Increasing the Channel Capacity of the Node

 

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/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.

Best Practice

Always refer to the PTX3000 Packet Transport Router Hardware Guide when connecting or disconnecting cables on the IPLC modules. See PTX3000 Packet Transport Router Hardware Guide.

To upgrade an IPLC configuration to 64 channels, create a logical association between the IPLC base module and the IPLC expansion module:

  1. From configuration mode, specify the slot location of the IPLC base module and access the IPLC configuration hierarchy.

    For example, if the IPLC base module resides in slot 1:

  2. Specify the slot location of the IPLC expansion module resides.

    For example, if the IPLC expansion module resides in slot 2:

  3. Verify the logical connection between the IPLC base module and expansion module.
  4. If the configuration is correct, save it.
  5. Configure the wavelengths on the IPLC ports, see either Switching a Wavelength to an Optical Interface on a Remote Chassis, Switching a Wavelength to an Optical Interface in the Same Chassis, or Bypassing a Wavelength.
