Abstract
Hubs 11-14 are circularly connected with each other. The hubs 11 and 12 are supplied with electric power from the power source 1 and the hubs 13 and 14 are supplied with electric power from the power source 2. Each of the terminals 7-10 has two ports each of which is connected to the hub supplied from different power source.
Claims12
A method of connecting a plurality of hubs and a plurality of terminals with lines, each of the terminals comprising a plurality of ports each of which is connected to one of the lines, comprising the steps of:
- connecting one of the ports and one of the hubs with one of the line at each of the terminals;
- connecting another port of the same terminal with another port of the hubs at each of the terminals;
- activating one of the lines connected with each of the terminals;
- circularly connecting the hubs with each other;
- and
- inactivating one of lines between adjoining two hubs.
The method claimed in clam 1, further comprising the step of:
- detecting a fault on the port connected with the line that was activated at the activating step;
- inactivating the port;
- and
- activating another one of the ports of the same terminal.
A network comprising a plurality of hubs and a plurality of terminals, wherein:
- each of the terminals comprises a plurality of ports each of which is connected to different one of the hubs via a line;
- one of the lines connected to one of the terminals is active and the rest of the lines connected to the same terminal is inactive;
- the hubs are circularly connected with each other;
- and
- one of lines between adjoining two of the hubs is inactive.
