Answer button
A telephone button with an indicator that is used to monitor another telephone. The
answer button indicates incoming calls destined for the other telephone. Someone
working at a telephone with answer buttons (an attendant, for example) can receive
all ringing and visual indication of incoming calls for other telephones, and answer
those calls when necessary.
One telephone can have up to four Answer buttons. An Answer button is
automatically assigned to a telephone when that telephone is assigned an
Answer DN.
Answer DN
The internal or directory number (DN) of a telephone that is monitored by an
Answer button. You can assign up to four Answer DNs to a telephone under Line
Access in Terminals and Sets programming.
Application Program Interface (API)
An API is the specific method prescribed by an operating system or by another
application program when a programmer writes an application program. The API is
used to make requests of the operating system or another application.
Unlike the graphical user interface or command interface, which are direct user
interfaces, the API is an interface to an operating system or a program.
Application
A computer program that performs a wide range of tasks as specified by the user.
Examples of application programs include word processing packages, spreadsheet
packages and accounting packages.
ARP
See Address Resolution Protocol.
asynchronous
A method of transmission where the time intervals between characters are not
required to be equal and signals are sourced from independent clocks with different
frequencies and phase relationships. Start and stop bits may be added to coordinate
character transfer.
Autobumping
A feature that determines what the system does with new Call Log items when your
Call Log is full. When Autobumping is on, a new log entry causes the oldest entry
to be deleted. If Autobumping is off, your system does not log calls when your log
is full.
