Understanding the IPLC Configuration

This topic describes the basic configuration process for the IPLC modules and includes the following sections:

Understanding the Front Panel Connections

The IPLC base module and expansion module are slide-in cards that each occupy a single slot within the PTX3000 chassis. Unlike line cards, the IPLC does not connect into the high-speed data backplane of the chassis, but rather provides the following optical functions that you connect through the front panel:

  • Line IN and Line OUT ports—An input and an output port to connect to the optical line system, such as the optical ILA.

  • PT IN and PT OUT ports—An input and an output port to connect to another IPLC base module. You can use these ports to connect two IPLC base modules together to form a single-node that provides two line-side terminations.

  • XPN IN and XPN OUT ports—An input and an output port to connect to an IPLC expansion module

  • ADD and DROP ports—A total of 32 pairs of ports (32 ADD ports and 32 DROP ports) for 32 DWDM channels

    The IPLC modules are designed to connect the ADD and DROP ports on the front panel to compatible 10-Gigabit or 100-Gigabit DWDM PICs in the same chassis, or to PICs or MICs in a remote chassis.

Slot Placement in the Chassis

Best Practice:

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

The IPLC base module and expansion module each require a single FPC slot. This minimizes slot requirements and ensures that shelf capacity is not sacrificed in single-node east-west or north-south configurations. These slot requirements are especially important if you are configuring a single-node two-line termination that requires 64 channels by using the IPLC expansion modules.

Understanding How to Configure the Add and Drop Ports

The IPLC supports three possible modes of operation for IPLC add and drop ports as follows:

  • blocked—(Default) If there is no explicit configuration for the IPLC wavelength, the wavelength is in blocked mode.

  • switch—Switches the specified IPLC wavelength to an optical interface on the same or different chassis, including a remote chassis.

    To switch a wavelength to an optical interface on the same chassis, enter the following in the CLI:

    To switch a wavelength to an optical interface on a remote chassis, enter the following in the CLI:

  • wss-express-in—Optically bypass the specified wavelength. For example to configure wavelength 1550.12 on the IPLC in slot 1 to be bypassed:

    Configuring a wavelength in express-in mode is a two-step process. First, you must define the association between the two IPLCs and then you specify the wavelength. For example, the following configuration creates the association between the two IPLC modules in slot 1 and slot 6:

    After you create the association between the two IPLCs, you must configure the wavelengths in express-in mode, in either one of the IPLC slots. For example:

    The preceding statements configure wavelength1 and wavelength 2 in express-in mode for IPLCs modules in slot 1 and slot 6.

Frequency, Wavelength, and Port Default Mapping Configuration

All port wavelength frequencies are controlled by the IPLC’s WSS and configured on a wavelength-by-wavelength basis. Table 1 lists the default port, frequency, and wavelength mapping for both of the IPLC modules.
