network that isestablished 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.

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
