I have digital phone and telus dsl. My digital phone comes in via cable then connects to a phone jack which is distributed to my phones throughout my house. This must mean that it connects to the phone lines which is the same line that dsl uses which is also connected to a phone wall jack. Or are they separate? It is confusing to me to say the least. I also want to know if I need to put on the dsl filter onto my phones or is this only if I have a land line with telus aswell. Thanks.
