If you don’t know what a dry line is for a DSL, it is just a separate DSL number. Usually DSL lines come through the phone line but a dry line will come through your phone line as well but at a different power level so there is a big difference between them. One will never interfere with another and it’s supposedly better. But as always, the bad side is that it costs more.
I am writing about this because my DSL company, Verizon, has been giving me all type of crap about why I haven’t gotten my service in the past 20 days. They suggest a dry line then to keep the line and etc. It is frustrating so do this, next time you get DSL, ask all the questions and try to get Dry Line as that is less likely to cause you any problems.
