Configuring Systems for Terminals, Printers, and Other Serial Devices (32022-90051)
Glossary 271
Glossary
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 available on MPE/iX
systems, TTUTIL.PUB.SYS, that
allows users to create customized
terminal and printer types by
entering data through a series of
VPLUS screens.
X
X.3 The protocol that defines
which user facilities should be
internationally available from a
packet assembler/disassembler
(PAD) when this is offered by a
public data network.
X.21 The protocol that definesthe
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 The protocol that definesthe
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 MPE/ iX access to X.25.
The software resides on an
HP 3000 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 and the DTC/X.25
Network Access (residing on the
Datacommunications and
Terminal Controller and
configured at the OpenView
Windows Workstation). Together,
these two components provide a
network connection on HP 3000
systems to private and public
X.25 packet-switched networks
(PSNs).
X.29 The protocol that definesthe
interface for data exchange
between a packet-mode DTE and
