L
line key. A key on the Optiset E telephone that provides access to an extension.
Each line key allows a single telephone call, and a telephone with multiple line
keys allows a user to place multiple simultaneous calls. A user can talk on only
one line at a time, though he or she may have another call waiting on hold on
another line, for example.
M
mute. A feature key that turns the telephone microphone off and on. This
feature controls the microphones in both the handset and the speakerphone.
O
outgoing call. Any call directed outside of your company’s telephone system.
P
PBX (Private Branch Exchange). Equipment that allows an individual
within a community of users to originate and answer calls to and from the
public network, a private network, another PBX, special service trunks, and
other users within that community. The Siemens Communications Server is
part of this generic class of switching systems called PBXs. When not referring
specifically to the communications server, the term “PBX” is used (e.g., other
vendors’ PBXs).
