DTC/X.25 Network Access The
X.25 software that resides on the
Datacommunications and
Terminal Controller (DTC). 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.25
Network Access is configured
through use of the OpenView
DTC Manager software for
systems using PC-based network
managementor throughNMMGR
for systems using host-based
network management.
DTC/X25 Network Access
card This is the hardware card
and channel adapter that
provides X.25 Network Access. It
resides in the
Datacommunications and
Terminal Controller (DTC).
DTC/X25 iX Network Link
Software and hardware that
provides access to private and
public X.25 networks. The X.25 iX
System Access software resides
on an HP 3000 host and is
configured through use of
NMMGR.
DTE Data terminal equipment.
Equipment that converts user
information into
data-transmission signals or
reconverts received data signals
into user information. Data
terminal equipment operates in
conjunction with data
circuit-terminating equipment.
DTS Distributed terminal
subsystem. This consists ofall the
Datacommunications and
Terminal Controllers (DTCs) on a
LAN, their LANIC cards
(attached to the host), the LAN
cable, and the host and DTC
software that controls all related
DTS hardware.
duplex Transmission method
that allows two-way
communication. If both ends of
the transmission link can
transmit simultaneously, it is
called full duplex. If only one end
can transmit at a time, it is
half-duplex transmission.
E
entry priority The ranking that
identifies the most desirable
route used to reach a given
remote node from a given local
node in a point-to-point network.
environment A session that is
established on a remote node.
escape from data transfer
character A character that
allows a user who is connected to
a host system through the DTC to
break that connection and return
to the DTC switching user
interface. The default is
[CTRL]-K.
This character is used only on
networks managed by the
OpenView Windows Workstation
escape sequence A sequence of
characters beginning with the
escape character and followed by
