Glossary
Multipoint Access -
user access in which more than one terminal equipment (TE) is supported
by a single network termination.
Multipoint-to-Multipoint Connection -
a collection of associated ATM VC or VP links, and their
associated endpoint nodes, with the following properties:
1. All N nodes in the connection, called Endpoints, serve as a Root Node in a Point-to-Multi-
point connection to all of the (N-1) remaining endpoints.
2. Each of the endpoints can send information directly to any other endpoint, but the receiv-
ing endpoint cannot distinguish which of the endpoints is sending information without
additional (e.g., higher layer) information.
Multipoint-to-Point Connection -
a Point-to-Multipoint Connection may have zero bandwidth
from the Root Node to the Leaf Nodes, and non-zero return bandwidth from the Leaf Nodes
to the Root Node. Such a connection is also known as a Multipoint-to-Point Connection.
Multiprotocol over ATM (MPOA) -
An effort taking place in the ATM Forum to standardize pro-
tocols for the purpose of running multiple network layer protocols over ATM.
Narrowband Channel -
sub-voicegrade channel with a speed range of 100 to 200 bps.
National TV Standards Committee (NTSC) -
Started in the US in 1953 from a specification laid
down by the National Television Standards Committee. It takes the B-Y and R-Y color differ-
ence signals, attenuates them to I and Q, then modulates them using double-sideband sup-
pressed subcarrier at 3.58MHz. The carrier reference is sent to the receiver as a burst during
the back porch. An industry group that defines how television signals are encoded and trans-
mitted in the US. (See also PAL, SECAM for non-U.S. countries).
Near-End -
in a relationship between two devices in a circuit, the near-end device is the one
that is local.
Network Layer -
Layer three In the OSI model, the layer that is responsible for routing data
across the network.
Network Management Entity (NM) -
body of software in a switching system that provides the
ability to manage the PNNI protocol. NM interacts with the PNNI protocol through the MIB.
Network Management Layer (NML) -
an abstraction of the functions provided by systems which
manage network elements on a collective basis, providing end-to-end network monitoring.
Network Management Station (NMS) -
system responsible for managing a network or portion of
a network by talking to network management agents, which reside in the managed nodes.
Network Module -
ATM port interface cards which may be individually added to or removed
from any ForeRunner ATM switch to provide a diverse choice of connection alternatives.
Network Parameter Control (NPC) -
Defined as the set of actions taken by the network to moni-
tor and control traffic from the NNI. Its main purpose is to protect network resources from
malicious as well as unintentional misbehavior which can affect the QoS of other already
established connections by detecting violations of negotiated parameters and taking appropri-
ate actions. Refer to UPC.
