Definition
ATA
Analog Telephone Adapter: Used to connect a standard telephone to a high-
speed modem to facilitate VOIP or fax calls over the Internet.
DHCP
Short for Dynamic Host Configuration Protocol, a protocol for assigning
dynamic IP addresses to devices on a network. With dynamic addressing, a
device can have a different IP address every time it connects to the network.
WAN
Wide Area Network. A computer network that spans a relatively large
geographical area. Typically, a WAN consists of two or more local-area
networks (LANs).
DNS
The Domain Name System is the system that translates Internet domain
names into IP numbers. A "DNS Server" is a server that performs this kind of
translation.
FXO
In telecommunications, a Foreign Exchange Office, or FXO, is a telephone
signaling interface that receives POTS, or "plain old telephone service".
FXS
Foreign Exchange Station is the interface on a VOIP device for connecting
directly to phones, faxes, and CO ports on Gateways or key telephone
systems.
GATEWAY
A network point that acts as an entrance to another network
IP ADDRESS
Every machine that is on a network (a local network, or the network of the
Internet) has a unique IP number [four sets of numbers divided by period
with up to three numbers in each set. (i.e. 192.168.0.100)] - If a machine
does not have an IP address it cannot be on a network.
LAN
Local Area Network: A LAN is a group of computers and associated devices
that share a common communications line or wireless link and typically share
the resources of a single processor or server within a small geographic area
(for example, within an office building).
NETMASK
Used by the TCP/IP protocol to decide how the network is broken up into
sub-networks (ex: 255.255.255.0).
