Re: [Line Problem] Cant upgrade but im close enough
David  at the time I wrote the above, the wrong side of a microfilter was all I could think of that might cause the strange conditions, but with more thought I concluded that phone side of the filter would raise the attenuation much higher than 24.0 dB so I don't favor that idea now.
If a passive problem (something like a wrongly connected filter) isn't the problem, then maybe an active and continuous RFI source is cutting down the line's maximum capacity. This sort of problem wouldn't affect the attenuation.
The modem maximum sync tool: »SBC DSL FAQ »How can I check for the maximum attainable sync speeds with a 5100b/4100 modem? might show if something like this was the problem. The tone bin loads might have a "chewed up" or even a "picket fence" look if there was an interference problem. |

there is the info from my tech readout but i have no clue what I'm seeing other than the max rates.
i checked the phone plug and its plugged in correctly. One thing i noticed is the phone line to modem goes under the flouresent lights in the room. Would that affect this. |
