Viewing Real-time Optical Service PMs

 

Use this procedure to enable and view real-time PMs for optical services on BTI7000 Series and BTI7800 Series network elements. The PMs are displayed in both textual and graphical formats.

PSM supports the following BTI7000 Series optical service PMs:

  1. To enable real-time PMs, right-click on an optical service in the tree view or in the background of an optical service topology view, and choose one of the following:
    • Enable Realtime PMs>Port

    • Enable Realtime PMs>OMS for BTI7800 Series

    • Enable Realtime PMs>OSC

    • Enable Realtime PMs>Service Channel

    • Enable Realtime PMs>All Channels

    Real-time PM collection for the optical service is started, and a PM data widget title bar is displayed for each PM collection point. Additionally, a graphical view displaying the instantaneous power along with the detected power range is provided at the bottom of the screen.

    Note

    When you enable PMs on a stranded service1, you might see PM data widgets that do not have lines connecting them to the network elements. This behavior is normal.

    Note

    1A service is stranded if one or more segments in the path between the service endpoints has not been configured.

  2. Click the PM data widget title bar to show or hide the PM data.

    Note

    The information displayed on the domain (horizontal) axis of the real-time PMs all channels graph is selectable. See Setting optical graphing options for details on how to select what is shown.

  4. To change the range (vertical) scale of the graphs, highlight the desired area by left-clicking and dragging the mouse to highlight the area of focus, and release.

    Repeat until the desired magnification is achieved.

    Note

    You can also change the scale by right-clicking on a graph, and selecting Zoom In or Zoom Out.

  5. To turn off real-time PMs, right-click in the optical services topology window and choose Disable Realtime PMs.
