DEFINITY ECS
DEFINITY ECS	DEFINITY Enterprise Communications Server (ECS). The DEFINITY ECS is a
	telecommunications system that routes voice and data information between
	various endpoints, such as telephones, terminals, and computers. It provides
	highly robust networking capabilities and includes an extensive set of standard
	features, such as Attendant Consoles, Voice Processing Interface, Call
	Coverage, DS1/E1 Connectivity, Hospitality Support, Recorded Announcement,
	and Trunk-to-Trunk Transfer. It also allows for the addition of optional features
	and upgrades to the system as business needs change.
Delimited text file	A file containing fields, records, and values that are separated by commas,
	tabs, semicolons, or other characters.
Dial Pad	An Avaya IP Agent dialog box that displays the 12 characters available on a
	telephone.
Dial Number button	A button on the Dial Number toolbar that an agent uses to go off-hook and
	initiate a dial tone or to dial the digits previously entered in the Number text box.
Dial Number toolbar	A toolbar that provides a number text box, access to the phone directory, call
	history, speed dial, and recent calls list. When an agent enters a string (for
	example, lan) followed by Enter, a popup menu displays with a list of the
	directory entries that start with that string. If the first character of the number is
	a letter, the title of the field will be changed from Number to Name.
Dial Plan	The configuration of an Avaya communication server that determines how
	extensions, external telephone numbers, and server features are contacted or
	activated. For example, a dial plan might determine that all internal extensions
	can be reached by dialing a five-digit number. Dial plans are configured through
	an Avaya communication server.

Domain	For Windows networking, a domain is a subnetwork comprised of a group of
	clients and servers under common control.

	example, .com, .org, and .net are domains.
Domain Naming	An Internet mechanism where Uniform Resource Locator (URL) addresses are
System (DNS)	translated to Internet Protocol (IP) addresses. For example, www.avaya.com
	translates to a series of numbers that use the format 123.123.123.123. DNS
	servers can exist inside private networks that are separated from the Internet.
Drop	An agent uses this feature to disconnect from a call and place another call or to
	disconnect the last person added to a conference call.

Exchange (DDE)	exchange of data, information, and commands.

	States.
