DSR Data Set Ready. V.24 circuit 107.
DS0 Digital Signal Level 0. A 64 kbps standard signal or channel.
DS0 channel allocation Assigning specific DS0 channels in the E1 NTU to specific interfaces (HDSL
Network, G.703 DTE, etc.).
DS1/E1 MIB Defines objects for managing E1 interfaces and supports the network and G.703
DTE interfaces on the E1 NTU.
DTE Data Terminal Equipment. The equipment, such as a computer or terminal, that
provides data in the form of digital signals.
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. V.24 circuit 108/1, /2.
EDL 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.
EER Excessive Error Rate. An error rate that is greater than the threshold in the E1 NTU.
EIA Electronic Industries Association. An organization providing standards for the data
communication industry.
EIA 530A An EIA standard for a high-speed, 25-position, DCE/DTE interface.
Enterprise MIB MIB objects unique to Paradyne devices.
enterprise-specific trap A trap unique to Paradyne devices.
error A discrepancy between a measured or computed value or condition and the true or
specified value or condition.
ES Errored seconds. Seconds with one or more error events.
ESD Electrostatic discharge. An undesirable discharge of static electricity that can
damage equipment and degrade electrical circuitry.
ETSI European Telecommunications Standardization Institute. An organization that
produces technical standards in the area of telecommunications.
E1 A wideband digital interface operating at 2.048 Mbps defined by CCITT standards
G.703 and G.704.

(read-only options).
failure An uncorrected hardware error.
fault An accidental condition that causes a functional unit to fail to perform its required
function.
FCC Federal Communications Commission. A board of commissioners that regulates
electrical communication systems that originate in the United States.
FDL Facility Data Link. The selected framing bits in a wide-area link that are used for
control, monitoring, and testing.
FEBE Far-End Block Error. Block errors reported by remote equipment.
Fractional E1 Individual DS0 channels that may be sold separately or in groups to provide
bandwidth that is some fraction of the total E1 capability.
frame One identifiable group of bits that includes a sequence of bits for control,
framing, etc.
frame relay A switching interface that is designed to get frames from one part of the network to
another as quickly as possible.
