Glossary
are among the devices that
communicate serially with
MPE/iX computers.
serial transmission A method
of transferring data in which
characters are transmitted one
bit at a time and received one bit
at a time in the order of
transmission. This transmission
scheme is employed by devices
connected to the MPE/iX systems
via the DTC.
session-accepting device A
terminal or personal computer
running in terminal- emulation
mode that is able to establish an
interactive (conversational)
session with an HP 3000
computer. Also referred to as a
logon device.
shared dial A dial link that
provides connection to more than
one remote system, although to
only one at a time.
shared-line access The feature
that allows two or more HP 3000
Series 900 hosts to use the same
DTC/X.25 Network Access card
on a DTC to access an X.25
network.
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.
SNMP agent A network node,
such as a DTC, that is able to
respond to SNMP requests.
SNMP manager A network
management platform that is
running software which allows it
to manage SNMP nodes.
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 sharedamong several
users by temporarily storing
output data on disk and
managing the selection of output
spool files destined forthe 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.
