FIOS TELEPHONE - AC HUM

CACTUS24

I HAD FIOS TELEPHONE/INTERNET INSTALLED OVERT THE SUMMER, I AM PLEASED WITH IT...

AN AC HUM STARTED ON THE TELEPHONE, A FEW MONTHS AGO...

HAS ANYONE ALSO HEARD AN AC HUM...

WHEN I UNPLUG THE AC POWER AND RUN ON THE BATTERY THERE IS NO AC HUM...

I CHECKED AROUND THE HOUSE FOR ANY UNSHIELDED TRANSFORMERS, I DO NOT THINK THAT IS THE

PROBLEM...

DO YOU THING THERE IS A PROBLEM IN THE FIOS BOX...

I AM GOING TO REMOVE THE BATTERY TO SEE IF THAT MAKES A DIFFERENCE...

MAYBE THERE IS A PROBLEM WITH THE AC/DC INVERTER IN THE FIOS BOX..

I WAS AN ELECTRONICS PERSON IN THE USMC...

THE TELEPHONE IS A HARDWIRE CONNECTION RIGHT AT THE FIOS BOX...

How many phones do you have in the house? Do you get the hum on all of them?

Can you take the phone out to the ONT and plug directly into the "test" jack on the customer side of the ONT? Do you still get a hum?

If the hum is not present when you plug into the ONT but is present at the phone when jacked in the house, then the phone cable running from the ONT to the wall jack must be passing near either power lines (doesn't need to be a transformer) or an flourescent light (remember all new CFL replacement bulbs for old incadescent bulbs are flourescent as well).

From personal experience, I've had issues with a phone cable running right next to the breaker box as well as a phone cable laying too close to a power cord -- simply reorienting the cable solved that one. It's really a matter of inches in many cases to get far enough away from the source of the noise.
