SNMP Simple Network Management Protocol. An
industry standard for managing networked
computers in a multi-vendor environment.
SNMP agent A network node, such as a DTC, that
is able to respond to SNMP requests.
SNP Synchronous Network Processor card; an
alternative name for an X.25 board.
spooled device A printer that is accessed through
the spooling facility. The spooling facility allows a
nonsharable device to be shared among several
users by temporarily storing output data on disk and
managing the selection of output spool files destined
for the spooled device.
start bit Data bit used to signal the start of a
character being transmitted in an asynchronous
communication mode.
station address A 12-digit hexadecimal link-level
address used by the IEEE 802.3 protocol. Every node
on an IEEE 802.3 network has its own station
address.
stop bit 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.
subnet mask Grouping of bits that determines
which bits of the IP address will be used to define a
subnetwork. The subnet mask is configured using
the NMMGR utility and specified in the same format
as an IP address.
SVC Switched Virtual Circuit. Path through an X.25
network that is established at call set-up time.
switching See DTC switching.
Switching user interface User interface available
when DTC switching is enabled that allows terminal
users to choose the HP 3000 Series 900 computer
with which they want to establish a communication
link.
synchronous A mode of operation or transmission
whereby 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 way you tell the
operating system what peripheral I/O devices are
attached and what parameters are required for
system operation.
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 support
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
a host system.
terminal name 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. 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.
