DSLAM (Digital Subscriber Line Access Multiplexer)
Specifically, a device which takes a number of DSL subscriber lines and concentrates
these to a single ATM line
DSP (Digital Signal Processor)
A processor which is optimized to efficiently compute mathematical algorithms on a
sequence of numbers. In communications, basic functions such as Fast Fourier
Transforms (FFTs) are common. DSPs are found in a wide variety of electronic products
including computers and cellular telephones.
E1
European basic multiplex rate which packs thirty voice channels into a 256 bit frame
and transmitted at 2.048 Mbps.
Ethernet Connection
A high speed direct connection to a network where an Ethernet NIC is installed so that
the user can access any host connected to the network.
Ethernet over ATM
Ethernet over ATM - It is also known as RFC 1483. It is a transport protocol that creates
a Ethernet link over ATM cells which are carried on the DSL line. Your DSL modem
supports this protocol.
Feeder Network
That part of a public switched network which connects access nodes to the core
network.
FEXT (Far End CrossTalk)
The interference occurring between two signals at the end of the lines remote from the
telphone switch.
Fiber Optic Cable
A transmission medium composed of glass or plastic fibers; pulses of light are emitted
from a laser-type source. Fiber optic cabling is the present cabling of choice for all
interexchange networks, and increasingly for the local exchange loops as well; it is high
security, high bandwidth, and takes little conduit space. Considered the physical
medium of all future, land-based communications.
FTTC (Fiber To the Curb)
A network where an optical fiber runs from telephone switch to a curbside distribution
point close to the subscriber where it is converted to a copper pair.
FTTCab (Fiber To The Cabinet)
