How to Configure a BDCOM OLT

Introduction

An Optical Line Terminal (OLT) is a device used in fiber-optic communication networks. BDCOM OLTs are popular for their reliability and efficiency in managing fiber-optic networks. Configuring a BDCOM OLT might seem complicated, but with the right guidance, anyone can do it. This guide will walk you through the process, step-by-step, in a way that's easy to understand, even if you're just starting out.

What You'll Need

Before we start, make sure you have the following:

1. BDCOM OLT: The device you'll be configuring.

2. Computer: To access the OLT's settings.

3. Ethernet Cable: To connect your computer to the OLT.

4. Console Cable: If you need to connect directly for initial configuration.

5. Terminal Emulator Software: Such as PuTTY, for accessing the OLT's command line interface (CLI).

Step 1: Setting Up the Physical Connection

1. Power Up the OLT: Plug in the OLT and turn it on.
2. Connect to Your Computer:
* Using an Ethernet Cable: Connect your computer to one of 
   the Ethernet ports on the OLT.
* Using a Console Cable: Connect the console cable to your computer's serial port and the console port on the OLT.
2. Connect to Your Computer:
* Using an Ethernet Cable: Connect your computer to one of 
   the Ethernet ports on the OLT.
* Using a Console Cable: Connect the console cable to your computer's serial port and the console port on the OLT.

Step 2: Accessing the OLT Interface

If you're using an Ethernet cable:

1. Set Your Computer's IP Address:

* Go to your network settings.
* Set your IP address to be in the same range as the OLT. For 
  example, if the OLT’s default IP is 192.168.1.1, set your 
  computer's IP to something like 192.168.1.2.
* Set your IP address to be in the same range as the OLT. For 
  example, if the OLT’s default IP is 192.168.1.1, set your 
  computer's IP to something like 192.168.1.2.

2. Open a Web Browser:

* Type the OLT’s IP address (e.g., 192.168.1.1) into the address bar and press Enter.

* Log in using the default username and password (usually found in the OLT's manual or on the device itself).

If you're using a console cable:

1. Open Terminal Emulator Software (e.g., PuTTY):

* Select the Serial option.
* Set the connection parameters (usually baud rate: 9600, 
   data bits: 8, parity: None, stop bits: 1, flow control: None).
* Click Open to start the session.

2. Log In:

* Enter the default username and password when prompted.

Step 3: Basic Configuration

Once logged in, you need to configure the basic settings:

1. Changing the Password:

* It’s important to change the default password for security 

   reasons.

* In the web interface, navigate to the settings or management section to change the        password.

* In the CLI:

enable

configure terminal

username admin password newpassword

2. Setting the IP Address:

interface vlan 1

ip address 192.168.1.1 255.255.255.0

exit

If you're using the CLI, set the IP address with:

3. Setting the Default Gateway:

* This is the IP address that the OLT will use to reach other 

   networks.

* In the CLI:

   ip route default 192.168.1.254

Step 4: Configuring Gagabit Port & PON Ports

The Gigabit ports are used to connect to a gateway device like Router or Gateway such as Cisco, Juniper, Huawei, Mikrotik or so on. 

PON (Passive Optical Network) ports are used to connect the OLT to ONTs (Optical Network Terminals) at the end-user locations.

1. Create VLANs:

* VLANs (Virtual Local Area Networks) help segregate traffic.

* In the CLI:

   vlan 10

   name UserVLAN

2. Assign Gagabit Ports to VLANs:

* This step associates specific ports with VLANs.
* In the CLI:
 interface GigaEthernet0/1
 description Connected-to-Gateway
 switchport mode trunk
 switchport trunk vlan-allowed 10

3. Assign PON Ports to VLANs:
* This step associates specific ports with VLANs.
* In the CLI:
interface epon 0/1
switchport mode trunk
switchport trunk vlan-allowed 10
exit

4. Configuring ONU (Optical Network Units):

* ONUs are the devices at the customer's premises.

* To register an ONU, use:

   interface epon 0/1

   epon bind-onu mac 00:1A:2B:3C:4D:5E

   exit

Step 5: Save the Running Configuration

To use the same running config when the device will boot next time, we need to save the  current configuration to NVRAM.

* Exit from the global configuration mode.

* In the CLI:

  write all

Step 6: Monitoring and Maintenance

Regular monitoring and maintenance are crucial for a smooth operation.

1. Checking Port Status:

* Monitor the status of the PON ports.

* In the CLI:

show interface brief

2. Viewing Logs:

* Logs help in troubleshooting issues.

* In the CLI:

show logging

3. Backing Up Configuration:

Regularly back up your OLT configuration.

In the CLI:

BDCOM-FTTH#copy startup-config tftp: 192.168.1.2 

Destination file name[startup-config]?BDCOM-FTTH-startup-config[Your Choice]
