I found a few threads on this, but didn't see my exact question addressed. All my phone lines are run in a loop using Cat5 cabling. I understand that without homeruns I can't put them all to a single switch. My idea is to put RJ45 heads on both cables at each existing phone jack, which create the loop, and run them into a 4-port dummy switch. So, each room in my house with a phone jack will now have a 4-port switch with 2 open ports. Then, I just plug my router into the loop and voila...a home network with internet. Will this work? What simple thing am I missing? Seems too easy. Is daisy-chaining dumb switches even possible?
