Link monitoring and management: The MXP_MP_10E card uses standard OC-48 OH (overhead)
bytes to monitor and manage incoming interfaces. The card passes the incoming SDH/SONET data
stream and its overhead bytes transparently.
Control of layered SONET/SDH transport overhead: The card is 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_MP_10E normally synchronizes from the
TCC2 card. If for some reason, such as maintenance or upgrade activity, the TCC2 is not available,
the MXP_MP_10E automatically synchronizes to one of the input client interface clocks.
Configurable squelching policy: The card 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 multiplex section alarm indication signal (MS-AIS) insertion.
