I want to ask how can i put a splitter in the middle of bsnl phone line that comes from the tower in front of the house to my roof. I have an extra dsl modem that i want to use in a room on 1st floor . so i want to install the splitter in the middle of the wire .the question is splitter that i have requires rj45 port . i want to ask if there are simple splitters available that i can use means which just take the mire in them ,not the rj45 type but simple copper wire in them or should i just make a joint in the middle of thewire and take other wire to room through that joint .
