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/iX systems (defined by
NMMGR) that the device can access.
PAD profile A terminal or printer profile that
specifies the configuration characteristics for
PAD-connected devices.
PAD support A software module which can be
downloaded to an X.25 board in a DTC. The software
is used to manage connections with remote PAD
devices.
partner gateway half When gateway halves are
used, two gateway halves are required in order to
provide communication between two networks. Each
is the partner of the other.
path name When configuring with NMMGR, you
can type a string in the COMMAND: field on a screen to
branch to another screen. Each screen has a unique
path name that corresponds to its location in the
hierarchy of configuration screens presented by
NMMGR.
PDN Public Data Network. A data communication
network whose services are available to any user
willing to pay for them. Most PDNs use packet
switching techniques.
point-to-point A link that connects either two
nodes in a NS Point-to-Point 3000/iX network or two
gateway halves.
port An outlet through which a device can be
connected to a computer, consisting of a physical
connection point and controlling hardware,
controlling software, and configurable port
characteristics. Ports can be thought of as data paths
through which a device communicates with the
computer.
Precision Architecture The hardware design
structure for the HP 3000 Series 900 computer
family.
printer name A character string of up to 16
characters specified in the DTC Manager
configuration (for networks using OpenView
Network Management) to define a printer by name.
Can be shared by several printers (port pool).
printer profile A set of configuration
characteristics that can be associated with one or
more printers through the NMMGR configuration.
Printer profile specifications include the printer
type, line speed, device class assignment, and other
values relevant to printers connected through a
DTC.
printer type A collection of characteristics that
cause a printer connected to an MPE/iX system to
act and react in a specified manner. You can
configure a printer to use one of the system- supplied
printer types, or you can create custom printer types
using Workstation Configurator.
privileged mode A capability assigned to accounts,
groups, or users allowing unrestricted memory
access, access to privileged CPU instructions, and
the ability to call privileged procedures
probe protocol An HP protocol used by NS 3000/iX
IEEE 802.3 networks to obtain information about
other nodes on the network.
probe proxy server A node on an IEEE 802.3
network that possesses a network directory. A probe
proxy server can provide a node with information
about other nodes on the same or other networks of
an internetwork.
profile A method of grouping device connection
specifications and characteristics so that the set of
characteristics can be easily associated with groups
of like devices. See also printer profile, terminal
profile.
program captive device See programmatic
device.
Programmable Serial Interface PSI. A hardware
card that fits into the backplane of the HP 3000
Series 900 computer. It provides a physical layer
interface for NS Point-to-Point 3000/iX Links.
