IP Telephony

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's Packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network.

Jitter

Jitter is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. As the name suggests, jitter can be thought of as shaky pulses. The deviation can be in terms of amplitude, phase timing, or the width of the signal pulse.

LAN

A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).

MAC address

On a local area network (LAN) or other network, the MAC (Media Access Control) address is your computer's unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you're connected to the Internet from your computer (or host as the Internet protocol thinks of it), a correspondence table relates your IP address to your computer's physical (MAC) address on the LAN.

PSTN

The PSTN (public switched telephone network) refers to the world's collection of interconnected voice-oriented public telephone networks, both commercial and government-owned. It's also referred to as the Plain Old Telephone Service.

UTP

Unshielded twisted pair is the most common kind of copper telephone wiring.

Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company.

VoIP

VoIP (voice over IP - that is, voice delivered using the Internet Protocol) is a term used in IP Telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol(IP). In general, this means sending voice information in digital form in discrete Packet rather than in the traditional circuit-committed protocols of the public switched telephone network.
