I
IDNX. Integrated Digital Network Exchange.
IEEE. Institute of Electrical and Electronics Engineers.
impedance. The combined effect of resistance,
inductance, and capacitance on a signal at a given
frequency.
integrated services digital network (ISDN). A digital
end-to-end telecommunication network that supports
multiple services including, but not limited to, voice and
data.
Note: ISDNs are used in public and private network
architectures.
interface. (1) A shared boundary between two
functional units, defined by functional characteristics,
signal characteristics, or other characteristics, as
appropriate. The concept includes the specification of
the connection of two devices having different
functions. (T) (2) Hardware, software, or both, that links
systems, programs, or devices.
Intermediate Session Routing (ISR). A type of
routing function within an APPN network node that
provides session-level flow control and outage reporting
for all sessions that pass through the node but whose
end points are elsewhere.
International Organization for Standardization
(ISO). An organization of national standards bodies
from various countries established to promote
development of standards to facilitate international
exchange of goods and services, and develop
cooperation in intellectual, scientific, technological, and
economic activity.
internet. A collection of networks interconnected by a
set of routers that allow them to function as a single,
large network. See also
Internet.
Internet. A worldwide network connecting users
through autonomous networks in industry, education,
government, and research. The Internet network uses
Internet Protocol (IP). The major Internet services
include electronic mail, FTP, telnet, World Wide Web,
and electronic bulletin boards (Usenet). For network
interconnection and routing, and Transmission Control
Protocol (TCP) for end-to-end control. (A)
Internet Protocol (IP). A connectionless protocol that
routes data through a network or interconnected
networks. IP acts as an intermediary between the
higher protocol layers and the physical network.
However, this protocol does not provide error recovery
and flow control and does not guarantee the reliability of
the physical network.
Internetwork Packet Exchange (IPX). The network
protocol used to connect Novell's servers, or any
workstation or router that implements IPX, with other
workstations. Although similar to the Internet Protocol
(IP), IPX uses different packet formats and terminology.
IP. Internet Protocol.
IPX. Internetwork Packet Exchange.
ISDN. Integrated services digital network.
ISM. IBM Solution Manager.
ISMD. IBM Software Manufacturing and Delivery.
ISO. International Organization for Standardization.
ISR. Intermediate session routing.
ITU-T. International Telecommunication Union -
Telecommunication (replaces CCITT).
K
Kbps. Kilobits per second (1000 bits per second).
kVA. kilovolt amperes.
L
LAN. Local area network.
LAPD. Link access procedure for D-channel.
LCS. Logical channel station.
LED. Light-emitting diode.
LIC. Line interface coupler.
line switching. Synonym for circuit switching.
link. The combination of the link connection (the
transmission medium) and two link stations, one at each
end of the link connection. A link connection can be
shared among multiple links in a multipoint or token-ring
configuration.
Link Address. For a 2216 with an ESCON Channel
Adapter, a port number determined as follows: If one
ESCD is in the communication path, it is the ESCON
Director (ESCD) port number that is attached to the
host. If two ESCDs are in the path, it is the host-side
port number of the ESCD defined with the dynamic
connection. When no ESCD is in the communication
path, this value must be set to X
