- LAN Ports (LAN1-LAN4): Connect to PCs (2), IP set-top boxes (4), or TV sets (5).
- TEL Ports (TEL1-TEL2): Connect to telephone sets (6) or fax machines (7).
- POWER Port: Connects to the power adapter (8).
- Side Connections:
- BBU Port: Connects to the backup battery unit (9).
- USB Port: Connects to USB storage devices (10).
- WLAN WPS Button: For easy Wi-Fi setup.
- RESET Button: For device reset.
- Status Indicators: The device features LED indicators on its front panel to display the operational status of various functions, including:
- WPS: Wi-Fi Protected Setup status.
- WLAN: Wireless LAN status.
- USB: USB port status.
- TEL1/TEL2: Telephone port status.
- LAN1-LAN4: Ethernet port status.
- LOS (Loss of Signal): Indicates the status of the optical signal from the OLT.
- PON (Passive Optical Network): Indicates the connection status to the OLT.
- POWER: Device power status.
- Simplified Troubleshooting: The LED indicators provide immediate visual feedback on the device's status, aiding in basic troubleshooting. For example, the LOS and PON indicators are critical for diagnosing network connectivity issues.
Maintenance Features:
While the manual doesn't explicitly detail maintenance procedures, the design and status indicators imply certain maintenance aspects:
- Self-Diagnosis through LEDs: The comprehensive set of LED indicators (WPS, WLAN, USB, TEL1/TEL2, LAN1-LAN4, LOS, PON, POWER) allows users to quickly assess the operational status of different components. This is a primary maintenance feature, enabling users to identify if a specific service (e.g., Wi-Fi, telephone, internet) is experiencing an issue based on the corresponding LED.
- Reset Functionality: The "RESET" button serves as a crucial maintenance tool, allowing users to restore the device to its factory default settings or simply reboot it to resolve minor software glitches.
- Backup Power Support: The BBU port and the ability to connect a backup battery unit contribute to service continuity, reducing downtime during power outages. This is a proactive maintenance feature ensuring critical services remain operational.
- Optical Signal Monitoring: The LOS and PON indicators are vital for monitoring the health of the optical fiber connection.
- LOS (Loss of Signal) Status:
- Off: Indicates that the ONT was disabled by the OLT, or the connection between ONT and OLT is already done, or the connection between ONT and OLT is not succeeded.
- Blink quickly 2 times/second: Indicates that the ONT is trying to connect to the OLT, or the device is detected by the OLT for ONT connection.
- On: Indicates that the connection between ONT and OLT is already done.
- PON (Passive Optical Network) Status:
- Off: Indicates that the ONT was disabled by the OLT.
- Blink quickly 2 times/second: Indicates that the device is detected by the OLT for ONT connection.
- Blink 1-2 seconds: Indicates that the connection between ONT and OLT is not succeeded.
- On: (Implied, but not explicitly stated in the table for PON "On" status, usually means successful connection).
By understanding the meaning of these LED statuses, users can perform initial diagnostics and determine if a problem lies with the device itself, the optical fiber connection, or the service provider's OLT. This empowers users to provide accurate information to technical support if further assistance is needed. The modular design with distinct ports for different services also simplifies component replacement or troubleshooting if a specific port or service fails.
