	Glossary
DEF
Data Conferencing	Enables people in different locations to work
	on the same document via networked
	computers. Also referred to as collaborative
	computing.
DCP	Polycom products equipped with an
	interface that allows direct connection to
	Lucent Definity PBX’s.
	Note This is only applicable to Definity PBXs
	that can be populated with TN2224, TN2214
	or TN2181.
DCP Network Interface Module	The Avaya DCP Module has the same
	network capacity as a Polycom Quad BRI
	network interface module. The chief
	difference is that it connects to an Avaya
	PBX rather than ISDN network interfaces.
DHCP	Dynamic Host Configuration Protocol. DHCP
	servers permit multiple devices to share a
	group of IP addresses, assigning one to a
	specific device as needed.
Digital Line	A telephone line that carries signals in
	discontinuous streams of on and off pulses.
	The audio source must be coded into on and
	off pulses, and decoded into an analog
	signal at the far end destination.
	PBX telephone systems and ISDN are
	examples of systems that use digital
	signaling. PBX and digital Centrex systems
	use proprietary non-standard signaling,
	forcing customers to purchase proprietary
	phones.
