Centralized OLT Configuration for C-DATA PON Networks

Centralized OLT Configuration for C-DATA PON Networks

Hallo gaess jumpa lagi dengan blog berantakan tapi berpengalama. In today's fast-paced internet service provider (ISP) environment, automation and centralized control are key to reducing deployment time and minimizing technician workload. This article walks you through the centralized configuration of C-DATA OLT devices for Passive Optical Networks (PON), enabling field technicians to focus solely on physical installation while all critical configurations—such as WAN profiles and wireless settings—are managed remotely from the Network Operations Center (NOC).

1. Introduction to PON Networks

Passive Optical Network (PON) is a point-to-multipoint network architecture widely used by ISPs to deliver high-speed broadband services. Unlike traditional active Ethernet networks, PON uses passive optical splitters to distribute signals without requiring external power or active components between the central office and customer premises.

Key Components:

• OLT (Optical Line Terminal): Located at the service provider’s end.
• Splitter: Passively splits the signal to multiple customers.
• ONU/ONT (Optical Network Unit/Terminal): Installed at the customer’s location.

Using C-DATA equipment , especially their OLT and ONU devices, allows for seamless integration and remote configuration capabilities, making it ideal for large-scale deployments.

2. Understanding the Role of OLT in PON Architecture

The OLT (Optical Line Terminal) serves as the heart of any PON network. It connects to the core network and communicates with multiple ONUs over a single fiber using time-division multiplexing.

Why Choose C-DATA OLT?

• Supports GPON/XGS-PON standards
• Built-in web GUI for easy access
• Enables remote provisioning of ONUs
• Compatible with various C-DATA ONUs

When a new customer subscribes, a technician installs the physical link (fiber from the nearest splitter to the home). The rest—authentication, WAN setup, and wireless configuration—is done centrally from the NOC using the OLT interface.

3. Setting Up the Physical Infrastructure

Before diving into configuration, the technician must handle the physical installation :

1. Pull fiber from the ODP (Optical Distribution Point) or nearest Splitter to the customer’s home.
2. Connect the fiber to the ONU device.
3. Power up the ONU and ensure the link is active.

For this guide, we use:

• 1:16 Splitter
• 1:8 Splitter
• Two C-DATA ONUs for demonstration

This setup ensures scalability and flexibility in serving multiple customers efficiently.

4. Configuring the OLT Device Remotely

To manage the OLT, connect your laptop to its management port and assign an IP address within the 192.168.1.x range. Then access the OLT via a browser using its default IP: 192.168.1.100.

Default Login Credentials:

• Username: root
• Password: admin

Once logged in, navigate to the ONU Tab > ONU Autofind to discover unregistered ONUs.

5. Creating and Applying WAN Profiles

WAN profiles define how the ONU connects to the internet. These can be centrally configured and applied to multiple ONUs.

Steps to Create a WAN Profile:

1. Go to Deployment > Profile > WAN Profile
2. Click Add
3. Enter a name (e.g., wan-profile_1)
4. Set VLAN ID = 1 (default)
5. Choose Mode : Bridge, IPoE, or PPPoE
6. For IPoE, set DHCP Client mode
7. Confirm and save

💡 Pro Tip: Use IPoE when deploying dynamic IP addresses. Use PPPoE if you need authentication per user, but note that all ONUs will share the same credentials unless customized later.

---

6. Managing ONU Authentication and Identity

After creating the WAN profile, authenticate the discovered ONUs via the Authentication button under ONU Autofind .

Authentication Options:

• Serial Number Only
• Password Only
• Serial + Password

Apply the previously created Line Profile , Service Profile , and WAN Profile during authentication.

Assign descriptive names like Rumah Ritsi or Rumah Mail in the Device Description under Device Manager for easier monitoring.

7. Centrally Configuring Wireless LAN (SSID)

One of the most requested features from customers is custom SSID configuration . With C-DATA OLTs, you can do this remotely.

Steps to Configure WiFi:

1. Navigate to Service Configuration > WiFi Service
2. Enable Band Steering for unified 2.4GHz and 5GHz SSIDs
3. Set SSID Name (e.g., “Rumah Ritsi”)
4. Choose Security Mode : WPA2/WPA3 or Open
5. Set password or leave open
6. Confirm and wait for sync

This eliminates the need for a technician to manually configure the SSID on-site.

---

8. Troubleshooting and Post-Deployment Checks

After applying configurations, verify them directly on the ONU device.

To Access ONU Web Interface:

• IP Address: 192.168.101.1
• Default Username: adminisp
• Default Password: adminisp

Check:

• WAN Connection Mode
• Public IP Assignment
• WiFi SSID and Password

Ensure that the WAN Profile and WiFi settings match what was configured in the OLT.

9. Advanced Tips: Switching from IPoE to PPPoE

If a customer requires individual PPPoE login (e.g., for billing or usage tracking), you can change the connection mode remotely.

Steps to Change to PPPoE:

1. Go to WAN Service under the selected ONU
2. Clear existing WAN configuration
3. Add new WAN entry
4. Set Mode = PPPoE
5. Enter username/password (e.g., ritsi/ritsi)
6. Confirm and wait for sync

This approach allows for user-specific authentication while maintaining centralized control.

10. Conclusion: Benefits of Centralized OLT Management

By leveraging centralized OLT configuration with C-DATA devices , ISPs can:

• Reduce technician workload to just physical installation
• Standardize service delivery across all customers
• Quickly respond to customer requests (e.g., changing SSID)
• Improve scalability and reduce deployment time

With proper planning and remote configuration tools, managing a large PON network becomes efficient, consistent, and future-ready.

🛠️ Final Notes

• Always clear existing WAN configurations before applying new profiles.
• Ensure ONUs are not pre-configured before deployment.
• Use descriptive naming for better device management.
• Regularly monitor ONU status and connectivity via the OLT interface.
