serving capacity
One of the traffic parameters used by the CAC algorithm to determine if the
link of the particular node can accommodate a VCC or a VPC connection
point.
SET alarm
An alarm that is issued when a fault condition is detected. These alarms have
an activeListStatus value of “SET”.
SETS
See synchronous equipment timing source (SETS) (page 131).
setup priority
In PORS networks, setup priority indicates the relative importance of a
connection, and its tolerance of path bumping. A connection with a lower
setup priority can be bumped to an alternative path or terminated by a
connection with a higher priority.
SFP module
See Small form-factor pluggable optical transceiver module (page 123).
SFQ
See shaped fair queuing (SFQ) (page 120).
SFS
See shadowed file system (SFS) (page 120).
shadowed file system (SFS)
A mass storage file system that retains data on the control processor hard
disks. Data retained by the file system includes software, provisioning data,
and spooled data from the data collection system. The shadowed file system
allows up to two disks to operate in synchronization for redundancy.
shaped fair queuing (SFQ)
A method for smoothing out traffic bursts. SFQ is useful for ensuring that
transmitted egress traffic conforms to subscribed traffic parameters. SFQ
regulates the emission interval of cells in the egress direction.
shared buffer memory
See shared memory (page 121).
shared bus
A 32-bit bus on a processor card that ties all peripheral devices together. The
shared buffer memory, shared bus interface controller, link controller, and bus
controller are some of the devices that use the shared bus.
