configuration option	Device firmware that establishes specific operating parameters for the device.
	Sometimes referred to as straps.
CPU fail	Central Processing Unit failure. A Self-Test Health message indicating a failure in
	the device's central processing unit.
CRC	Cyclic Redundancy Check. A mathematical method of confirming the integrity of
	received digital data.
CRC6	CRC using six check bits.
CSA	Canadian Standards Association.
CSU	Channel Service Unit. Protects the T1 line from damage and regenerates the T1
	signal.
Ctrl branch	Control branch of the DSU/CSU menu tree.
CTS	Clear-to-Send. V.24 circuit 106.
Cust1	Customer 1 configuration area. The first of two sets of customer-defined
	configuration options.
Cust2	Customer 2 configuration area. The second of two sets of customer-defined
	configuration options.
daisy chaining	Connecting the COM port of one DSU/CSU to the AUX port of another DSU/CSU
	to provide SNMP connectivity.
data port	The electrical interface between the DSU/CSU and the synchronous data terminal
	equipment.
database	An organized compilation of computerized data.
DB15 connector	A 15-position connector used on cables or devices.
DB25 connector	A 25-position connector used on cables or devices.
DCE	Data Circuit-terminating Equipment or Data Communications Equipment. A device
	which provides signal conversion for communication between the DTE and the
	network.
DCLB	Data Channel Loopback. Loops the data received from the network interface, for all
	DS0 channels allocated to the selected port, back to the network.
default	A preset value that is assumed to be correct unless changed by the user.
DevFail	Device Failure. A message that indicates that an internal failure has been detected
	by the operating firmware. An 8-digit code appears for use by service personnel.
DevHS branch	Device Health and Status branch of the DSU/CSU menu tree.
device	A mechanical, electrical, or electronic unit with a special purpose.
digital signal	A signal composed of discrete elements (zeros and ones) instead of a great
	multitude of analog elements.
diskette	A thin, flexible magnetic disk enclose in a protective jacket.
DL branch	Download branch of the DSU/CSU menu tree.
DLB	DTE Loopback. Loops the received signal on the DTE Drop/Insert port back to the
	DTE without change.
download	A process that transfers device firmware from a locally-attached PC to a device, or
