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
