ONU Details

The ONU details page offers a view of the Optical Network Unit (ONU) hardware level in the hierarchy of your equipment.

Network / Node / Card / OLT / Port / ONU

To access this view, from the left navigation bar select the (Operate) button. A list of all network equipment will populate in a tree view to the left of the map. From the list of equipment that appears, select a ONU in your network by clicking on it. Alternatively, each piece of equipment can be searched for by entering the TID or IP address in the search bar at the top of the list of equipment.

The page will populate with the following information for the node hardware selected:

  • Statistics: Displays detailed statistical information about the fiber connection associated with the selected ONU.

  • Top Insights: Displays alerts (insights) associated with the selected ONU.

  • Admin State: Shows the administrative status of the selected ONU.

  • Oper State: Shows the operational status of the selected ONU.

The content of these tiles is described in detail in the following sections.

Statistics​

The Statistics tile reveals detailed statistical information about the fiber connection associated with the selected ONU. Available statistics are defined in the following table.

Statistic Name     Description

Uptime          The duration since the ONU was discovered. Expressed in seconds.

System Uptime      The duration that the ONT has been powered on.

note

This field only works on SR 11.1.1 or later, and will only display for ONT2-G (GPON ONTs) according to the G.984.4 standard. Otherwise, the GUI will display N/A.

Part Number       The part number associated with the ONU. e.g. 1287787F1

Serial Number        The serial number associated with the ONU. e.g. ADTN20020a66

Downstream BIPs     A counter for incidents of Bit Interleaved Parity (BIP) associated with ingress at the selected ONU.

note

Represents total accumulated since the ONU was discovered.

Upstream BIPs        A counter for incidents of BIP associated with egress at the selected ONU.

note

Represents total accumulated since the ONU was discovered.

OLT Tx Power        The transmit power on the fiber circuit as reported by the OLT. Expressed in dBm.

OLT Rx Power         The receive power on the fiber circuit as reported by the far-end ONU. Expressed in dBm.

ONU Tx Power       The transmit power on the fiber circuit as reported by the ONU. Expressed in dBm.

ONU Rx Power          The receive power on the fiber circuit as reported by the ONU. Expressed in dBm.

Fiber Length          The estimated length of the fiber run from the OLT to the selected ONU. Expressed in meters.

Last Updated           The date and timestamp for when the system last updated insights and statistics.

Top Insights​

The Top Insights tile displays a list of alerts across all network hardware. By default, the Active filter is applied so that all active insights are displayed.

Filters of your choosing can be applied by leveraging the various search fields placed just above the column headers. These search filters may be used individually or in combination to specialize the display to meet your needs.

Access the search field by selecting the adjacent button, then enter the search criteria in the text field that appears.

Top Insights - Table Columns Defined​

Each column of the table of insights displayed on screen is described below.

Severity​

A rating of the severity of the alert rated on a scale of 0-5. The significance of each rating is:

  • Severity 5: Critical
  • Severity 4: Major
  • Severity 3: Minor
  • Severity 3: Minor
  • Severity 2: Alert
  • Severity 1: Informational

System Name​

Top-level name of the network device.

Location​

The identifier of the network location associated with the insight. Exact format of the field will vary depending on the source location.

For example

  • Shelf/slot/port
  • Slot/port
  • RemoteID@Shelf/slot/port

Platform​

Hover over the displayed platform icon to view the platform's family and type. The icon will vary depending on the platform type.

For example

  • Platform Family: Total Access; Platform Type: TA5000
  • Platform Family: SDX; Platform Type: SDX 6320-16

Insight​

A short description of the nature of the alert detected for this row.

See the Operate Detail Views - Insights Glossary for a list of all insight names and detailed descriptions for each.

State​

Insights presented are in one of three states: Active, Cleared, or Acknowledged.

  • Active: An active insight is one that has been detected in the most recent scan.
  • Cleared: Insights shown as cleared were not detected by the most recent scan. The system retains cleared insights for 30 days before automatically removing them from the display.
  • Acknowledged: An acknowledged insight is one that has been manually acknowledged by selecting the insight and selecting the Acknowledge option.

Insight Details Icon​

   Select this icon to reveal the Insight Details dialog. All key facts regarding this insight are displayed in an easy to read layout that includes a suggestion as to how the alert might be resolved.

Select the icon at the top of Insight Details to navigate to the device associated with this insight.

note

An intermittent insight is an insight that has previously been cleared, but has reoccurred.

note

Since MSI allows users to edit the field, the MSI TID could be different than the Operate TID.

Acknowledge / Unacknowledge Buttons​

The button is located just beneath the radio button selector for TID/IP near the top of the Top Insights panel.

To use this feature, choose one or more insight(s) and then select the button to change all selected insights to the Acknowledged state.

The button is located to the right of the Acknowledge button.

To use this feature, choose one or more insight(s) and then select the button to remove the Acknowledged state. This will set insights back to their default state where they display either Active or Cleared.

note

Both Active and Cleared insights may be in the Acknowledged state. If an Acknowledged and Cleared insight becomes Active again (intermittent), the Acknowledged state will only reset and show as Active if the severity increases.

Export Button​

The button is located just beneath the radio button selector for TID/IP near the top of the Top Insights panel.

Use this feature to export this current snapshot of insights to your local drive in CSV format. The exported data can be useful for purposes such as:

  • Sorting the list and delegating portions of it to task various personnel with resolving the alerts.

  • Using it as an offline scratchpad to make notes about your pursuit of the resolution for each alert.

note

The on-screen display is limited to the first 4mb of Top Insights data. When this cap is exceeded, a notification will appear with a reminder that this Export feature can be used to get the complete list of insights in CSV format.

Admin State​

The Admin State panel shows the administrative status of the selected port. The administrative states displayed includes the following:

  • IN-SERVICE

  • OUT OF SERVICE

  • OUT OF SERVICE - MAINTENANCE

  • OUT OF SERVICE - UNASSIGNED

  • UNKNOWN

Oper State​

The Oper State panel shows the operational state of the selected port. The operational states displayed includes the following:

  • UP

  • DOWN

  • DISCOVERING

  • TEST

  • UNKNOWN
