Analyze in-home issues in the topology
Last Updated: July 07, 2026

The following procedure illustrates how you might use In-Home Issues to locate the source of an alarm. In this example, a fiber node has a widespread Upstream Noise issue. The source turns out to be a faulty cable between a tap and a cable modem.

To analyze potential In-Home Issues
  1. Open the Fiber Node view for the fiber node that has the Upstream Noise issue.
  2. Click the Cable Modems tab.
  3. Select the cable modem that has an orange icon.

    This picture shows a cable modem that has crossed the In-Home Issue threshold. The likelihood of an In-Home Issue is 75%.

    NOTE: Thresholds are set by your ServAssure NXT administrator and may differ by fiber node.
  4. Open Map or Logical view and select Additional Options > In-Home.
    NOTE: Map and Logical views have independent overlays. Overlay selections made in one view will not be displayed in the other view.
  5. Look for the service location that is associated with the selected cable modem.

    This picture shows the selected service location with an orange In-Home icon. The modem at this service location is likely to be the cause of the Upstream Noise issue.

  6. To obtain further corroboration, select either the SC-QAM or OFDMA view and examine additional data, such as Composite Equalization and Echo Response.

    Following this analysis, a field technician finds a chewed cable at the service location.
