Map view is one of two topology views, along with Logical view. The topology views show the topology of your HFC network and provide information about alarms and issues in a pictorial format. From these views, you can obtain information such as the location of alarms and the number of modems at a service location.

Map view shows where the topology elements are located on a map relative to the houses and other geographical landmarks.

The topology elements are superimposed on a geographical map that shows their location in the real world. This view is useful to locate a particular tap or other topology element geographically to perform tasks such as:

• Locate a pole so that a field technician can make repairs.
• Determine whether a number of taps that are operating deficiently are located near each other.

This picture shows Map view.

The map contains the following controls:

• Show Full Information: Click to display additional information about a piece of topology.
• Fit Selection in Map: Click to center the selection on the map.
• Show Downstream: Click and hold to see arrows on the cable lines that indicate the downstream direction. When you release the button, the arrows are hidden.

  

• Fit All Topology: Click to fit all of the components of the fiber node onto the map.
• Center on Fiber Node : Click to place the fiber node at the center of the map.
• Additional Options : Click to access settings:

  

  NOTE: Map and Logical views have independent overlays. Overlay selections made in one view will not be displayed in the other view.
  • Alarm: Select an Alarm overlay. You can select:
    • Outage: Click to view Outage alarms on the fiber node. For additional information, see View outage alarm severity.
    • Proactive: Click to view Proactive alarms on the fiber node. For additional information, see View proactive alarm severity in the topology.
    • Highest Threshold: Click to view the absolute highest alarm severity as determined across the cable modem, KPIs, and all frequencies.
    • None: Click to view the map showing no overlay of Proactive or Outage alarms. You can view the topology without information about alarms and thresholds to see how the HFC plant is set up. For example, place your cursor over the various components to see whether the tap reported for a particular location contains enough ports. For additional information, see Topology in map and logical views
  • Show Inspection Points: Select to show inspection points for the alarms that are selected in the Alarms view. See Locate outage problem areas or Locate proactive problem areas.
  • Show Legend: Select to show a legend. See Legend.

  • Show In-Home: Select to show In-Home Issues. See Analyze in-home issues.

  • Show Status: Select to view the Status overlay, which shows how well the modems comply with the configured Outage alarm thresholds. For additional information, see View modem status in the topology.

  • Show Empty Service Locations: Select to view service locations that do not contain modems.

  • Show Spectrum Availability: Select to view modems capable of displaying spectrum data. This is an optional, separately licensed feature and will only appear if the user profile is assigned to a group with the Spectrum Analysis permission.
  • Options: Auto-Fit Selections: Select to automatically fit selected items on the screen. When this box is checked, each time you make a new selection, it is centered on the screen.
  • Hide Network Cables: Select to hide or display network cables, shown in gray. This is only available in Map View.
  • Hide /: Remove icons that show no In-Home Issues and Online .
  • RF Stats: Click to open RF Statistics. See RF statistics for proactive issues by frequency.
  • Hide : Click to remove green callouts from the topology, when viewing RF Stats.

The following symbols appear, depending on the data provided by your system.

• Fiber Node
• Splitter
• Tap with 2 ports
• Tap with 4 ports
• Tap with 6 or more ports
• Amplifier. The amplifier might or might not also contain a splitter.
  NOTE: The Amplifier icon is rotated to align with the direction of the power flow.
• AC power inserter. This is where power is inserted into the network. Each power inserter can have one power supply. Its parent can be any element.
• Power supply. Supplies power to one or more amplifiers on the hierarchy. Clicking on a power supply icon highlights the active network elements that are powered by the power supply. A mouse over the power supply shows the address and anything else embedded in the description.
• Service location having no MAC address. Visible only when Show Empty Service Locations is selected.
• Service location having 1 or more MAC addresses. The number shown on the house indicates the number of modems at the service location.
• Cable line, connecting components. The arrows appear, pointing downstream, when you click and hold the Show Downstream button at the upper right of the map.
