Paradyne 317x E1 manual DS0 channel allocation

ACCULINK 317x E1 DSU/CSU

DSU	Data Service Unit. Data communications equipment that provides an interface
	between the DTE and the digital network.
DS0	Digital Signal Level 0. A 64 kbps standard signal or channel.
DS0 channel allocation	Assigning specific DS0 channels in the E1 DSU/CSU to specific interfaces
	(Network, DTE Drop/Insert, etc.).
DS1/E1 MIB	Defines objects for managing E1 interfaces and supports the network and DTE
	Drop/Insert interfaces on the E1 DSU/CSU.
DTE	Data Terminal Equipment. The equipment, such as a computer or terminal, that
	provides data in the form of digital signals.
DTE Drop/Insert interface	The drop/insert interface that is labeled ªDTEº on the rear panel of the E1
	DSU/CSU.
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 that has been
	configured in the E1 DSU/CSU.
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.
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.
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.
