Proactive Maintenance
Refers to the process of detecting degrading conditions not severe enough to initiate protection
switching or alarming, but indicative of an impending signal fail or signal degrade defect (for
example, performance monitoring).
Protection
Extra capacity (channels, circuit packs) in transmission equipment that is not intended to be
used for service, but rather to serve as backup against equipment failures.
Protection Group
A logical grouping of ports or circuit packs that share a common protection scheme, for
example, UPSR switching, BLSR switching, 1+1 line, or 1+1 equipment.
PROTN
Protection
Provisioning
The modification of certain programmable parameters that define how the node functions with
various installed entities. These modifications are initiated locally or remotely by either a CIT
or an OS. They may arrive at the node via the IAO LAN, CIT port, or any DCC channel. The
provisioned data is maintained in NVM and/or hardware registers.

See Far-End (FE).
Remote Defect Indication (RDI)
An indication returned to a transmitting terminal that the receiving terminal has detected an
incoming section failure. [Previously called far-end-receive failure (FERF).]
Remote Network Element
Any Network Element that is connected to the referenced Network Element through either an
electrical or optical link. It may be the adjacent node on a ring, or N nodes away from the
