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

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
