摘要： An access unit for a local area network with loop topology includes a pair of connectors, a relay circuit, a pair of transformers, a direct current signal extraction circuit, a constant current circuit, a controller, and a coil. With the above arrangement, when a workstation connected to the access unit generates a composite signal having a DC signal, used for driving the relay circuit, superposed onto an AC signal for data transfer, only the DC signal component is extracted by the direct current signal extraction circuit to be inputted into the controller of the access unit. The relay circuit of the access unit is then operated. Thus, the signal outputted from the workstation, the composite signal having the DC signal superposed on the AC signal, is applied to the concentrator, so that the DC signal contained within the composite signal activates the relay contact in the concentrator. The DC signal superposed on the AC signal is outputted from the workstation and accordingly activates both the relay contact in the access unit and the relay contact connected thereto in the concentrator.

摘要： The single port of a concentrator is branched into a plurality of ports by connecting a connector for the former-stage connector to the port of the concentrator and connecting the former-stage connector of the same structure in the other access unit to the connector for the latter-stage circuit to thereby cascade a plurality of access units. The LAN is expanded by connecting the workstation to the port connector of each of the cascaded access units. The thus, connected workstations provide an overlap signal of an AC signal and a DC signal. DC signal extraction circuit in the access unit extracts the DC signal from the overlap signal. A relay drive circuit is operated by the DC signal so that a relay is switched to the port connector side and the circuit is then connected to the workstation.

摘要： A concentrator for a local area network with loop topology uses a connector to which a first workstation is connected and a relay contact for switching between a state in which second and third workstations positioned at both sides of the first workstation are connected to each other and another state in which the first workstation is connected via the connector between the second and the third workstations. The concentrator includes an activation member for activating the relay contact and a pair of condensers to be charged by direct current from the first workstation when the first workstation is connected. The activation member is operated by discharging the direct current. A controller controls the discharging of one of the pair of condensers by detecting the changes in connection conditions of the first workstation.
