Cust has another line he would like to add into his 3x8 rel 6 acs processor. Currently has two lines in the system. Question: The third line he would like to add currently has a fax and dsl on it. Will adding the additional third line cause any problems due to the DSL being on it. I have heard that the DSL will cause problems to the system even with a filter on it. Has anyone done this before?
