Increasing the Add and Drop Port Capacity of the IPLC Node to 64 Channels

 

The IPLC base module can accept and multiplex (add) and demultiplex (drop) up to 32 individual wavelengths into a single fiber pair. If you require more than 32 channels, you can increase the IPLC node capacity to 64 channels by connecting the IPLC expansion module to the IPLC base module. This procedure describes how to connect these two modules and configure the IPLC node to support 64 channels.

Before you begin, you must physically connect the IPLC base module and expansion module together as follows:

  • Install the IPLC base module and the IPLC expansion module into the PTX3000 chassis.

    Best Practice

    We recommend that you place the IPLC modules into the same FPC or PIC slot pair in the PTX3000 chassis.

  • Connect the two IPLC modules together as follows:

    • Connect the XPN IN port of the IPLC base module to the XPN OUT of the IPLC expansion module.

    • Connect the XPN OUT port of the IPLC base module to the XPN IN of the IPLC expansion module.

This procedure describes how to upgrade an IPLC configuration to 64 channels.

To upgrade an IPLC configuration to 64 channels you must create an association between the between the IPLC base module and the IPLC expansion module:

  1. From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.

    The workspaces that are applicable to Build mode are displayed on the Tasks pane.

  2. From the View selector, select Device View.

    The functionalities that you can configure in this view are displayed.

  3. From the Device View pane, click the plus sign (+) next to the My Network tree to expand the tree and select the PTX300 router for which you want to define the optical IPLC settings.

    The network tree is expanded and the selected device is highlighted.

  4. From the Tasks pane, select Device Management > View Physical Inventory.

    An image of the device is displayed on the right pane.

  5. In the image of the device, select an optical IPLC—for example, an optical IPLC installed in a PTX3000 router.

    The Component Info dialog box is displayed. At the lower part of the dialog box, the Equipment, Status/Config, Performance, and Line Connectivity tabs are displayed.

  6. Click the Status/Config tab at the bottom of the dialog box.

    The IPLC Line dialog box is displayed on the right pane with the configuration settings that pertain to the IPLC.

  7. Specify the FPC or PIC slot in which the IPLC base module resides by selecting the slot in the Chassis View.

    For example, if the IPLC base module resides in slot 1, select the IPLC 1 component in the image of the chassis.

  8. Specify the FPC or PIC slot in which the IPLC expansion module resides.

    For example, if the IPLC expansion module resides in slot 2, select FPC 2 from the Expansion IPLC list in the Settings/Status section.

  9. Configure the wavelength supported by the OTN transponder and make sure it is supported by the IPLC base module.

    For example, to configure the wavelength as 1532.29, select the Show All Wavelengths check box, and select blocked from the drop-down menu in the configuration column of the table for the corresponding wavelength.

  10. Click Update to save the specified configuration settings.
