Glossary

DSLAM	Digital Subscriber Line Access Multiplexer. A platform for DSL modems that provides
	high-speed data transmission over traditional twisted-pair wiring.
DSR	Data Set Ready. A signal from the modem to the DTE that indicates the modem is turned
	ON and connected to the DTE.
DTE	Data Terminal Equipment. The equipment, such as a computer or terminal, that provides
	data in the form of digital signals for transmission.
DTLB	Data Terminal LoopBack. Loopback mode that loops the data for a particular synchronous
	data port back to the port just before it is combined with the rest of the T1 data stream.
DTR	Data Terminal Ready. A signal from the DTE to the modem, sent via Pin 20 of the
	EIA-232 interface (V.24 circuit 108/1, /2), that indicates the DTE is turned ON and
	connected to the modem.
E1	A wideband digital interface operating at 2.048 Mbps, defined by ITU recommendations
	G.703 and G.704. It is used primarily outside North America.
EER	Excessive Error Rate. An error rate that is greater than the threshold that has been
	configured in the device.
EOC	Embedded Operations Channel. An in-band channel between DSL devices, used for
	8 kbps management data.
ES	Errored Seconds. A second with one or more error events (one or more CRC error events
	or OOFs).
ESF	Extended SuperFrame. The T1 transmission standard that specifies 24 frames as an
	extended superframe to be used for frame synchronization and to locate signaling bits.
Ethernet	A type of network that supports high-speed communication among systems. It is a widely
	implemented standard for LANs. All hosts are connected to a coaxial cable where they
	contend for network access using a Carrier Sense, Multiple Access with Collision
	Detection (CSMA/CD) paradigm.
ETSI	European Telecommunications Standardization Institute. An organization that produces
	technical standards in the area of telecommunications.
factory defaults	A predetermined set of configuration options containing the optimum settings for operation
	on asynchronous dial networks.
FAS	Frame Alignment Signal. A loss of frame (LOF) error detection.
FAW	Frame Alignment Word. A loss of synchronization error detection.
FCC	Federal Communications Commission. The Board of Commissioners that regulates all
	electrical communications that originate in the United States.
FEBE	Far-End Block Error. Block errors reported by remote equipment.
frame relay	A high-speed connection-oriented packet switching WAN protocol using variable-length
	frames.
FTP	File Transfer Protocol. A TCP/IP standard protocol that allows a user on one host to
	access and transfer files to and from another host over a network, provided that the client
	supplies a login identifier and password to the server.
G.703	An ITU recommendation for the physical and logical characteristics of hierarchical digital
	devices.
G.704	An ITU recommendation for synchronous frame structures.
HDB3	High Density Bipolar Three Zeros Substitution. A line coding technique used to
	accommodate the ones density requirements of E1 lines.
