I.Basic IPTV Setup Steps
1. Device Connection
• Wired Connection: Set-top box → Fiber optic cable → ITV-dedicated port on optical modem (usually LAN2) -> Set-top box → TV
• Wireless Connection: Dedicated ITV Wi-Fi (name includes ITV logo) -> Set-top box -> TV
2.Optical modem configuration
(1) Access the optical modem management interface via a browser (usually [192.168.1.1](192.168.1.1)), and log in with the super administrator account.
(2) Enable IPTV function:
• Dedicated IPTV Port: Directly check "Enable IPTV" and select the corresponding port (e.g., LAN2).
• Single Port Multiplexing: Go to "Network → VLAN Binding" and bind IPTV and Internet access services to different VLANs on the same port.
3.Set-top box settings
• After powering on, go to settings and select your network connection method (wired/wireless).
• Enter your IPTV account and password (usually the same as your broadband account) to complete authentication.
• Switch the TV signal source to the corresponding HDMI channel to begin watching.
II.Differences in Master-Slave ONU Configurations
1. Differences in functional positioning
| Configuration items |
Key light cat |
Sub-level light cat |
| IPTV function activation | Can be activated directly from the interface | Requires remote configuration of the "Multi-Service" function via the main optical modem |
| VLAN Settings | Configure IPTV and Internet VLAN parameters | Inherit from the main optical modem configuration; generally, no separate configuration is required |
| Port Selection | Any LAN port can be used directly (LAN2 by default) | Only ports authorized by the main optical modem (usually LAN2) can be used |
| Multicast Support | Enable IGMP proxy to process multicast data | Rely on the main optical modem to forward multicast data |
2. Differences in configuration operations
（1）Key points for configuring the main optical modem
• Dedicated IPTV Port: Check "Enable IPTV", select the corresponding port (e.g., LAN2), and save the application.
• Single Port Multiplexing:
a. Unbind the original port bindings for Internet and IPTV.
b. Bind both VLANs (e.g., Internet:45, IPTV:85) to the selected ports simultaneously.
c. Enable multicast functionality (IGMP proxy).
（2）Key points for configuring an optical modem
• Fiber Optic Connection: After enabling the "Multi-Service" function on the main optical modem, the IPTV configuration will be automatically inherited from the modem. Simply connect the set-top box directly to the LAN2 port.
• Ethernet Cable Connection:
a. On the main optical modem, go to "Applications → LAN Port Multi-Service".
b. Select the port to connect to the secondary optical modem (e.g., LAN4) and the "FTTR/PON" option.
On the secondary optical modem, select the IPTV port (usually LAN2) and connect the set-top box.
III.Common Issues and Precautions
- 1.Unable to watch IPTV from the optical modem:
（1）Check if the main optical modem has the "Multi-Service" function enabled and the corresponding port selected.
（2）Confirm that the secondary optical modem is connected to an authorized port (usually LAN2).
（3）Restart the main and secondary optical modems and the set-top box to ensure the configuration takes effect.
2. Precautions for single-port multiplexing:
（1） Must obtain "single-line multiplexing" permission from the operator (separate application required in some regions).
（2）Both the master and slave optical modems and the set-top box must support VLAN functionality.
（3） When the router is connected to this port, IPTV pass-through must be enabled and configured with the same VLAN.
3.IPTV conflicts with internet access services
（1）Ensure that IPTV and internet access use different VLAN IDs (e.g., 45 and 85).
（2）The IPTV port on the optical modem cannot be used for internet access simultaneously (this port will be locked for IPTV only).
IV.Summary
The main optical modem is the "master switch" for IPTV services, responsible for the overall configuration and authorization of IPTV functions; the sub-modems are like "decentral switches," only providing IPTV services within the scope authorized by the main modem. During configuration, the main modem needs to be configured with VLAN parameters and multicast functions, while the sub-modems only need to select a specific port to connect to the set-top box after the main modem has "multi-service" enabled.
