I have two phonelines in my office. Line 1 is for voice. Line 2 is for DSL, my fax machine, and for a second phone line. Line 2 is rarely used for voice, but I've noticed since the DSL was installed (about three years) that there is a lot of background noise on line 2. I used the DSL line filters that ATT supplied.
This week my fax machine could send but not receive-it would ring and then you would get a busy signal. After tearing my hair out trying to fix it all week, I replaced the DSL line filter and now it works. The line 2 background noise is also down appreciably with the new filter (but still very noticeable).
My questions-do those filters have a service life? Should they be replaced periodically? Also, are there better and lesser quality ones available-and if so, what are the best? Finally, I've used DSL in single phone line homes that had a lot better line quality than I'm getting on line 2-any ideas?
