Chapter 8 Transponder and Muxponder Cards

• Link monitoring and management: The cards use standard OC-48 OH bytes to monitor and manage
incoming interfaces. The cards pass the incoming SDH/SONET data stream and its OH bytes
transparently.
• Control of layered SONET/SDH transport overhead: The cards are provisionable to terminate
regenerator section overhead. This is used to eliminate forwarding of unneeded layer overhead. It
can help reduce the number of alarms and help isolate faults in the network.
• Automatic timing source synchronization: The MXP_MR_10DME_C and MXP_MR_10DME_L
cards normally synchronize from the TCC2/TCC2P card. If for some reason, such as maintenance
or upgrade activity, the TCC2/TCC2P is not available, the cards automatically synchronize to one
of the input client interface clocks.
• Configurable squelching policy: The cards can be configured to squelch the client interface output
if there is LOS at the DWDM receiver or if there is a remote fault. In the event of a remote fault, the
card manages MS-AIS insertion.
• The cards are tunable across the full C band (MXP_MR_10DME_C) or full L band
(MXP_MR_10DME_L), thus eliminating the need to use different versions of each card to provide
tunability across specific wavelengths in a band.
• You can provision a string (port name) for each fiber channel/FICON interface on the
MXP_MR_10DME_C and MXP_MR_10DME_L cards, which allows the MDS Fabric Manager to
create a link association between that SAN port and a SAN port on a Cisco MDS 9000 switch.
