Data Service Unit. Data communications equipment that provides an interface
between the DTE and the digital network.
Digital Signal Level 0. A 64 kbps standard signal or channel.
Assigning specific DS0 channels in the E1 DSU/CSU to specific interfaces
(Network, DTE Drop/Insert, etc.).
Defines objects for managing E1 interfaces and supports the network and DTE
Drop/Insert interfaces on the E1 DSU/CSU.
Data Terminal Equipment. The equipment, such as a computer or terminal, that
provides data in the form of digital signals.
The drop/insert interface that is labeled "DTE" on the rear panel of the E1
DSU/CSU.
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. V.24 circuit 108/1, /2.
Embedded Data Link. The 8 kbps in-band performance channel that provides
4 kbps of user bandwidth for the support of an SNMP management link.
Excessive Error Rate. An error rate that is greater than the threshold that has been
configured in the E1 DSU/CSU.
Electronic Industries Association. An organization providing standards for the data
communication industry.
An EIA standard for a high-speed, 25-position, DCE/DTE interface.
MIB objects unique to Paradyne devices.
A trap unique to Paradyne devices.
A discrepancy between a measured or computed value or condition and the true or
specified value or condition.
Errored seconds. Seconds with one or more error events.
Electrostatic discharge. An undesirable discharge of static electricity that can
damage equipment and degrade electrical circuitry.
A wideband digital interface operating at 2.048 Mbps defined by CCITT standards
G.703 and G.704.
Factory configuration area. A configuration option set that is preset at the company
(read-only options).
An uncorrected hardware error.
An accidental condition that causes a functional unit to fail to perform its required
function.
Federal Communications Commission. A board of commissioners that regulates
electrical communication systems that originate in the United States.
Facility Data Link. The selected framing bits in a wide-area link that are used for
control, monitoring, and testing.
Individual DS0 channels that may be sold separately or in groups to provide
bandwidth that is some fraction of the total E1 capability.
One identifiable group of bits that includes a sequence of bits for control,
framing, etc.
