Software
A set of computer programs that accomplish one or more tasks.
Split
A condition whereby a caller is temporarily separated from a connection with the
attendant. This split condition automatically occurs when the attendant, active on a
call, presses the Start button.
Status LED (lamp)
A green LED or lamp that shows the status of a call appearance or a feature button
by the state of the lamp (lighted, flashing, fluttering, broken flutter, or dark).
Station
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.
Though PDCs may be “logged-in” at other stations, in most
discussions, though, PDCs and station numbers are interchangeable. Analogously,
data stations are assigned DDCs (Data Dial Codes)
Switch
The software-controlled communications processor complex that interprets dialing
pulses/tones/keyboard characters and makes the proper interconnections both within
the system and external to the system.
The switch itself consists of a digital
computer, software, storage device (memory), and associated circuit packs and special
hardware necessary to perform the actual connections.
Switchhook
The button(s) on a voice terminal located under the receiver.

(normally after a power outage).
