Glossary
GL-2 7112-A2-GB20-20 March 1998
Assigning specific DS0 channels in the DSU/CSU to specific interfaces (network, DTE
Drop/Insert, etc.).
An identification used by SNMP to grant an SNMP server access rights to a MIB.
Device software that sets specific operating parameters for the DSU.
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).
Cyclic Redundancy Check. A mathematical method of confirming the integrity of received
digital data.
Canadian Standards Association.
Channel Service Unit. The function of the DSU that protects the T1 line from damage and
regenerates the T1 signal.
Clear to Send. An EIA-lead standard for V.24 circuit CT 106; an output signal
(DCE-to-DTE).
The electrical interface between the DSU/CSU and the synchronous data terminal
equipment.
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.
Data Channel Loopback. Loops the data received from the network interface, for all DS0
channels allocated to the selected port, back to the network.
A preset value that is assumed to be correct unless changed by the user.
A signal composed of discrete elements (zeros and ones) instead of a great multitude of
analog elements.
Defines objects for managing the network and DTE Drop/Insert interfaces on the
DSU/CSU.
Data Set Ready. An EIA-lead standard for V.24 circuit CT 107; an output signal
(DCE-to-DTE).
Data Service Unit. Data communications equipment that provides an interface between the
DTE and the digital network.
Digital Signal Level 0.
Assigning specific DS0 channels in the DSU/CSU to specific interfaces (network, DTE
Drop/Insert, etc.).
Data Terminal Equipment. The equipment, such as computers and printers, that provides
or creates data.
Data Terminal Loopback. Loops the data received from the selected port, for all DS0
channels allocated to the port, back out the port.
Data Terminal Ready. An EIA-lead standard for V.24 circuit CT 108; an input signal
(DTE-to-DCE).
The transmission standard that specifies 12 frames as a superframe that is used for frame
synchronization and to locate signaling bits.
Excessive Error Rate. An error rate that is greater than the threshold in the DSU/CSU.
