Abstract
Firmware is installed in a cable modem, enabling detection of the presence or absence of a cable trap in the feed of a customer location. Such a cable modem includes a trap-detection module and a trap-detection object. The trap-detection module is configured to determine whether a signal is present at a cable-television frequency. The trap-detection object is configured to store data as to whether the signal is present and support polling by providing the stored data in response to a received polling command.
Claims20
A cable modem, comprising:
- a memory;
- and
- a processor configured to:
- receive a polling command;
- determine whether a particular frequency is present in a video signal in response to the polling command;
- determine presence of a functional cable trap based on absence of the particular frequency;
- and
- determine presence of a non-functional cable trap based on the presence of the particular frequency.
A method, comprising:
- receiving a polling command;
- determining whether a particular frequency is present in a video signal in response to the polling command;
- determining presence of a functional cable trap based on absence of the particular frequency;
- and
- determining presence of a non-functional cable trap based on the presence of the particular frequency.
A non-transitory tangible computer-readable storage medium having stored thereon computer-executable instructions that, when executed by a computing device, cause the computing device to:
- receive a polling command;
- determine whether a particular frequency is present in a video signal in response to the polling command;
- determine presence of a functional cable trap based on absence of the particular frequency;
- and
- determine presence of a non-functional cable trap based on the presence of the particular frequency.
