DND
The Do Not Disturb (DND) feature stops calls from ringing at your telephone. Only
Priority Calls will override this feature and ring at your telephone. A line button flashes
when you receive a call, but the call does not ring
telephone to send this signal automatically through a setting in Capabilities. (Services,
Telephony Services, System DNs)
DNs
A unique number that the Business Communications Manager system assigns to every
telephone or data terminal. You use the DN to identify a device for the Business
Communications Manager configurations that require telephone-specific features. The
system also assigns DNs to other applications such as Call Center and Hunt groups. ISDN
and legacy Companion and DECT equipment have separate sets of DNs that are exclusive
to that type of device.
Directory numbers are the digit string that the system uses to identify telephones and
system devices and applications. The DN record provides access to configuring telephone
functionality, including defining the features the user can access, the features the
telephone supports, and the lines that can be used by the telephone to send and receive
calls. See also, DN.
DNS
The domain name system or domain name server (DNS) is the system in the Internet that
maps names of objects, most usually host names, into IP numbers or other resource record
values. The name space of the Internet is divided into domains, and the responsibility for
managing names within each domain is delegated, typically to systems within each
domain.
DNS proxy
A Domain Name Service (DNS) proxy translates alphabetic domain names into
computer-readable IP addresses. For example, the domain name www.nortelnetworks.com
for the Nortel Networks web site can translate to the IP address 192.177.5.18. After a
domain name is translated into an IP address, the workstations on your network can
communicate with the web site. Depending on the configuration of your system, you can
let your workstations know that Business Communications Manager is the DNS proxy.
domain name
The domain name is used to organize Internet names into manageable groups, such as
nortelnetworks.com, where nortelnetworks is the domain name.
