NS3000/iX NMMGR Screens Reference Manual - Edition 9 (36922-90040)

301
VPLUS Software used to generate screens
such as those displayed by NMMGR.
V-Series (V.##) CCITT A set of CCITT
recommendations related to data
communication over a voice-grade
telephone network.
VT See virtual terminal.
W
WAN Wide Area Network. A data
communications network of unlimited size,
used for connecting localities, cities, and
countries.
workstation configurator A utility
(TTUTIL) that allows users to create
customized terminal and printer types by
entering data through a series of VPLUS
screens.
X
X.3 Defines the user facilities that should
be internationally available from a packet
assembler/disassembler (PAD) facility,
when this is offered by a public data
network.
X.21 Defines the physical interface
between a DTE and a DCE of a public data
network where the access to the network is
made over synchronous digital lines.
X.25 Defines the interface between a DTE
and a DCE for packet mode operation on a
public data network (PDN).
X.25 address The X.25 address provided
by the network administration if you are
connected to a public data network (PDN).
X.25 address key An X.25 address key is
a label that maps a node’s IP address to its
X.25 address and its associated X.25
parameters. You have a combined
maximum of 1024 X.25 address keys in the
SVC and PVC path tables.
X.25 LUG address X.25 address of a node
belonging to a LUG.
X.25 iX System Access The software that
works in conjunction with the DTC/X.25
Network Access software to provide access
to X.25. The software resides on an
HP e3000 host and is configured through
use of NMMGR. To configure access to an
X.25 network, you must configure two
software components: the X.25 iX System
Access (residing on the HP e3000 host), and
the DTC/X.25 Network Access. DTC/X.25
Network Access is configured through use
of the OpenView DTC Manager software
for systems using PC-based network
management or through NMMGR for
systems using host-based network
management.
X.29 Defines the interface for data
exchange between a packet-mode DTE and
a remote packet assembly/disassembly
(PAD) facility over a packet-switching
network.
XON/XOFF protocol The flow control
used by MPE/iX systems to protect against
data overruns. XON/XOFF protocol is
controlled by the data recipient who sends
an XOFF character (ASCII DC3) to the
sender if it is unable to continue to receive
data. The sender suspends transmission
until it receives an XON character (ASCII
DC1).
X.Series (X.##) CCITT
recommendations A set of
recommendations for data communication
networks governing their services,
facilities, and terminal equipment
operation and interfaces.
