Abstract

A facility management platform (FMP) monitors and views the status of a plurality of individually addressable downstream devices including, but not limited to, addressable terminals, IRG'"'"'s, settops, cable modems, taps, nodes, and/or hubs at a network control center. The FMP may display problems at these downstream devices, for example, power loss, and/or may automatically notify the appropriate companies and/or personnel to correct the problem.

Claims

1. A facility management platform for providing fault management in a cable network for a plurality of downstream devices located in said cable network, said cable network further having a plurality of low power amplifiers disposed therein, the facility management platform comprising:

a controller;

a display;

said controller for viewing status of said plurality of downstream devices and for determining whether power to said downstream devices has been lost;

said display for displaying a geographic map of said cable network showing said plurality of downstream devices and graphically illustrating when said controller has determined that power to said downstream devices has been lost.

2. The facility management platform of claim 1, wherein said plurality of downstream devices includes at least one of a integrated residential gateway, cable tap, cable node, cable hub, cable settop terminal, and cable modem.

3. The facility management platform of claim 1, wherein said controller for further determining whether said low power amplifier disposed in said cable network has been actuated.

4. The facility management platform of claim 3, wherein said controller for separately addressing said plurality of low power amplifiers to individually test each of said amplifiers.

5. The facility management platform of claim 4, said test for determining whether an actual power loss has occurred at said downstream devices.

6. The facility management platform of claim 1, wherein said controller for automatically notifying one of a power company and maintenance personnel when said controller determines that power to said downstream devices has been lost.

7. The facility management platform of claim 1, wherein said display being a touch screen display for viewing and inputting additional information related to said plurality of downstream devices.

8. The facility management platform of claim 1, wherein said controller:

determining which downstream devices are currently on lifeline support; and

graphically illustrating said downstream devices currently on lifeline support on said display.

9. The facility management platform of claim 1, wherein said controller:

periodically polling said plurality of downstream devices;

determining which downstream devices are currently on lifeline support; and

graphically illustrating said downstream devices currently on lifeline support on said display.

10. A system for fault management and control in a cable network, comprising:

a facility management platform coupled to said cable network;

a plurality of downstream devices disposed in said cable network for providing cable services to subscribers;

a plurality of individually addressable low power amplifiers disposed in said cable network for providing lifeline support;

a cabling facility connecting said facility management platform to said plurality of downstream devices and for providing power and lifeline support to said plurality of downstream devices for servicing said subscribers;

said facility management platform for monitoring said plurality of downstream devices and determining which of said plurality of downstream devices have lost power, appropriately notifying an associated power company and testing said low power amplifiers to isolate problems related to power loss.

11. A method of graphically illustrating status of downstream devices at a facility management platform of a network, said method comprising the steps of:

periodically polling said downstream devices;

determining which of said downstream devices are on lifeline support;

graphically illustrating said downstream devices currently on lifeline support on a display;

notifying an associated power company; and

performing tests to isolate problem s related to power loss.
