Re: SN Margin
I have a question over in Direct, but since we're on the topic of SN. My phone line has developed a low pitched hum last month. I haven't called to have that checked yet, but would that frequency affect the SN that you guys are talking about? |

| An audible hum is a POTS problem and should be reported via 611 without mentioning that you have DSL on your phone line. The hum might be from power line interference.
Anything that degrades the POTS quality will also affect the DSL to some degree. So higher harmonics of that audible frequency might affect your DSL signal which would reduce your SN margin and increase your CRC error rate. |
