Event
A significant change. Events in controlled network elements include signal failures,
equipment failures, signals exceeding thresholds, and protection switch activity. When an
event occurs in a controlled network element, the controlled network element will
generate an alarm or status message and send it to the Lucent NMS.
Event Management (EM)
Subsystem of the Lucent NMS that processes and logs network event reports.
Externally Timed
An operating condition of a clock in which it is locked to an external reference and uses
time constants that are altered to quickly bring the local oscillator’s frequency into
approximate agreement with the synchronization reference frequency.
Extra Traffic
Unprotected traffic that is carried over the protection channels when that capacity is not
used for the protection of service traffic.

F
Far End Block Error (FEBE)
An indication returned to the transmitting node that an errored block has been detected
at the receiving node. A block is a specified grouping of bits.
Far End Receive Failure (FERF)
An indication returned to a transmitting network element that the receiving network
element has detected an incoming section failure.

Frame Alignment Word
FC

FEP
Front End Processor
Free Running
An operating condition of a network element in which its local oscillator is not locked
to any synchronization reference and uses no storage techniques to sustain its accuracy.
