GLOSSARY
Reorder Tone
Atone repeated 120 times a minute; indicates that at least one of the
facilities, such as a trunk or a digit transmitter, required for the call is
not available. Also called Fast Busy Tone.
Single-Line Voice Terminals
Single-line voice terminals served by a Tip Ring Line or Analog Line
circuit pack (2500 series and 7101 A voice terminals or industry
standard Dual-Tone Multifrequency equivalent).
S o f t w a r e
A set of computer programs that accomplishes one or more tasks.
S t a t i o n
A place where terminal equipment is located or sometimes the
terminal equipment itself. Each voice terminal (station) is assigned a
station (extension) number. Users of the terminal are sometimes
referred to as station users.
Reference to the extension number is
sometimes in the form PDC (Personal Dial Code) rather than station
number. PDCs may be “logged in” at other stations. In most
circumstances, PDCs and station numbers may be used
interchangeably. Analogously, data stations are assigned DDCs
(Data Dial Codes).
Station Interconnect Panel (SIP)
The station cross-connect field.
Station Message Detail Recording (SMDR)
Data output by System 25 that provides a record of each incoming
and outgoing call.
Status LED (Lamp)

feature button by the state of the lamp (lighted, flashing, fluttering,
broken flutter, or dark).
