state transition. In Distributed Systems Management (DSM), a condition that exists when
processes are in transition from one state to another. State transitions for PROCESS
objects include ABORTING, STARTING, STOPPING, and SUSPENDING. This term
may also be referred to as a summary state transition.
Subsystem Control Facility (SCF). A part of DSM, it is used to provide a common,
interactive management interface for configuring, controlling, and collecting information
from HP data communications products.
Subsystem Control Point (SCP). A network management process for receiving and
redistributing the messages that SCF sends to certain data communications
subsystems.
superpath. In Expand, the SUPERPATH modifier enables the multi-CPU path feature. See
also multipacket frame.
SVC. See switched virtual circuit (SVC).
SWAN concentrator. See ServerNet wide area network (SWAN) concentrator.
switched virtual circuit (SVC). A virtual circuit that is dynamically established on demand.

SYSTEM command. A network-related HP Tandem Advanced Command Language (TACL)
command that designates a default system name.
system load. (1) To start the system; to load the operating system image from disk or tape
into the memory of a processor. (2) The process of loading a copy of the operating
system into a halted processor. All processors in a system must be halted before a
system load can occur. (3) The process of loading the operating system. A system load
changes a system from an inactive to an active (or operational) state by loading
software that establishes communications between the operating system and
configured peripherals.
system name. The name assigned to a system. The system name is preceded by a
backslash (\) and can consist of from one to seven alphanumeric characters. The first
character is always alphabetic. Examples of valid system names are \CITY, \SYS43,
and \XYZ.
Systems Network Architecture (SNA). A description of the logical structure, formats,
protocols, and operational sequences for transmitting information units through, and
controlling the configuration and operation of, networks.
TCP. See Transmission Control Protocol (TCP).
TCP port. See port number.
TCP6SAM process. The name of the NonStop TCP/IPv6 access method.
