Abstract

A system and method for determining the status of and controlling network devices distributed throughout a communications network. Each network device is provided with a server/interface module containing a device specific application for that particular network device. The device specific application contains a database of status and control information associated with its associated network device. The server interface module generates a web page that contains at least a portion of the database and is connected to the communications network so that a person using a standard internet browser can view and alter the data contained by the database. When changes and upgrades are made to network device, the browser need not be upgraded.

Claims

control means adapted to be operatively connected to the network component to generate control signals for controlling the network component, and

device specific application means comprising

database means for storing status/control data associated with the status information and the control signals, and

generator means adapted to generate browser data that may be interpreted by the browser software, where the browser data incorporates at least some of the status/control data; and

connecting means adapted to connect the device specific application means to the cable television network such that the display data may be displayed and altered using the browser software, the connecting means comprising a modem for converting the browser data into communications data appropriate for transmission by the cable television network.

2. A system as recited in claim 1, in which the cable television network comprises coaxial cable that carries a power signal and a communications signal, where the power signal supplies power to other components distributed throughout the cable television network and the communications signal carries communications data.

3. A system as recited in claim 2, further comprising a tap assembly operatively connected to the coaxial cable of the cable television network and the modem to allow communications data to be transmitted between the cable television network and the modem.

4. A system as recited in claim 3, in which the network component is an uninterruptible power supply, the system further comprising a power inserter operatively connected to the coaxial cable of the cable television network and the uninterruptible power supply to allow power signals generated by the uninterruptible power supply to be transmitted to the cable television network.

5. A system as recited in claim 1, in which the server/interface means further comprises:

at least one outlet port; and

at least one communications subsystem consisting of an ethernet subsystem, a point-to-point subsystem, and a serial line internet protocol subsystem for transferring browser data to the at least one output port.

6. A system as recited in claim 1, further comprising a tap assembly operatively connected between the cable television network and the modem to allow communications data to be transmitted between the cable television network and the modem.

7. A system as recited in claim 1, in which the network component is selected from the group of network components consisting of an uninterruptible power supply, an end of line monitor, a video amplifier, a line extending amplifier, a fiber optic node, and a power node.

8. A system as recited in claim 1, in which the server/interface means further comprises an internet protocol subsystem for converting the status/control data into browser data and the browser data into status/control data.

9. A system as recited in claim 1, in which the server/interface means further comprises at least one of user datagram protocol subsystem and transmission control protocol subsystem for converting the status/control data into browser data and the browser data into status/control data.

10. A system as recited in claim 1, in which the server/interface means further comprises:

at least one outlet port; and

at least one communications subsystem consisting of an ethernet subsystem, a point-to-point subsystem, and a serial line internet protocol subsystem for transferring browser data to the at least one output port.

11. A system as recited in claim 1, in which the device specific application means further comprises a device interface configured to allow the status means to determine status information from the network component and the control means to transmit control signals to the network component.

12. A system as recited in claim 1, in which the server/interface means further comprises a telephony port operatively connected a telephony line, where the telephony port is configured to allow the browser data to be converted into telephony signals appropriate for transmission to the general purpose computer over the telephony line.

13. A network device for use in a cable television network having at least one control location at which is located a general purpose computer that runs industry standard browser software and which is operatively connected to the cable television network, the network device comprising:
