Manual-In, ACW, or AUX-Work.
STARLAN
Star-Based Local Area Network
Station Message Detail Recording (SMDR)
An obsolete term now called CDR — a switch feature that uses software and hardware to record call data. See
Call Detail Recording (CDR).
standard serial interface (SSI)
A communications protocol developed for use with 500-type business communications terminals (BCTs) and
400-series printers.
status lamp
A green light that shows the status of a call appearance or a feature button by the state of the light (lit, flash-
ing, fluttering, broken flutter, or unlit).
stroke counts

switchhook
The buttons located under the receiver on a voice terminal.
switch-node (SN) carrier
A carrier containing a single switch node, power units, and, optionally, one or two DS1 converter circuit
packs. An SN carrier is located in a center-stage switch.
switch-node (SN) clock
The circuit pack in an SN carrier that provides clock and maintenance alarm functions and environmental
monitors.
switch-node interface (SNI)
The basic building block of a switch node. An SNI circuit pack controls the routing of circuit, packet, and
control messages.
switch-node link (SNL)
The hardware that provides a bridge between two or more switch nodes. The SNL consists of the two SNI cir-
cuit packs residing on the switch nodes and the hardware connecting the SNIs. This hardware can include
lightwave transceivers that convert the SNI’s electrical signals to light signals, the copper wire that connects
the SNIs to the lightwave transceivers, a full-duplex fiber-optic cable, DS1 converter circuit cards and DS1
facilities if a company does not have rights to lay cable, and appropriate connectors.
switch-processing element (SPE)
A complex of circuit packs (processor, memory, disk controller, and bus-interface cards) mounted in a PPN
control carrier. The SPE serves as the control element for that PPN and, optionally, for one or more EPNs.
