322 Glossary
Glossary
dial link A connection made
through public telephone lines.
direct-connect device An
asynchronous device that is
connected directly to a DTC
through an RS-232-C or RS-422
cable, with no intervening
communications equipment. Also
referred to as a “local connection.”
direct connection Aleased line,
private line, or other
non-switched link in a network.
direct dial A dial link through
which only one remote node can
be reached.
direct-path branching The
process of directly accessing any
screen in NMMGR by entering a
path name in the Command: field.
The path name must be preceded
by an at sign (@).
domain name A name
designated for a system in
ARPANET standard format. This
name can be used by other nodes
on the network to access the host
for which it is configured.
download The process ofloading
operating code and configuration
files into the DTC’s memory. The
DTC is downloaded by the
MPE/iX host for LANs using
host-basednetwork management,
and by the PC for DTCs managed
by the OpenView DTC Manager.
driver Software that controls
input/output devices including
NS 3000/iX links.
DTC Datacommunications and
Terminal Controller. The DTC is
a hardware device, configured as
a node on a LAN, that enables
asynchronous devices to access
HP 3000 Series 900 computers.
Terminals can either be directly
connected to the DTC, or they can
be remotely connected through a
Packet Assembler Disassembler
(PAD). The DTC can be
configured with DTC/X.25
Network Access cards and
DTC/X.25 Network Access
software. A DTC/X.25 iX Network
Link consists of two software
modules: the X.25 iX System
Access software (running on the
host) and the DTC/X.25 Network
Access software (running on the
DTC).
DTCCNTRL A command file you
can use to manage DTS
configurations. Using
DTCCNTRL, you can
dynamically implement DTS
changes, automatically add a new
DTC, shutdown/restart DTS, and
manage/dynamically configure
host-based X.25 connections.
DTC identifier An identifier
used only within NMMGR to
define the branch of the
configuration file containing
information about a particular
DTC. The identifier must begin
with a letter and can be up to
eight characters long.
