Use this reference to understand the NCS 1010 multi-degree topology that you model in Cisco Optical Network Planner.
Plan an NCS 1010-based network using Cisco Optical Network Planner to design a topology with the required specifications, analyze it, and generate planning data. For detailed instructions, see Design and Analyze Networks.
This reference network topology illustrates the NCS 1010 bring-up scenarios.
It is a multi-degree topology that uses 13 NCS 1010 nodes in 9 sites, including two three-degree sites: Novara and Brescia.
The BRK-8 modules create express interconnect in Site-Novara and Site-Brescia with OLT-C by using MPO cables. With E-OLT-C/R, the BRK-8 interconnect is not required.
Multi-degree topology
This figure shows the multi-degree topology that uses 13 NCS 1010 nodes in 9 sites, including the Novara and Brescia three-degree sites.

Design the topology in Cisco Optical Network Planner
Use this procedure to create a Cisco Optical Network Planner model that matches the physical design for a new region or pilot network.
The output is a topology file that you can use for Cisco Optical Site Manager exports and downstream bill of materials validation.
The sample node names (Genova, Novara, Brescia, Venezia, Torino, Como, Bergamo, Cremona, and Padova) correspond to the reference network and should be adapted as necessary.
Consider these inputs before you create the network plan. Apply them according to your network design requirements.
Create the number of circuits based on the channel plan and use the appropriate card type for each circuit.
Force the add/drop type according to the design requirements. For details about add/drop configuration, see Modify Network Properties.
Before you begin
Confirm licensing for Cisco Optical Network Planner and verify that your account can create and save projects.
Gather topology notes: number of ROADM and OLA sites, fiber lengths, and circuit/service requirements.
Clarify whether the design needs colored or colorless add/drop behavior per site.
Follow these steps to design the topology.
Procedure
Create the base network in Cisco Optical Network Planner.
Log in to the Cisco Optical Network Planner home page with a valid user.
Choose File, then click New.
In Create New Network dialog box, set L0 Network Platform to NCS 1010 and use these system release values: NCS 1010 26.1.1, NCS 1014 26.1.1, and NCS 1004 26.1.1, and set Band Type to C-Band.
Name the network consistently with your deployment tracker (for example, REGION_TOPOLOGY_MMDD).
A new, empty network canvas opens with the drawing tool enabled.
Follow these steps to add sites, fibers, circuits, and services with the drawing tool.
Click the Drawing Tool icon (pencil and ruler).
Add ROADM and OLA sites (for example, ROADM: Genova, Novara, Brescia, and Venezia; pass-through amplifier: Torino, Como, Bergamo, Cremona, and Padova).
Rename sites by selecting Site > Name.
Use the Fiber tool to connect sites following the target topology. At Novara, connect the degrees toward Torino, Como, and Cremona. At Brescia, connect the degrees toward Bergamo, Cremona, and Padova.
By default, fiber length is 1 km for all fibers. To derive fiber length from coordinates, enable Use Coordinates Distance under Network Properties in Entity Editor.
Click on the source site and then the destination site in the map to select Circuit (purple) to add demands.
Both alien and NCS 1000 TXP trunk-to-trunk demands can be created with this option. For the reference topology, create sample circuits across Genova toward Brescia and across the path from Novara OLT61 toward Venezia through Cremona, Brescia OLT-R59, Brescia OLT44, and Padova.
Select Service (green) to create client services of native NCS 1000 TXP.
The service automatically creates a trunk-to-trunk circuit.

The network should be in an analyzed state, and you should have validated the design using the CONP reports.
Generate Cisco Optical Site Manager Netconf XML Files
Generate and prepare Cisco Optical Site Manager Netconf XML files from Cisco Optical Network Planner.
After the network has undergone analysis and validation, it is necessary to export the configuration data from Cisco Optical Network Planner in a Netconf XML format.
The exported files are packaged into a Zip archive, and each file within this archive corresponds to a specific site, identified by its unique naming convention.
Identify the individual site configuration files within the downloaded Zip file.
The Zip file contains a list of files, where each file represents a distinct site. The file name helps to identify the individual site using the format:
<NetworkName-SiteName>
.
Upload each individual site file into Cisco Optical Site Manager after it is operational.
The Cisco Optical Site Manager Netconf XML files are successfully generated, extracted, and prepared for Day1 device configuration in Cisco Optical Site Manager.
What to do next
Bring up the platform and Cisco Optical Site Manager, and then configure the Day 1 device settings in Cisco Optical Site Manager by using the uploaded files.
