QuadroCS (SW Version 3.1.x) 26
I
Integrated Services Digital Network (ISDN) - is a system of digital phone connections which allows voice and data to be transmitted
simultaneously across the world using end-to-end digital connectivity. There are two basic types of ISDN service: Basic Rate Interface (BRI) and
Primary Rate Interface (PRI). BRI is a basic service is intended to meet the needs of most individual users. PRI is intended for users with greater
capacity requirements
Internet Control Message Protocol (ICMP) - a network-layer Internet protocol that reports errors and provides other information relevant to IP
packet processing.
Internet Protocol (IP) - a unique, 32-bit number for a specific TCP/IP host on the Internet, normally printed in decimal form (for example,
128.122.40.227). Part of the TCP/IP family of protocols, it describes the software that tracks the Internet address of nodes, routes outgoing
messages, and recognizes incoming messages.
Internet Service Provider (ISP) - a vendor who provides direct access to the Internet or a company that provides Internet access to other
companies and individuals.
Intrusion Detection System (IDS) - is a firewall, but together with deleting the dangerous packets or packets including intrusion attacks, IDS also
keeps information about dropped packets and the senders responsible for them.
IP address - also known as the Internet Address, is a unique 32-bit identifier for a specific TCP/IP host computer on a network. IP addresses are in
dotted decimal form, such as 192.168.10.26, with each of the four address fields assigned as many as 255 values.
IP address Mask - A range of IP addresses defined so that only machines with IP addresses within the range are allowed access to an internet
service. To mask a portion of the IP address, replace it with the asterisk wild card character (*). For example, 192.44.*.* represents every computer
on the internet with an IP address beginning with 192.44
IP Gatekeeper - defines the policies that govern a multimedia system such as dialing plans, user privileges, bandwidth consumption, and others.
The gatekeeper also provides the means to extract information from such a system for various purposes, e.g., billing information, users that are
logged in, etc. The gatekeeper is also a focal point for the introduction of supplementary services.
IP Gateway - most commonly, a network device that converts voice and fax calls, in real time, between the public switched telephone network
(PSTN) and an IP network. The main IP gateway functions include voice, fax, compression/decompression, packetization, call routing, and control
signaling. Additional features may include interfaces to external controllers, such as gatekeepers or soft-switches, billing systems, and network
management systems.
IP PBX - an enterprise-based IP data network device that switches VoIP telephone traffic.
IP Telephony - a technology that allows voice phone calls to be made over the Internet or other packet networks using a PC via gateways and
standard telephones.
IPSec - is used to provide security for transmission of sensitive information over unprotected networks such as the Internet. IPSec acts at the
network layer, protecting and authenticating IP packets between participating IPSec devices ("peers"), such as Cisco routers.
J
Jitter Buffer - the buffer that collects incoming packets to place them in the right order. If the network has a high delay variation, increasing the Jitter
Buffer can improve the audio quality, but this also increases the delay.
L
LED - Light-Emitting Diode, A semiconductor device that emits visible light when conducting current. Has replaced incandescent lamps as indicators
in most electronic equipment.
Lifeline POTS - a voice telephone line that works even if electricity is cut off at the customer premises, since the line is powered from emergency
backup at the central office. Multiple lifeline POTS lines can be delivered on one copper pair with the use of a digital line powered pair gain system. A
basic telephone service supplying standard single line telephones, telephone lines, and access to the PSTN.
Local Area Network (LAN) - a short distance data communications network (typically within a building or campus) used to link computers and
peripheral devices under some form of standard control.
Login -the procedure of identifying a user with a username and a password to enter into the protected field.
M
Many Extensions Ringing - a Quadro service that allows configuring several users over Quadro to ring simultaneously when a specific call arrives.
Media Access Control (MAC) Address - the address for a device as it is identified at the Media Access Control layer in the network architecture.
Media Access Control (MAC) Layer - is one of two sublayers that make up the Data Link Layer of the
OSI model. The MAC layer is responsible for
moving data
packets to and from one Network Interface Card (NIC) to another across a shared channel.
Media Gateway - a generic class of products grouped under the Media Gateway Control Protocol (MGCP). A major function of the media gateway is
simple IP/TDM conversion under the control of a softswitch.
