The 10.8 dB is marginal. OTOH, I don't usually see a Noise Margin that low with Attenuation at 41.9 dB. When I had AT&T (legacy SBC, which never, that I know of, deployed ADSL2+ (G.DMT2+)), I had a Noise Margin of 11.0 dB with Attenuation of 51.0 dB.

I have a friend who had an unexpectedly low Noise Margin for her Attenuation. She fixed it by working on the premises wiring.

my info changed when i disconnected my old mechanical bell phone in my bedroom. Are these numbers any better? i hope so because there internet randomly stops sending and receiving data for about a minute every hour or so. im not very tech savy on these kinda things.

The noise margin is much better. Have to ask: Do you have one of these installed?

Micro filter.


You should have one for each POTS ("Plain Old Telephone Service") device. Only the modem should not be filtered.

With your noise margin at 14 dB, you should definitely be capable of faster service. Technically, you would lose some margin as your speed goes up; but if your line can hold 10 dB at 6 Mb, that would be your expected maximum speed.

P.S.: PVC = 8/5, along with ADSL2+, tells me you are in legacy Bellsouth territory. The details of your expected max speed are a bit different from what I know in legacy SBC territory.
