The software of the Nokia ONTs can be updated automatically via the ISAM. We describe here the necessary configuration on the CLI (without AMS) so that the ONTs can all be kept on the same software version.

you should remember that total allowed optical budget from the OLT to the ONT is 28dB. All FTTH design losses from OLT to ONT cannot be bigger than 26,5db (5% margin).In conventional PON based FTTH the minimum transmitter power and minimum receiver sensitivity is set as 0 and -34 dBm.
