NS 3000/XL A Hewlett-Packard
data communication product that
provides networking capabilities
for MPE XL based HP 3000
minicomputers. NS 3000/XL
consists of a link and network
services.
NS 3000/XL Link Software and
hardware that provides the
connection between nodes on a
network. Some of the NS 3000/XL
links available are the ThinLAN
3000/XL Link and its ThickLAN
option, the DTC/X.25 XL Network
Link, the NS Point-to-Point
3000/XL Link, and the StarLAN
10 3000/XL link.
NS 3000/XL Network Services
Software applications that can be
used to access data, initiate
processes, and exchange
information among nodes in a
network. The services are RPM,
VT, RFA, RDBA, and NFT.
NSDIR.NET.SYS Name of the
active network directory file. See
also network directory.
O
octet An eight-bit byte operated
upon as an entity.
OSI model Open Systems
Interconnectionmodel. Amodelof
network architecture devised by
the International Standards
Organization (ISO). The OSI
model defines seven layers of a
network architecture, with each
layer performing specified
functions.
P
packet A block of data whose
maximum length is fixed. The
unit of information exchanged by
X.25 at Level 3. There are DATA
packets and various control
packets. A packet type is
identified by the encoding of its
header.
Packet Exchange Protocol
PXP. A transport layer protocol
used in NS3000/XL links to
initially establish communication
between nodes when NetIPC
socket registry is used.
packet-switched network
name The name of a data
communication network adhering
to the CCITT X.25
recommendation. This can be a
PDN or a private network, such
as the HP PPN.
PAD (packet
assembler/disassembler) A
device that converts
asynchronous character streams
into packets that can be
transmitted over a packet
switching network (PSN).
PAD name A name of up to eight
characters that is associated with
a configured PAD device. The
PAD name is known to both the
DTC (defined by the DTC
Manager) and the MPE XL
systems (defined by NMMGR)
that the device can access.
