ONT (Optical Network Terminal)
This is where the light that passes through the fibre optics on the seethelight network is
converted into electrical signals for use by your telephone or computer. The ONT is typically
located in an understairs cupboard (though this may vary from house to house). It has two or four
internet ports and two telephony ports situated on the underside.
Note:
Make sure your ONT’s power supply is plugged-in and switched on or you will not have a
connection to the seethelight network for both telephony and internet.
The ONT has several lights located on it which tell you its status. These lights can be useful to
help you troubleshoot any problems with your connection.
