access codes
A digit or group of digits that provide direction to the system as to how to route a call or
access a feature, such as call park. The Access Codes heading also provides access to the
line pool codes and carrier codes. (Services, Telephony Services, General Settings,
Access Codes). Destination codes are a form of access codes for routing services
(Services, Telephony Services, Call Routing). Refer to
“Determining line access dialing”
on page 319 .
Address Resolution Protocol (ARP)
ARP is a protocol for mapping an IP address to a physical machine address that is
recognized in the local network. The physical machine address is also known as a Media
Access Control or MAC address. A table, usually called the ARP cache, is used to
maintain a correlation between each MAC address and its corresponding IP address.
ARP provides the protocol rules for making this correlation and providing address
conversion in both directions.
As an example, this protocol is used when the Business Communications Manager maps
an IP address to an IP telephone.
alarm code
A number that appears on an alarm telephone display when the system detects a fault.
ANSI
American National Standards Institute. This is the ISDN protocol define by the institute
for telecommunications standards within North America. See also ETSI.
answer DNs
This telephone button allows you to monitor activity that occurs on another telephone in
the system by indicating incoming calls to the other telephone. For instance, an attendant
with a telephone with answer buttons can see which telephones on the system are ringing,
and can answer the incoming call, if necessary.
One telephone can have up to eight Answer DNs. When you assign an Answer DN to a
telephone, the system connects that DN to a button with an indicator on that telephone.
There are three answer key levels, which determine which calls appear on the answer
button. This is a system setting. Some features, such as overflow routing, require specific
levels before they can occur.
In BCM 3.5 and newer software, an Answer DN for a internal telephone can also act as a
autodial button to that telephone. The Answer DN telephone must be idle for this type of
call.
Application Program Interface (API)
An API is an interface used by an application 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.
