LED

Indication

Description
POWER Steady green Indicates that the ONT is powered on.
Off Indicates that the ONT has no power.
XGS-PON Steady green Indicates that the ONT is registered.
Blinking green

Indicates that the ONT is in registering.

Steady red

Indicates the loss of optical signal.

Verify the optical signal

Requirements: Keep an optical meter handy to assess the received optical power reading.

Overview: The LOS LED stays red when the ONT does not detect optical signals from the OLT.

Before you begin

You must verify the optical signal to determine the reason for the loss of signal.

Procedure

Step 1

Ensure that the fiber is securely plugged into the ONT.

If

Then

The LOS LED is off.

You have completed this procedure.

The LOS LED is not off.

Go to step 2.

Step 2

Remove optical fiber from PON port of ONT and connect it to an Optical power meter to check and fix the received optical power reading.

If

Then

The optical power reading is -40 dBm or less

Check the fiber connection for any cut between the ONT and the OLT.

The optical power reading is less than -28 dBm.

Remove the attenuation between the ONT and the OLT to increase the received optical power reading.

The optical power reading is more than -8 dBm.

Add an attenuation between the ONT and the OLT to decrease the received optical power reading.

The received optical power reading must be in the range of -8 dBm to -28 dBm.

Step 3

Determine whether the LOS LED is off.

If

Then

The LOS LED is off

You have completed this procedure.

The LOS LED is not off.

Go to step 4.

Step 4

Check the optical status of the OLT.

Verify the Ethernet service

Before you begin

Verify the Ethernet service if no service is provided to the ONT despite plugging the available Ethernet service into the LAN port.

Procedure

Step 1

Ensure that there is an uninterrupted power supply to the ONT.

  1. Ensure that the POWER LED is on.

  2. Ensure that the power supply is plugged into the ONT, and the power supply connections are secure.

  3. Ensure that the AC power source is on.

Step 2

Ensure that the ONT is correctly registered with the OLT.

  1. Ensure that the PON LED is blinking green.

  2. If the LED blinks green for 30 seconds or more, then use the serial number written at the back of the ONT to check its registration status from the OLT.

Step 3

Verify the optical connection. For the procedure, refer to the section Verifying the optical signal.

Verify the ATA connection

Before you begin

Verify the ATA connection if no service is provided to the ONT despite plugging the available ATA connector into the FXS port.

Procedure

Step 1

Ensure that there is an uninterrupted power supply to the ONT.

  1. Ensure that the POWER LED is on.

  2. Ensure that the power supply is plugged into the ONT, and the power supply connections are secure.

  3. Ensure that the AC power source is on.

Step 2

Ensure that the ONT is correctly registered with the OLT.

  1. Ensure that the PON LED is blinking green.

  2. If the LED blinks green for 30 seconds or more, then use the serial number written at the back of the ONT to check its registration status from the OLT.

Step 3

Ensure that the VoIP service provider is correctly registered with the OLT.

  1. Ensure that the FXS LED is steady green.

  2. If the LED is off, use the serial number written at the back of the ONT to check its registration status from the OLT.

Step 4

Verify the optical connection. For the procedure, refer to the section Verifying the optical signal.

Reboot or reset the ONT

Requirements: Ensure the ONT is plugged in and powered on.

Overview: A reboot restarts the ONT keeping the configuration intact, while a reset brings the ONT back to its factory settings.

Before you begin

Reboot and reset the ONT manually using the reset button.

Procedure

Step 1

To reboot, press the reset button once using a paper clip or needle and release within ~1 second. All the LEDs except POWER will flash (on then off) once, and then the ONT begins rebooting.

Step 2

To factory-reset, press and hold the reset button using a paper clip or needle for ~10 seconds, then release the button. Once the factory-reset has completed, all LEDs (except POWER) will turn off and the system begins rebooting.
