internetwork.
network directory A file
containing information required
for one node to communicate with
othernodesin 1) an internetwork,
2) an X.25 network, or 3) a
network that contains non-HP
nodes. The active network
directory on a node must be
named NSDIR.NET.SYS.
network interface NI. The
collective software that enables
data communication between a
system and a network. A node
possesses one or more network
interfaces for each of the
networks to which it belongs.
Network interface types are

design, install, configure,
maintain, and if necessary,
change a network.
network map A drawing that
shows the topology of the
network. For networks managed
by theOpenView DTC Manager, a
network map must be created
using the OVDraw capability
provided with the management
software.
Network Services NS. Software
application products that can be
used to access data, initiate
processes, and exchange
information among nodes in the
network. The HP 3000/iX
Network Services include RPM,

network service that transfers
disk files between nodes on a
network.

back-to-back configuration.
NMCONFIG.PUB.SYS The file
that contains all of the network
configuration data for the
HP 3000 Series 900 computer on
which it resides. It includes
information about the DTCs that
can access the system as well as
information about any Network
Service (NS) products running on
the system. This is the only file
name allowed at run-time.
NMDUMP A utility used to
