ITU-T
Stands for International Telecommunication Union Telecommunication
Standardization Sector. This is an international organization that develops global
standards on communication technologies. ITU-T performs the previous tasks of
CCITT.
IVR
Stands for Interactive Voice Response. IVR refers to a system that provides data in the
form of recorded messages through phone lines as a response to user input in the form
of human voice or mainly DTMF signal processing. Examples are banks that
allow you to check balance by using a phone or automated stock quotations system.
LAN
Stands for Local Area Network. This is a low-error, high-speed data network that
covers relatively small geographical areas of up to several thousand meters. LAN
inter-connects workstations, peripherals, terminals, and other devices in a building or a
geographically limited area. The LAN standard specifies a cable connection and signal
processing method in the physical layer and data link layer of the OSI model.
Reference: MAN, WAN.
Link
This is a network communication channel configured with lines or a transmission path
between the transmitter and receiver and related devices. A link mainly refers to WAN
connections, and is sometimes called a line or a transmission link.
Loopback Test
This test is performed as follows: Transmit a signal or return it to the transmitter at a
location on the communication path. This loopback test is usually performed to test
the availability of network interfaces.
MAC Address
Stands for Media Access Control Address. This is a standard data link layer address
required for any and all ports and devices connected to LAN. Other devices on a
network use this address to locate a specific port within the network and to create or
update a routing table and data structure. A MAC address is 6 bytes long, and is
managed by IEEE. A MAC address is called as a hardware address, a MAC-layer
address, or a physical address. Compare to: Network Address
MAN
Stands for Metropolitan-Area Network. This network covers the entire area of a large
city. The operation area of MAN is geographically larger than that of LAN; however,
is smaller than that of WAN. Compare to: LAN, WAN.
MGCP
MGCP, which is also known as H.248 or Megaco, is a standard protocol required to
operate signals required during a multimedia conference or to manage sessions. This
protocol defines a method of communications between the media gateway that
