SYSGEN The software program that allows you to
configure the operating system on HP 3000 Series
900 computers.
system configuration The method for telling
MPE/iX which peripheral I/O devices are attached to
the DTC and which parameters are required for
system operation.
T
TCP See Transmission Control Protocol.
telenet A proprietary public data network in the
USA.
Telnet Access Card (TAC) A card that resides in
the DTC 48 and provides protocol conversion
between Telnet and AFCP.
Telnet Express See HP ARPA Telnet Express.
TermDSM Terminal Online Diagnostic System
Manager. A utility that provides diagnostic services
for DTC connections by means of a series of
commands accessible through the SYSDIAG utility.
TermDSM is used only when DTCs are managed by
an MPE/iX host system.
terminal name A character string of up to 16
characters specified in the OpenView DTC Manager
configuration (for networks using OpenView
Network Management) to define a terminal by
name. It can be shared by several terminals (pool
port).
terminal profile A set of configuration
characteristics that can be associated with one or
more terminals through the NMMGR configuration.
Terminal profile specifications include the terminal
type, line speed, device class assignment, and other
values relevant to terminals connected through a
DTC.
terminal type A collection of characteristics that
cause a terminal connected to an MPE/iX system to
act and react in a specified manner. You can
configure a terminal to use one of the
system-supplied terminal types, or you can create
custom terminal types using the Workstation
Configurator.
ThinLAN 3000/iX A LAN that conforms to the
IEEE 802.3 Type 10 BASE 2 standard LAN.
throughput class A value assigned to a given
virtual circuit that defines how many network
resources should be assigned to a given call. It is
determined by the access line speed, packet and
window sizes, and the local network's internal
mechanisms.
throughput class negotiation One of the
Network Subscribed Facilities defined at
subscription time. This allows the user to negotiate
the Throughput Class at call set-up time.
timer (T3) The length of time that a link can
remain in an idle state. After the expiration of the
timer, the link is considered to be in a non-active,
non-operational state and is automatically reset.
The value should be chosen carefully. In particular, it
must be sufficiently greater than the
Retransmission Timer (T1) so that no doubt exists
about the link's state.
topology The physical arrangement of nodes in a
network. Some common topologies are bus, star, and
ring.
Transmission Control Protocol TCP. A network
protocol that establishes and maintains connections
between nodes. TCP regulates the flow of data,
breaks messages into smaller fragments if necessary
(and reassembles the fragments at the destination),
detects errors, and retransmits messages if errors
have been detected.
Transpac The national public PSN of France.
transparent mode A data transfer scheme in
which only a limited number of special characters
retain their meaning and are acted on by the system.
All other characters are considered to be data and
are passed through with no control actions being
taken.
transport, network Software that corresponds to
layers 3 and 4 of the OSI network architecture
model. It sends data out over the communications
link, receives incoming data, and routes incoming or
outgoing data to the appropriate destination node.
TS8 See HP TS8.
TTUTIL Also known as the Workstation
Configurator. A program, TTUTIL.PUB.SYS, on the
HP e3000 that is used to create and modify terminal
and printer type files.
