dBm - Decibel referenced to 1 milliwatt. Used in communications
circuits as a measure of signal power. Zero dBm equals one
milliwatt into a specified impedance, often 600 ohms.
dBm0 - noise power in dBm at a point of zero relative transmission
level
dBmC - decibels referred to 1 milliwatt, C-message weighted
DBME - data base management environment
DBMS - database management system
DBOF - defense business operating fund

DCE - data circuit terminating equipment
DCE - Distributed Computing Environment
DCE - (Data Communication Equipment) - In a communications link,
equipment that is part of the network, an access point to the
network, a network node, or point at which a network circuit
terminates. In an RS-232-C connection, the modem is regarded
as DCE and the user device as DTE (data terminal equipment).
When using serial communications such RS-232, V.35, or X.21,
the DCE is the device sending/receiving from the Telco line. ie: a
modem or CSU/DSU. In contrast to DTE.
DCE/TT - (Data Communications Equipment/Transmitter Timing) -
One of three options available in the sync card port configuration
timing parameter.
