interpersonal notification (IPN)
interpersonal notification (IPN). See IPN.
IPM (interpersonal message, interim product modification). A type of message
comparable to a business memo. It consists of a heading and one or more body parts.
The heading identifies the body parts, which contain the information.
Alternatively, a slightly modified version of a software product, made available to
customers between regular releases.
IPN (interpersonal notification). A type of message comparable to an acknowledgment of
receipt of a business memo.
ISO (International Organization for Standardization). A United Nations organization,
established to promote the development of standards to facilitate the international
exchange of goods and services and to develop mutual cooperation in areas of
intellectual, scientific, technological, and economic activity.
ISO Reference Model for Open Systems Interconnection. See OSI Reference Model.
ISV (installation subvolume). A subvolume produced from the SUT during the Install
process. The Install process creates many ISVs. The ISV named ZOSIMHS contains
all of the OSI/MHS object files (MTA, RTS, SC, MS, RS, GI, LO, and MHSMGR),
softdocs, and installation macros.
LAN. A local area network. See also TLAM.
layer. A grouping of related functions in the OSI Reference Model. See Application Layer,
Data Link Layer, Network Layer, Physical Layer, Presentation Layer, Session Layer, or
Transport Layer.
link. A physical and logical path between two adjacent computers or other devices.
In OSI/MHS, a pair of OSI addresses that are configured for each MTA. A pair of OSI
addresses is a set of local and remote address definitions in the MTA object representing
an adjacent MTA.
link retry. The action taken when a line to an adjacent MTA fails or is unavailable. All other
links to that MTA are tried. You set the time available to establish the association
through the CLASS attribute LINK-RETRY-TIME. You set the time to wait before an
MR group can retry the previously failed association through the CLASS attribute
LINK-RETRY-DELAY.
LO (local operations) class. The OSI/MHS CLASS object that identifies the set of all LO
groups in a Compaq OSI/MHS subsystem.
LO (local operations) group. The OSI/MHS group that implements the local operations
function, giving local user agents access to an X.400 network through a message store.
The LO group consists of a single LO process and a PDU store. There can be zero, one,
or more LO groups in a single OSI/MHS subsystem. There must be at least one LO
group for the P7 API to connect with OSI/MHS.
