Overview

Teaches you how to modify L-Band Add/Drop multiplexer properties. Follow these detailed step-by-step instructions carefully to ensure the specific configuration is applied correctly and securely within your network.

Use this procedure to modify the properties of the Add/Drop multiplexer in a site.

Before you begin

Log in to the Cisco ONP web interface.

Procedure

1.

Open the network where you want to modify the L-band Add/Drop multiplexer properties.
2.

Choose Network > Entity Editor.
3.

In the Entity Editor window, navigate to Sites > Site > Site domain > Side > L-Band.
4.

Click Add/Drop and modify the properties in the next pane. Refer to L-band Add/Drop multiplexer properties for property descriptions.

Colorless Ports

NCS 1010

Enter the number of colorless ports.

0

If you keep the default value, Cisco ONP automatically calculates the number of colorless ports based on the number of circuits you added and colorless add/drop units you have configured.

Note

For the R7.10.1 network, you can assign a maximum of 48 colorless ports. The assigned ports are applicable for a combination of LC and MPO ports.

For the R7.11.1 network, you can assign a maximum of 128 colorless ports.

LC Connector Add/Drop

Colorless Add/Drop

NCS 1010
Note

LC Connector Add/Drop appears for networks from R7.11.1.

Colorless Ports

NCS 1010

Enter the number of colorless ports.

â€â€
Note

For the R7.10.1 network, you can assign a maximum of 48 colorless ports. The assigned ports are applicable for a combination of LC and MPO ports.

For the R7.11.1 network, you can assign a maximum of 128 colorless ports.

Colorless Ports Distribution

NCS 1010

  • Click the field to open the Colorless Ports Distribution pop-up window.

  • Choose the NCS1K14-CCMD-16C for each of the LC ports, A/D 4 to A/D 17.

  • Select the number of ports for each CCMD card, ensuring the total does not exceed 128.

  • Click Submit.

When allocating LC ports, consider these priorities:

  1. Degree connection

  2. Direct LC ports

You can allocate CCMD cards only to LC ports that remain after other allocations.

If the Degree Priority under Site Properties is set to LC Ports, the number of CCMD cards that can be selectd on the line side edges depends on the number of degrees (including omni and line degrees, depending on the scalable degree) and the Direct LC ports.

This is explained in this formula:

Maximum number of CCMDs Allowed = 14 - (scalableUptoDegree - 1) - Direct LC add/drops - Number of Omni Edges

The number of ports that you have selected is displayed in the field.

When the Enable Special Settings under the Network properties is enabled, and if the Colorless Ports Distribution has not been set previously, the property defaults to 16, 16, 0. In this case, three LC ports are already used for CCMD card.

Note

For omnidirectional sides, you can select the CCMD card for every LC port.

After successful analysis of the network, you can view the port distribution under the Layout > Node Diagram tab.

This property is supported only for the enhanced plate.
