Abstract

A programmably configurable computer network, particularly applicable to small network applications such as home networks, includes a plurality of nodes which may be implemented through wall-box sized components. The nodes may be connected through telephone wires and may also offer telephone connectors at each node. The system may be powered by a high frequency power supply which is isolated from the external telephone system using a low pass filter. In this way, the network can be automatically configured to achieve an efficient and specification compliant topology without requiring rewiring of the building.

Claims

1. A node for a computer network comprising:

a housing to mount in a wall opening;

a programmable switch matrix to allow the node to connect to other nodes in a plurality of different ways; and

a memory storing a connection rule that not more than three hops may be coupled to any one node; and

a device to insure that the network is automatically reconfigured if the network does not comply with said rule.

2. The node of claim 1 wherein said switching network is selectively able to allow a node to be connected either as a pass through node or as a non-pass through node.

3. The node of claim 1 wherein said node is connectable by telephone wires to other nodes.

4. The node of claim 3 including a device that produces a high frequency signal and a low pass filter to prevent said high frequency signal from interfering with telephone service.

5. The node of claim 1 including a microcontroller, and a plurality of transceivers, and an uplink pair and a downlink pair, said switching matrix selectively connectable to a plurality of transceivers or an uplink pair and a downlink pair.

6. The node of claim 1 including at least one telephone connector and one network connector.

7. The node of claim 6 wherein each of said connectors is associated with an indicator, said indicator adapted to indicate the current status of said connector.

8. The node of claim 1 wherein if said network connection rule is violated, the node automatically attempts to reconnect said hops so as to satisfy said network connection rule.

9. A node for a computer network comprising:

a housing to mount in a wall opening;

a programmable switching matrix to allow the node to connect to other nodes in a plurality of different ways; and

a memory storing a connection rule with respect to how the nodes may be connected, the node automatically attempting to reconfigure itself if the rule is not satisfied, and if the node is unable to reconfigure itself to comply with the rule, the node automatically generates a notification.

10. The node of claim 9 wherein said rule is a rule that not more than three hops may be coupled to any one node.

11. The node of claim 10 wherein if said network connection rule is violated, the node automatically attempts to reconnect said hops so as to satisfy said network connection rule.

12. A node for a computer network comprising;

a housing to mount in a wall opening;

a programmable switch matrix to allow the node to connect to other nodes in a plurality of different ways; and

a memory stroring a connection rule that not more than three hops may be coupled to any one node, wherein if said network connection rule is violated, the node automatically attempts to reconnect said hops so as to satisfy said network connection rule, and wherein if the node is unable to reconfigure itself to comply with the network connection rule, the node automatically generates a notification.
