Paradyne 336x E1 manual Dsr

ACCULINK 336x E1 NTU

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.
Fact	Factory configuration area. A configuration option set that is preset at the company
	(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.
