Here's a job I did back in 1998 in case the other link didn't work. https://www.contact-directconnect.com/Converged%20Home%20Networks/10base-T%20%20pic%201998.jpg

These 10 Base-T systems work great in residential and here in Calgary their building 10,000 new homes per year . Lots of these new homes only have one cat5e installed. You can still have the same level of funtion on one cable with reduced complexity of having two separate systems. call
More cable cost more money I charge per drop
