NAT Network Address Translation: A network capability that enables a
houseful of computers to dynamically share a single incoming IP
address from a dial-up, cable or xDSL connection. NAT takes the
single incoming IP address and creates new IP address for each
client computer on the network.
Numbering plan In a communications network, a numbering plan allocates specific
numeric codes to identify each subscriber line, special lines, trunk
lines, etc. Numbering plans can be divided into the numbering
system and number assignments. The numbering system indicates
the number of digits to be assigned and the basic scheme of number
assignment. The assignment of specific codes is performed
according to the numbering system.
PBX Private Branch Exchange: An in-house telephone switching system
that interconnects telephone extensions to each other as well as to
the outside telephone network.
Peer-to-peer
network A wireless or wired computer network that has no server or central
hub or router. All the networked PCs are equally able to act as a
network server or client, and each client computer can talk to all the
other wireless computers without having to go through an access
point or hub. However, since there is no central base station to
monitor traffic or provide Internet access, the various signals can
collide with each other, reducing overall performance.
POTS Plain Old Telephone Service (POTS), or Pretty Old Telephone
System is the standard analog traditional telephone service that
most homes use. In contrast, telephone services based on high-
speed, digital communications, such as ISDN and DSL, are not
POTS. The main distinctions between POTS and non-POTS
services are speed and bandwidth.
Proxy server Used in larger companies and organizations to improve network
operations and security, a proxy server is able to prevent direct
communication between two or more networks. The proxy server
forwards allowable data requests to remote servers and/or responds
to data requests directly from stored remote server data.
PSTN Public Switched Telephone Network: The worldwide voice telephone
network.
QoS Quality of service (QoS)
RJ-45 Standard connectors used in Ethernet networks. Even though they
look very similar to standard RJ-11 telephone connectors, RJ-45
connectors can have up to eight wires, whereas telephone
connectors have only four.
Router A device that forwards data packets from one local area network
(LAN) or wide area network (WAN) to another. Based on routing
tables and routing protocols, routers can read the network address
in each transmitted frame and make a decision on how to send it via
the most efficient route based on traffic load, line costs, speed, bad
connections, etc.
