information contained in the configuration
file. The backup file, called
NMCBACK.group.account by default, is
updated each time the configuration file is
successfully validated.
banner A welcome message displayed on
your screen. On the local OpenView
workstation a banner appears when a
remote connection is established with the
OpenView DTC Manager. A banner also
can appear when you log on to MPE.
baud The measure of the speed at which
information travels between devices, most
commonly used in reference to terminal
speed settings. Baud represents signal
events per second. When one bit represents
each signal change, baud is the same as
“bits per second.”
binary mode A data-transfer scheme in
which no special character processing is
performed. All characters are considered to
be data and are passed through with no
control actions being taken.
bit Binary digit. A unit of information that
designates one of two possible states, which
are represented by either 1 or 0.
block mode A terminal processing mode
in which groups, or “blocks,” of data are
transmitted all at once.
BNC T-Connector A connector used to
connect a computer or a component such as
a DTC to the LAN in a ThinLAN
configuration.
boundary See network boundary.
bps Bits per second. The number of bits
passing a point per second.
broadcast Communication method of
sending a message to all devices on a link
simultaneously.
byte A sequence of eight consecutive bits
operated on as a unit.
C
call In X.25, a call is an attempt to set up
communication between two DTEs using a
virtual circuit. Also known as a virtual call.
call collision A conflict that occurs at a
DTE/DCE interface when there is a
simultaneous attempt by the DTE and
DCE to set up a call using the same logical
channel identifier.
called address When a node sends out a
call request packet, the packet contains the
address of the destination node. The
address of the destination node is the
called address.
calling address When a node receives an
incoming call packet, the packet contains
the address of the sending node. The
address of the sending node is the calling
address.
carrier A continuous wave that is
modulated by an information-bearing
signal.
catenet See internetwork.
CCITT Consultative Committee for
International Telephony and Telegraphy.
An international organization of
communication carriers, especially
government telephone monopolies,
responsible for developing
telecommunication standards by making
recommendations. The emphasis is on
“recommendations”; no carrier is required
to adhere to a CCITT recommendation,
although most do so in their own interests.
CIB The channel input/output bus in the
backplane of an HP e3000.
circuit-switching network A type of
data communications network wherein a
