Ctrl branch	Control branch of the DSU/CSU menu tree.
CTS	Clear To Send. A signal indicating that the device is ready for the DTE to transmit data.
	Usually occurs in response to Request To Send (RTS).
Cust1	Customer 1 configuration area. The first of two sets of customer-defined configuration

Cust2	Customer 2 configuration area. The second of two sets of customer-defined configuration
	options.
D4	The transmission standard that specifies 12 frames as a superframe that is used for frame
	synchronization and to locate signaling bits.
daisy chaining	Connecting the COM port of one device to the AUX port of another device to provide SNMP
	connectivity.
data port	The electrical interface between the device 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 Communications Equipment. The equipment that provides the functions required to
	establish, maintain, and end a connection. It also provides the signal conversion required 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 factory-preset value that is assumed to be correct unless changed by the user.
