SIC Serial Interface Card. A card installed in the
front of the DTC that acts as an interface between a
corresponding Connector Card (CC) and the DTC’s
processor.
slaved device A device that shares the same DTC
port as another device and is connected, to the other
device, referred to as its master, by a cable. The
actions of the slaved device are controlled by the
master device.
SNMP Simple Network Management Protocol. An
industry standard, for managing networked
computers in a multi-vendor environment.
SNP Synchronous Network Processor card; an
alternative name for an X.25 board.
spooled device A printer that is accessed through
the MPE/iX spooling facility. The spooling facility
allows a nonsharable device to be shared among
several users by temporarily storing output data on
disc and managing the selection of output spool files
destined for the spooled device.
start bit A data bit used to signal the start of a
character being transmitted in an asynchronous
communication mode.
station address A link-level address used by the
IEEE 802.3 protocol that is assigned to every node
on an IEEE 802.3 network.
stop bit A data bit used to signal the end of a
character being transmitted in an asynchronous
communication mode.
store-and-forward A technique in which messages
are passed from one node to another in a network to
reach their destination. Point-to-point networks use
the store-and-forward technique to transmit
messages.
subnet Another name for a network, especially if
the network is part of an internetwork. The word
subnet is also a synonym for intranet.
SVC Switched Virtual Circuit. The path through an
X.25 network that is established at call set-up time.
switching See DTC switching.
Switching User Interface The user interface
available when DTC switching is enabled that
allows terminal users to choose the MPE/iX
computer with which they want to establish a
communication link.
synchronous A mode of operation or transmission
in which a continuous data stream is generated
without intervals between characters. The data
stream is synchronized by clock signals at the
receiver and transmitter. As a result, fast
transmission speeds (above 9600 bps) are attainable.
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.
Telnet 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
