Abstract
In a network management system for managing a network unit from an agent, an internal memory is included in the network unit to store current managed data signals while an agent internal memory is included in the agent to transcribe the current managed data signals from the network unit to the agent by a polling processing unit of the agent. The polling processing unit can acquire the current managed data signals from a zone of the internal memory at a time when the network unit is polled by accessing the zone of the internal memory. Alternatively, an alarm data signal which is representative of a detail of a fault is transferred from the network unit to the agent through an interface which is included in each of the network unit and the agent and which is used in common to transmission of managned data signals. Both the interfaces are connected to each other through a transmission path. An alarm signal indicative of occurrence of the fault is transmitted from the network unit to the agent through an interruption line and the common interface which is included in each of the network unit and the agent.
