Paradyne 7112 manual Channel allocation, Community name, Configuration option, Data port, Default

Glossary

channel allocation	Assigning specific DS0 channels in the DSU/CSU to specific interfaces (network, DTE
	Drop/Insert, etc.).
community name	An identification used by SNMP to grant an SNMP server access rights to a MIB.
configuration option	Device software that sets specific operating parameters for the DSU.
CPE	Customer Premises Equipment. Terminating equipment supplied by either the customer or
	some other supplier that is connected to the telecommunications network (e.g., DSUs,
	terminals, phones, routers, modems).
CRC	Cyclic Redundancy Check. A mathematical method of confirming the integrity of received
	digital data.
CSA	Canadian Standards Association.
CSU	Channel Service Unit. The function of the DSU that protects the T1 line from damage and
	regenerates the T1 signal.
CTS	Clear to Send. An EIA-lead standard for V.24 circuit CT 106; an output signal
	(DCE-to-DTE).
data port	The electrical interface between the DSU/CSU and the synchronous data terminal
	equipment.
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 preset value that is assumed to be correct unless changed by the user.
digital signal	A signal composed of discrete elements (zeros and ones) instead of a great multitude of
	analog elements.
DS1/E1 MIB	Defines objects for managing the network and DTE Drop/Insert interfaces on the
	DSU/CSU.
DSR	Data Set Ready. An EIA-lead standard for V.24 circuit CT 107; an output signal
	(DCE-to-DTE).
DSU	Data Service Unit. Data communications equipment that provides an interface between the
	DTE and the digital network.
DS0	Digital Signal Level 0.
DS0 channel	Assigning specific DS0 channels in the DSU/CSU to specific interfaces (network, DTE
allocation	Drop/Insert, etc.).
DTE	Data Terminal Equipment. The equipment, such as computers and printers, that provides
	or creates data.
DTLB	Data Terminal Loopback. Loops the data received from the selected port, for all DS0
	channels allocated to the port, back out the port.
DTR	Data Terminal Ready. An EIA-lead standard for V.24 circuit CT 108; an input signal
	(DTE-to-DCE).
D4	The transmission standard that specifies 12 frames as a superframe that is used for frame
	synchronization and to locate signaling bits.
EER	Excessive Error Rate. An error rate that is greater than the threshold in the DSU/CSU.
