ITU–T
International Telecommunications Union is an international organization with 150 member
countries founded in 1865 and headquartered in Geneva. The ITU–T is the
Telecommunication Standardization Sector of the ITU, developing standards for
interconnecting Telecommunication equipment across networks.
IVR
Interactive Voice Response is a two-stage incoming call routing method supported by the
Gateway. It enables Direct Inward Dialing to a LAN terminal even when the ISDN lines do
not have multiple numbers allowing direct dialing to an endpoint.
Kbps
Kilo Bits Per Second. One thousand bits per second. Used to define data transfer bit–rates.
L2W-323P Gateway
Translates between H.323 and H.320 protocols allowing the exchange of voice, video and
data between H.323 based conferencing endpoints on IP networks and H.320 compliant
endpoints on circuit switched ISDN networks as well as Voice over IP (VoIP).
LAN
Local Area Network. A network of connected computers covering a small geographic area
such as a building or a campus.
LED
Light Emitting Diode. A display technology that uses a semiconductor diode that emits light
when charged. The Gateway’s LEDs indicate both correct and problematic operation.
Logical port
A number that combined with the IP address provides a unique transport address for a
device or application.
Mbps
Mega Bits Per Second. One million bits per second. Used to define data transfer bit–rates.
MC
Multipoint Controller – a unit that performs control functions for a multipoint
videoconference.
MCU–323
Multipoint Conferencing Unit – a RADVision device that performs the tasks of an MC and
an MP, and has a built–in Gatekeeper unit.
