.

For ONS 15808 receiver transponders, the Slot Properties pane displays the following tabs: Module
View, Identification, Quality of Service, Current, Power, Input Power, and Output Power.

D.5.8.1 Module View Tab

The Module View tab displays a graphic of the transponder that is installed in the slot. The number of
critical,major, minor, and warning alarms for the module is displayed under Alarm Status. (Moving the
mouse pointer over the graphic also displays the alarm counts.) The module status is displayed under
