GL-2 7984-A2-GB20-10 February 1999
Digital Subscriber Line Access Multiplexer. A platform for DSL modems that provides
high-speed data transmission over traditional twisted-pair wiring.
Data Set Ready. A signal from the modem to the DTE that indicates the modem is turned
ON and connected to the DTE.
Data Terminal Equipment. The equipment, such as a computer or terminal, that provides
data in the form of digital signals for transmission.
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.
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.
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.
Excessive Error Rate. An error rate that is greater than the threshold that has been
configured in the device.
Embedded Operations Channel. An in-band channel between DSL devices, used for
8 kbps management data.
Errored Seconds. A second with one or more error events (one or more CRC error events
or OOFs).
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.
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.
European Telecommunications Standardization Institute. An organization that produces
technical standards in the area of telecommunications.
A predetermined set of configuration options containing the optimum settings for operation
on asynchronous dial networks.
Frame Alignment Signal. A loss of frame (LOF) error detection.
Frame Alignment Word. A loss of synchronization error detection.
Federal Communications Commission. The Board of Commissioners that regulates all
electrical communications that originate in the United States.
Far-End Block Error. Block errors reported by remote equipment.
A high-speed connection-oriented packet switching WAN protocol using variable-length
frames.
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.
An ITU recommendation for the physical and logical characteristics of hierarchical digital
devices.
An ITU recommendation for synchronous frame structures.
High Density Bipolar Three Zeros Substitution. A line coding technique used to
accommodate the ones density requirements of E1 lines.
