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.
DTC Manager See OpenView DTC Manager.

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 DT CManager
software for systems using PC-based network
management or through NMMGR for systems using
host-based network management.
DTC/X.25 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/X.25 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 Datacommunications and Terminal
Subsystem. This consists of all 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.
DTS restart The startup of the DTS subsystem,
including the release of all TIO-related resources,
using the DTCCNTRL command file.
DTS shutdown The shutdown of the DTS
subsystem, including the release of all TIO-related
resources, using the DTCCNTRL command file.
