List of terms

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.
