eligible telecommunications carrier
A telecommunications carrier is eligible to receive universal service support, if it offers phone service to all customers
throughout a service area without preference, and it advertises the available supported services through the mass media.
Email
Electronic mail. Messages are composed on computers and then sent over a network, in electronic form to other network users.
Ethernet
Baseband LAN specification originated by Xerox and developed jointly by Xerox, Intel, and Digital Equipment Corp. Nodes
on Ethernet networks use CSMA/CD to contend for access to the transmission medium. 10-Mbps Ethernet includes
specifications for many different cable types, including 10Base2, 10Base5, 10BaseF, 10BaseT, and 10Broad36. A newer
standard, Fast Ethernet, calls for data to be carried at 100 Mbps. Ethernet is similar to IEEE 802.3.
exchange access
The offering of access to telephone exchange services or facilities to originate or end telephone toll services.
F
faceplate
The front panel of a plug-in module such as a line card or power supply.
Federal Communications Commission
Government agency that regulates wire, satellite, and over-the-air transmissions.
fiber optic
The rapid transmission of light pulses in a coded digital format through the fiber cable. In a fiber optic transmitter, a light source
such as a laser or light-emitting diode (LED) is connected to the fiber cable. This light source converts an electronic input signal
into a series of light pulses (representing bits) by blinking on and off millions of times per second. This stream of light pulses
is the combination of many lower rate bit streams formed using digital multiplexing techniques. At the other end of the fiber,
fiber optics receivers capture the light pulses for conversion to electrical signals.
fiber optic cable
Cable that consists of several strands of glass-like material capable of transmitting modilated light using a laser, with the
capacity of 600 times that of coaxial cable.
File Transfer Protocol (FTP)
The first and most fundamental way to transfer files to and from remote computer sites. “Anonymous ftp” refers to accessing
public file archives without a password (login=anonymous, password=your email address).
firmware list
The list of available bundled modem firmware images in the modem card image running in a particular modem slot.
