How to check if my Telephone Service is working?

Check the ONT Optical Modem and make sure the indicators are lit in solid green (normal status):


  1. The PON and Tel1 light on the ONT Optical Modem should appear solid green i.e. not flashing.
  2. If the green light is flashing, it may indicate that another user is using the service or the ONT Optical Modem is searching for service connection.
  3. If you have no dial-tone and Tel1 light is flashing, please turn off the ONT Optical Modem for 10 seconds, then turn it back on. Wait for up to 10 minutes when the light should stop flashing. If it’s still flashing, please contact our Customer Care Hotline at 111 and ask for assistance.
  4. If your phone cable is plugged properly in the right socket (Tel1), check that you have a dial tone or a beep sound. If either are absent, your phone set is probably faulty and needs replacing (Refer DIAGRAM B)
  5. If you hear an intermittent beep sound, your service is faulty. Please call our Customer Care at 111 and ask for assistance.
