leased lines so that they are less dependent on the telecommunication
providers and can provide better service to their customers. Among the largest
national and regional ISPs are AT&T WorldNet, IBM Global Network, MCI,
Netcom, UUNet, and PSINet.
ITU-T
The ITU-T (for Telecommunication Standardization Sector of the International
Telecommunications Union) is the primary international body for fostering
cooperative standards for telecommunications equipment and systems. It was
formerly known as the CCITT. It is located in Geneva, Switzerland
IVR
Interactive Voice Response (IVR) is a software application that accepts a
combination of voice telephone input and touch-tone keypad selection and
provides appropriate responses in the form of voice, fax, callback, e-mail and
perhaps other media. IVR is usually part of a larger application that includes
database access. Common IVR applications include: Bank and stock account
balances and transfers.
LAN
A local area network 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). LAN standard defines cable connection and signal
processing on Physical Layer and Data Link Layer.
Link
Network communication channels consisting of sending and receiving devices,
circuits, transmission path. Usually refer to WAN connection. Referred as
Line, or transmission link.
Loopback test
A loopback test is a test in which a signal in sent from a communications
device and returned (looped back) to it as a way to determine whether the
device is working right or as a way to pin down a failing node in a network.
MAC Address
Standardized data link layer address that is required for every port or device
that connects to a LAN. Other devices in the network use these addresses to
locate specific ports in the network and to create and update routing tables
and data structures. MAC addresses are 6 bytes long and are controlled by
the IEEE. Also known as a hardware address, MAC-layer address, and
physical address. Compare with network address.
MAN
A data network designed for a town or city. MANs are considered larger than
LANs but smaller than WANs. Compare with: LAN, WAN.
MGCP
MGCP, also known as H.248 and Megaco, is a standard protocol for handling
the signaling and session management needed during a multimedia
conference. The protocol defines a means of communication between a media
gateway, which converts data from the format required for a circuit-switched
network to that required for a packet-switched network and the media gateway
controller. MGCP can be used to set up, maintain, and terminate calls
between
