ONT Error lights

Is the ONT the same as what CitryFibre install? Trying to work out the error lights on the ONT for my parents. They do have an engineer coming today though.
 
Not sure what Cityfibre install but Toob use an Adtran SDX620 series there are a few variants but it’s the 1GBE version.

The LEDs are

Power ( power symbol)
Optical (laser symbol) if it’s Red then you have no optical signal)
Ethernet (computer symbol) - flashing green = activity.

Normal operation is Power and optical should be solid green, Ethernet should be flashing Green.
 
Not sure what Cityfibre install
Typically it's been the Calix 801G for older installs where they used GPON and the Calix GP1100X for the newer XGS-PON Installs.

There are a few other models out there being used on the CityFibre network but these two are pretty much your standard issue ONTs that you're most likely to encounter.

If Toob use Adtran outside of the CityFibre network then there's definitely no overlap on hardware choice however.

My Cityfibre ONT done in late April GPON install is a Calix GP1000G model. 4 LED's. The pic below is a GP1100G with an extra POTS thats not present on my unit, but otherwise is the same.

If it's unclear what the LEDs refer to then unplugging the fibre is usually a good test - if the lights change then the error was that the ONT could see light but wasn't provisioned on the network or there was some other fault relating to that, if the lights don't change then the fault was likely a fibre break.
