Media Access Control (MAC) Address
A layer 2 address, 6 bytes long, associated with a particular network device; used to identify devices in a
network; also called hardware or physical address.
Network
A group of computers, terminals, and other devices and the hardware and software that enable them to
exchange data and share resources over short or long distances. A network can consist of any combination
of local area networks (LAN) or wide area networks (WAN).
Private Branch Exchange (PBX)
A small to medium sized telephone system and switch that provides communications between onsite
telephones and exterior communications networks.
Protocol
A formal set of rules developed by international standards bodies, LAN equipment vendors, or groups
governing the format, control, and timing of network communications. A set of conventions dealing with
transmissions between two systems. Typically defines how to implement a group of services in one or two
layers of the OSI reference model. Protocols can describe low-level details of machine-to-machine interfaces
or high-level exchanges between allocation programs.
Public Switched Telephone Network (PSTN)
The local telephone company network that carries voice data over analog telephone lines.
Router
A specialized switching device which allows customers to link different geographically dispersed local area
networks and computer systems. This is achieved even though it encompasses different types of traffic under
different protocols, creating a single, more efficient, enterprise-wide network.
Switched Circuit Network (SCN)
A communication network, such as the public switched telephone network (PSTN), in which any user may be
connected to any other user through the use of message, circuit, or packet switching and control devices.
Server
A computer or device on a network that works in conjunction with a client to perform some operation.
Session Initiation Protocol (SIP)
A protocol for transporting call setup, routing, authentication, and other feature messages to endpoints within
the IP domain, whether those messages originate from outside the IP cloud over SCN resources or within the
cloud.
Subnet
An efficient means of splitting packets into two fields to separate packets for local destinations from packets
for remote destinations in TCP/IP networks.
Transmission Control Protocol/Internet Protocol (TCP/IP)
The basic communication language or protocol of the Internet. It can also be used as a communications
protocol in a private network (either an intranet or an extranet).
Voice Over IP (VoIP)
The technology used to transmit voice conversations over a data network using the Internet Protocol. Such
data network may be the Internet or a corporate Intranet.
