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
packetmode 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 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 (residing on the HP 3000
host), and the DTC/X.25 Network
Access. DTC/X.25Network 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
