asynchronous
A method of transmission where the time intervals between characters are not required to
be equal. Signals are sourced from independent clocks with different frequencies and
phase relationships. Start and stop bits may be added to coordinate character transfer.
ATA2
The Analog Terminal Adapter (ATA2) connects analog telecommunication devices, such
as fax machines, answering machines, and single line telephones, to a digital media bay
module on the Business Communications Manager system. Refer to
settings" on page 424.
autobumping
A feature that determines how the system handles new Call Log items when your Call Log
is full. When Autobumping is on, the system deletes the oldest entry when there is a new
log entry. If Autobumping is off, your system does not log calls when your log is full. This
feature is set by the user at the telephone.
auto dial
A memory button that provides one-touch dialing of external or internal numbers or
accesses features. Internal autodial buttons with indicators, display a solid indicator when
that telephone is busy. In BCM 3.5 and newer software, Answer DNs can act as auto dial
buttons for internal telephones.
Auto DN
This is a system directory number that is assigned to auto-answer trunks that are used to
allow remote users to call into the system. On these trunks, the callers do not enter a
password, but directly access the system. From a security perspective, ensure that these
trunks have adequate restrictions (Remote Access Packages) to prevent unauthorized
system usage. See also DISA DN.
auto hold
A feature that automatically places an active call on hold when you select another line to
answer or make a call. This feature can also be activated by the user with FEATURE 73,
if the feature has not been allowed on the telephone record (Capabilities). See also full
autohold (on idle line).
auto log options
A feature that allows you to select the type of calls stored in your Call Log. You can log
calls not answered, calls not answered at this telephone but answered in the system, all
calls answered and not answered at this telephone, or no calls. This option is set under
User Preferences. (Services, Telephony Services, System DNs)
