instance
Information (such as a decimal or a string) appended to the component type.
When more than one of a component type exists, they are differentiated by an
instance value.
instance type
The data type for a component instance. The null data type is used for non-
replicated components, and the compound data type is used for multi-indexed
components.
instance value
The actual component instance value as permitted by its type.
instantiating
In PORS, the process of laying down the path on the selected route. Once the
route is selected by the route selector and returned to the source endpoint, the
source endpoint starts the procedure of setting up the path.
inter-domain link
A PNNI link that connects two nodes that are in different local rerouting
domains or a link using a non-PNNI signaling interface such as UNI, IISP, and
AINI.
Integrated Alarm Display (IAD)
A Nortel Multiservice Data Manager Advisor tool used to display alarms.
integrated local management interface (ILMI)
A management interface at an ATM interface that consists of a management
information base (MIB) on each side of the UNI and an SNMP-based protocol
for exchanging information in the MIBs across the UNI.
integrated services digital network (ISDN)
A digital technology that provides combined voice and data services. BRI
access to an ISDN switch provides 2B+D (two 64 kbit/s B-channels and one
16 kbit/s D-channel) over an existing copper telephone line.
Out-of-band signaling is sent over the D-channel to request the setup of one
of the B-channels (for high-speed data or voice applications) or of the D-
channel for low-speed data (which can be multiplexed with the signaling and
other low-speed data applications from other terminals on the same loop).
interface management entity (IME)
The ATM interface over which ILMI is operating.
