Method and apparatus for determining conditions for non-terminated service provider network connections

1. A method for determining conditions for non-terminated service provider network connections, the method comprising:

receiving, at a service provider headend, upstream signals from premises;

determining from a portion of the upstream signals, by the service provider headend, an uncorrectable metric based on application of signal correction to the upstream signals, the portion related to an operating frequency range of a networking device and an operating frequency range of Data Over Cable Service Interface Specification (DOCSIS) devices;

determining, by the service provider headend, from the portion of the upstream signals, a correctable metric based on application of signal correction to the upstream signals;

checking, by the service provider headend, whether a determined uncorrectable metric meets an uncorrectable threshold;

checking, by the service provider headend, whether a determined correctable metric is less than a correctable threshold; and

setting, by the service provider headend, an interference alert when the determined uncorrectable metric meets the uncorrectable threshold and the determined correctable metric is less than the correctable threshold for a temporal threshold, the interference alert indicating a non-terminated pathway to the service provider headend from the premises, wherein the non-terminated pathway indicates a presence of a non-terminated device in or at the premises.

2. The method of claim 1 , wherein the signal correction is forward error correction.

3. The method of claim 1 , wherein uncorrectable metric determination further comprises:

counting a number of uncorrectable errors in the portion of the upstream signals; and

determining the uncorrectable metric from the number of uncorrectable errors.

counting a number of correctable errors in the portion of the upstream signals; and

determining the correctable metric from the number of correctable errors.

5. The method of claim 4 , wherein the uncorrectable metric and the correctable metric are each percentages.

polling the portion of the upstream signals at a defined polling interval over a defined time interval; and

determining whether the determined uncorrectable metric meets the uncorrectable threshold and the determined correctable metric is less than a correctable threshold for each polling event.

7. The method of claim 6 , further comprising:

8. The method of claim 7 , wherein the interference alert is at least one of an audio alert or a visual alert.

9. A method for determining non-terminated service provider connections, the method comprising:

receiving, at a headend receiver, upstream communications from premises;

determining from a defined frequency range of the upstream communications, by an analyzer unit, an uncorrectable percentage from error correction processing of the upstream communications, the defined frequency range being related to a Data Over Cable Service Interface Specification (DOCSIS) operating frequency range;

determining from the frequency range of the upstream communications, by the analyzer unit, a correctable percentage from the error correction processing of the upstream communications;

setting, by the analyzer unit, a non-termination alert when the determined uncorrectable percentage meets an uncorrectable threshold and the determined correctable percentage is less than a correctable threshold for a defined number of times over a defined time interval, wherein the non-termination alert indicates a non-terminated pathway to a service provider central office from the premises, the non-terminated pathway indicative of a presence of a non-terminated device in or at the premises; and

providing, by an alert notification unit, the non-termination alert to initiate corrective actions.

10. The method of claim 9 , wherein the error correction is forward error correction.

11. The method of claim 9 , wherein uncorrectable percentage determination further comprises:

counting a number of uncorrectable errors in the defined frequency range of the upstream communications; and

determining the uncorrectable percentage from the number of uncorrectable errors.

counting a number of correctable errors in the defined frequency range of the upstream communications; and

determining the correctable percentage from the number of correctable errors.

13. The method of claim 12 , further comprising:

polling at the defined frequency range of the upstream communications at a defined polling interval;

determining whether the determined uncorrectable percentage meets the uncorrectable threshold and the determined correctable percentage is less than a correctable threshold for each polling event;

incrementing a persistency counter each time the determined uncorrectable percentage meets the uncorrectable threshold and the determined correctable percentage is less than a correctable threshold; and

resetting the persistency counter when the determined uncorrectable percentage is less than the uncorrectable threshold or when the determined correctable percentage is not less than a correctable threshold,

wherein the setting occurs when the persistency counter meets the defined number of times.

14. The method of claim 13 , wherein the interference alert is at least one of an audio alert or a visual alert.

15. A service provider system comprising:

an upstream receiver configured to receive upstream signals from premises; and

a processor in communication with the upstream receiver, the processer configured to:

determine from a portion of the upstream signals an uncorrectable metric based on signal correction processing of the upstream signals, the portion related to an overlap frequency range between a premises networking device and Data Over Cable Service Interface Specification (DOCSIS) devices;

determine from the portion of the upstream signals a correctable metric based on signal correction processing of the upstream signals; and

generate a non-termination alert when the determined uncorrectable metric meets an uncorrectable threshold and the determined correctable metric is less than a correctable threshold for a persistent period of time, wherein the non-termination alert indicates a non-terminated pathway to a service provider central office from the premises when service is provided to the premises from a different service provider central office, the non-terminated pathway indicative of a presence of a non-terminated device in or at the premises.

16. The service provider system of claim 15 , the processor further configured to:

count a number of uncorrectable errors in the portion of the upstream signals;
