Network architecture where an optical fiber connects the telephone switch to a street-
side cabinet where the signal is converted to feed the subscriber over a twisted copper
pair.
FTTH (Fiber To The Home)
Network where an optical fiber runs from telephone switch to the subscriber's premises
or home.
G.992.1
ITU recommendation for a physical layer implementation of an Asymmetric Digital
Subscriber Loop (ADSL) line using G.DMT line coding. The data rates from the network
to the modem are up to 8 Mbps and from the modem to the network up to 800 Kbps.
The data rate varies according to the distance from the customer house and the central
office modem. The DSL service provider specifies the type of service being provided.
G.992.2
ITU recommendation for a physical layer implementation of an DSL service (a.k.a.
G.lite). This service can have up to 1.536 Mbps from the network to the modem and 512
Kbps from the modem to the network. The data rate varies according to the distance
from the customer house and the central office modem. The DSL service provider
specifies the type of service being provided.

provider specifies the type of service being provided. Aslo see UADSL.
Gateway
The default Gateway is the designated router attached to the TCP/IP network. It is
responsible for routing data to other networks. The DSL PCI modem allows the user to
configure this on the "Network Properties" screens found on the "DSL Configure" tool.
Gigabits Per Second (Gbps)
A measure of bandwidth capacity or transmission speed. It stands for a billion bits per
second.
Graphical User Interface (GUI)
A program interface that takes advantage of the computer's graphics capabilities to
make the program easier to use.
HDSL (High data rate Digital Subscribe Line)
Modems on either end of one or more twisted pair wires that deliver T1 or E1 speeds.
At present T1 requires two lines and E1 requires three. See SDSL for one line HDSL.
HFC (Hybrid Fiber Coax)
A system (usually CATV) where fiber is run to a distribution point close to the subscriber
