utility. TermDSM is used only
when DTCs are managed by a
host system.
terminal name Characterstring
of up to 16 characters specified in
the Openview DTC Manager
configuration (for networks using
OpenView Network
Management) to define a
terminal by name. May 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
system to act and react in a
specified manner. You may
configure a terminal to use one of
the system-supplied terminal
types, or you may create custom
terminal types using the
workstation configurator.
ThinLAN A LAN media that
conforms to the IEEE 802.3
Type 10 BASE 2 standard LAN.
ThinLAN 3000/iX Link
Hardwareandsoftwarenecessary
to create a broadcast network,
which uses the IEEE 802.3 LAN
cable to transmit messages to all
the nodes on the network. The
messages are then accepted only
by the node or nodes to which
they are addressed. Also includes
the ThickLAN and StarLAN 10
options.
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) 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.
token ring A collection of data
communicationsystemssharing a
common cable and
communicating by means of the
IEEE 802.5 protocol. In a token
ring network, access is controlled
by the passing of a token from
node to node. Outgoing messages
are attached to the token and
