I have two extentions in the telephone line on which my data one works.The splitter is attached with only one telephone. The telephone works fine when I am on-line but the other telephone gives noisy sounds which is obvious. My question is can I install one ordinary telephone splitter in the out-put line of my first telephone and give connection to the other telephone which gives noise during internet operations? Or will I have to install ASDL splitter instead?sanjitcx
