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 (@).
download The process of loading
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
NS3000/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).

circuits at speeds of up to
19.2 Kbps.
DTC 16iX HP J2062A product. A
DTC terminal server for HP 3000
systems. It allows up to
16 asynchronous connections to
HP 3000 systems.
DTC 16MX HP J2063A product.
A DTC terminal server for HP
3000 and DTC Telnet systems. It
allows up to 16 asynchronous
connections for the HP 3000
environment and for computer
