  • Method and apparatus providing out of band validation by content analysis in a cable TV network
    Patent number: 11991414
    Abstract: A method and test instrument for validating one or more out of band (OOB) channels in a CATV network, particularly one having a Remote PHY architecture. The method and test instrument may quickly and efficiently determine if an OOB channel is carrying valid data and is therefore “active.
    Type: Grant

  • UPSTREAM SIGNAL LEAKAGE DETECTION IN HIGH-SPLIT CABLE NETWORK
    Publication number: 20240015088
    Abstract: A CMTS may instruct one or more cable modems to transmit an upstream test signal with a particular preamble (and or any other type of signature) in the upstream transmission bandwidth. The preamble may be within a significant band of the upstream transmission bandwidth. A leakage detection device may be brought in the vicinity of the cable network to listen for various signals. The leakage detection device may filter received signals to retain the portions thereof within a desired limited band and further filter the band-limited signals to reduce noise, e.g., removing the payload following the preamble. A correlation filter in the leakage detection device may compare the pattern in the band-limited filtered signal with a stored preamble. If there is a match, the leakage detection device may generate an indication that leakage is detected in the upstream transmission.
