or data communications equipment (DCE) devices.
CSU/DSU
Channel Service Unit/Data Service Unit. CSUs (channel service units) and DSUs
(data service units) are actually two separate devices, but they are used in
conjunction and often combined into the same box. The devices are part of the
hardware you need to connect computer equipment to digital transmission lines).
The Channel Service Unit device connects with the digital communication line and
provides a termination for the digital signal. The Data Service Unit device,
sometimes called a digital service unit, is the hardware component you need to
transmit digital data over the hardware channel. The device converts signals from
bridges, routers, and multiplexors into the bipolar digital signals used by the digital
lines. Multiplexors mix voice signals and data on the same line.
D
DCE
Data Communications Equipment is typically a modem or other type of
communication device. The DCE sits between the DTE (data terminal equipment)
and a transmission circuit such as a phone line.
DHCP
Dynamic Host Configuration Protocol automatically assigns IP addresses to clients
when they log on. DHCP centralizes IP address management on central computers
that run the DHCP server program. DHCP leases addresses for a period of time
which means that addresses are made available to assign to other systems.
DMT
Discrete Multi-Tone frequency signal modulation
