A set of SNA components that provide services that manage and monitor the resources of a node. Each node, whether a control unit, terminal, controller, or processor, contains one physical unit.
In SNA, one of three types of network addressable units. A physical unit exists in each node of an SNA network to manage and monitor the resources (such as attached links and adjacent link stations) of a node, as requested by a system services control point logical unit (SSCP-LU) session.
The natural unit of measurement of the original analog signal (e.g., millivolts, liters per second, degrees). To convert samples into physical units, subtract the ADC zero and divide the remainder by the gain.
An SNA term used to refer to different types of hardware in the network.
The software and hardware of an SNA node that controls the resources of the node and reports errors and physical failures to the SSCP. There is one PU per node.
An IBM Systems Network Architecture component that monitors and manages the resources of a network node as requested by the systems services control point.
The component that manages and monitors the resources (such as attached links and adjacent link stations) of a node, as requested by an SSCP via an SSCP-PU session. Each node of an SNA network contains a physical unit.
The component that manages and monitors the resources (such as attached links and adjacent link stations) associated with a node, as requested by an SSCP via an SSCP-PU session. An SSCP activates a session with the physical unit in order to indirectly manage, through the PU, resources of the node such as attached links. This term applies to type 2.0, type 4, and type 5 nodes only.
In SNA terminology, one remote hardware unit. A PU is distinguished from a logical unit ( LU) because some PUs can embody multiple LUs.
A component of an SNA (Systems Network Architecture) node that controls the resources of the node and reports errors. The access method in the node.
