component instance

When more than one of a component type exists, they are differentiated by an
instance value. The instance value is information (such as a decimal or a
string) appended to the component type.

component model

An OSI-like management model describing Nortel Multiservice Switch nodes
in terms of a set of components arranged into hierarchies. Components
contain attributes that are arranged in attribute groups. Components support
verbs that take options. A verb applied to a component can produce
responses. Components can also produce asynchronous responses, such as
alarms. The component model is supported over the local, Telnet, Ssh, and
FMIP NMIFs. It is indirectly supported within the Multiservice Switch
enterprise SNMP MIB.

component type

The part of the component name that identifies the component being referred
to. For example, FrameRelayUni is the component type of the component
name FrameRelayUni/4.

congestion state

An indication of the degree of congestion of a memory entity such as a queue
or free list. On ATM FPs, there are four congestion states, where 0 is the most
congested and 3 is the least congested. When a memory entity is in
congestion state x, all data of discard priority greater than x is discarded.

congestion control (CC)

ATM mechanisms that detect, prevent, and correct traffic congestion.

conjugate-structure, algebraic-code-excited linear prediction (CS-
ACELP)

An 8 kbit/s compression algorithm used to encode voice data, based on ITU-T
recommendation G.729.

connection

A channel or path between two network entities. The channel or path can be
either physical or virtual. A network entity is any system or subsystem that is
attached to the network medium.

connection address resolution (CAR)

The protocol by which a data network address is resolved into a routable
destination on the network for the purpose of establishing a call connection.
