OC, OC-n
Optical Carrier — The optical signal that results from an optical conversion of an STS signal; that is,
OC-1 from STS-1 and OC-n from STS-n.
OC3 Optical Interface Circuit Pack
The FT-2000 OC-48 Lightwave System OC3 Optical Interface circuit pack interfaces with one bidi-
rectional OC-3 signal.
OC12 Optical Interface Circuit Pack
The FT-2000 OC-48 Lightwave System OC12 Optical Interface circuit pack interfaces with one bidi-
rectional OC-12 signal.
OC48 RCVR
The FT-2000 OC-48 Lightwave System OC48 Receiver circuit pack interfaces with the incoming
OC-48 high speed line (receive direction).
OC48 REGENR
The FT-2000 OC-48 Lightwave System OC48 Regenerator circuit pack regenerates one OC-48
signal.
OC48 TRMTR
The FT-2000 OC-48 Lightwave System OC48 Transmitter circuit pack interfaces with an outgoing
OC-48 high speed line (transmit direction).
OHCTL (TERM)
The FT-2000 OC-48 Lightwave System Overhead Controller - Terminal circuit pack provides user
access to the OC-48 SONET overhead channels.
OLS
OLS is a standalone optical multiplexing (up to 20 Gb/s per fiber) system. The OLS has its own
telemetry, fault location, and performance monitoring capability.
Operations Interface
Any interface that provides information on the system behavior or control. These include the equip-
ment LEDs, user panel, CIT, office alarms, and all telemetry interfaces.
Operations Interworking
The capability to access, operate, provision, and administer remote systems through CIT access
from any site in a SONET network or from a centralized operations system.
Optical Line Buildout
An equalizer network between the FT-2000 OC-48 Add/Drop-Rings Terminal and the lightguide
cross-connect panel (or equivalent). It guarantees the proper received signal level at OC48 RCVR
circuit pack.
Original Value
The value given to a CIT provisionable parameter at the factory.
Original Value Provisioning
The original values are the values given to CIT provisionable parameters at the factory. At system
startup, the original values are copied and become the current values. These current values can be
changed using local or remote provisioning. The original values can never be changed.
OS
Operations System — A central computer-based system used to provide operations, administra-
tion, and maintenance functions.
