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.
